Autopsy reports typically indicate that the jumpers have lacerated aortas, livers, spleens, and hearts.
|
|
The Bajau had spleens about 50 percent bigger on average than those of the Saluan.
|
|
One variant of a gene called PDE10A influenced the size of spleens in the Bajau.
|
|
People with one copy of the mutant gene had bigger spleens than those with none.
|
|
Studies have shown that larger spleens can aid in deep diving among marine animals. 5.
|
|
Overall, the Bajau people had spleens about 50 percent larger than the Saluan, the study found.
|
|
Research on diving seals has suggested that larger spleens could be linked to longer dive times.
|
|
Babesiosis, a red blood cell infection, can be fatal for people with damaged or missing spleens.
|

In experiments where Schedlowski cut the nerve running to rats' spleens, the conditioned response was completely blocked.
|

And scientists have found that injecting thyroid into mice with stunted spleens can make the organs grow larger.
|
|
Ethan's insides are a math all their own: two left lungs, five spleens, and nine congenital heart defects.
|
|
The bacteria causes lesions and hemorrhaging in infected fish, and swells their kidneys and spleens, eventually killing them.
|
|
Scientists suspect that the reflex helps them dive deeper — as it turns out, seals with bigger spleens can dive deepest.
|
|
Sierra has other plans for the drug, focusing it primarily on anemia as well as enlarged spleens in myelofibrosis patients.
|
|
She returned a few months later, this time with a portable ultrasound machine to measure the size of the Bajau people's spleens.
|
|
"If natural selection had acted in seals to give them larger spleens, then it might've done the same thing in humans," Ilardo said.
|
|
Those at greatest risk are people with weakened immune systems, such as cancer patients and people who have had their spleens removed, the CDC said.

Those at greatest risk are people with weakened immune systems, such as cancer patients and people who have had their spleens removed, according to the CDC.
|
|
Her new study may have uncovered genetic adaptations that allow the Bajau to go for longer periods without oxygen -- and which might give them unusually large spleens.
|
|
The results of the study, published today in Cell Press, suggests their unusually large spleens are the result of a genetic mutation, and not a lifestyle-related phenomenon.
|
|
When they reintroduce her spleen removal from the hacking who grew new tiny spleens in her brain, I placed my bet on the two of them working together.
|
|
Figuring this was a clue to extraordinary breath-holding ability, lead researcher Melissa Ilardo brought a portable ultrasound machine to southeast Asia to measure the size of Bajau spleens.
|
|
Chronic myeloid leukemia, which in poor countries is often diagnosed late, when victims have distended spleens and soaring white cell counts, "was once a death sentence," Dr. Radich said.
|
|
Ethan was born with nine congenital heart defects, has two left lungs, and five spleens; his liver, gallbladder, heart, and stomach are all in the wrong place, Chandra told CNN.
|
|
The researchers' findings reveal that the Bajau — regardless of whether they're divers or have other jobs — have spleens that are about 50 percent bigger than those who live 15 miles inland.
|
|
New research suggests these impressive feats aren't the result of training, but rather, an example of natural selection at work—which, in this case, has endowed Bajau individuals with abnormally large spleens.
|
|
To do so, Ms Ilardo travelled to Indonesia and recruited 59 Bajau who were willing to give her samples of saliva for DNA analysis and also to have their spleens measured ultrasonically.
|
|
Then, scanning the Bajau DNA for clues, the researchers identified a possible culprit for their larger spleens: a variant of a gene called PDE10A, which has been linked to higher-than-average thyroid hormone levels in Europeans.
|
|
Through a "full necropsy" and "3D computed tomography — or CT scan — and a magnetic resonance imaging at the University of Minnesota's Veterinary Diagnostic Laboratory," researchers were able to find that the fawns had a shared liver but two hearts and more than two spleens.
|
|
He found that their conditioned response to saccharin suppresses proliferation of white blood cells in their spleens, and cuts the production of two vital chemicals that the immune system uses for signalling (the cytokines IL-2 and IFN-γ), just as the drug does.
|

It's not often you find yourself in the presence of a spirit traveler and energy surgeon, someone who claims to "defy time and space daily" and is able to "repair hearts, spleens, livers, gallbladders, cancers, and bones" simply through the healing power of touch.

But in the absence of Mr. Trump, who instead gave a rally in Harrisburg, Pa., Mr. Minhaj, a correspondent on Comedy Central's "Daily Show," and Ms. Bee, the host of TBS's "Full Frontal," took a page from the playbook of this president, whose relationship with the news media has been singularly contentious, and vented their spleens at the press.
|
|
Cetaceans and pinnipeds that prolong apnea must optimize the size and use of their oxygen stores, and they must deal with the accumulation of lactic acid due to anaerobic metabolism. Beaked whales have several anatomical adaptations to deep diving: large spleens, livers, and body shape. Most cetaceans have small spleens. However, beaked whales have much larger spleens than delphinids, and may have larger livers, as well.
|
|
Although present, the multiple small spleens are often ineffective; this is termed functional asplenia.
|
|
An accessory spleen is a small splenic nodule extra to the spleen usually formed in early embryogenesis. Accessory spleens are found in approximately 10 percent of the population and are typically around 1 centimeter in diameter. Splenosis is a condition where displaced pieces of splenic tissue (often following trauma or splenectomy) autotransplant in the abdominal cavity as accessory spleens. Polysplenia is a congenital disease manifested by multiple small accessory spleens, rather than a single, full-sized, normal spleen.
|
|
Accessory spleens may undergo hypertrophy after splenectomy Very rarely, it may cause bleeding (pictured).Note: The case is possibly splenosis rather than an accessory spleen: If splenectomy is performed for conditions in which blood cells are sequestered in the spleen, failure to remove accessory spleens may result in the failure of the condition to resolve. During medical imaging, accessory spleens may be confused for enlarged lymph nodes or neoplastic growth in the tail of the pancreas, gastrointestinal tract, adrenal glands or gonads.
|
|
Isomeric patients often experience disruptions to splenic development during embryogenesis, resulting in an overall lack a spleen (asplenia) or development of many spleens (polysplenia). Asplenia is most often observed in patients with right atrial isomerism. Polysplenia results in 90% of patients with left atrial isomerism. Although they have many spleens, each is usually ineffective resulting in functional asplenia.
|
|
The clearest evidence for the diagnosis of SMZL is obtained by examination of patients' spleens obtained by splenectomy. These spleens characteristically show lymphoid infiltrates in the white pulp and, to a lesser and more variable extent, the red pulp. These infiltrates consist of small lymphocytes, marginal zone B-cells, centroblast- like B-cells, monocyte-like B-cells, and plasma cells. Epithelioid-like histiocytes may be found in the red pulp.

|
It seems apparent that many dogs of the breed suffer enlarged spleens for no obvious reason other than the spleen may have been constantly twisting, folding and unfolding.
|
|
They suffer from severe hemolytic anemia, and occasional hepatomegaly has been documented. Parasitemia levels can reach up to 85% in patients without spleens, compared to 1–10% in individuals with spleens and effective immune systems. Complications include acute respiratory failure, congestive heart failure, and kidney failure. Infections can be fatal in 5–10% of hospitalized patients, with increased risk of death in the immunosuppressed, the elderly, and those also infected with Lyme disease.
|
|
Exposure to DCPA has shown damaging effects in the adrenal glands, kidneys, livers, thyroids, and spleens of laboratory animals. The effects on the rabbits included decreased motor activity and poor reflexes.
|
|
Due to the mammalian dive reflex, the spleen contracts when the mammal dives and releases the oxygen-carrying red blood cells. Over time, individuals with larger spleens were more likely to survive and thrive because free-diving can actually be quite dangerous. By contrast, communities centered around farming show no signs of evolving to have larger spleens. Because the Sama-Bajau show no interest in abandoning this lifestyle, there is no reason to believe further adaptations will not occur.
|
|
Polysplenia sometimes occurs alone, but it is often accompanied by other developmental abnormalities such as intestinal malrotation or biliary atresia, or cardiac abnormalities, such as dextrocardia. These accessory spleens are non-functional.
|
|
Splenectomy can produce long-term remissions in patients whose spleens seem to be heavily involved, but its success rate is noticeably lower than cladribine or pentostatin. Splenectomies are also performed for patients whose persistently enlarged spleens cause significant discomfort or in patients whose persistently low platelet counts suggest idiopathic thrombocytopenic purpura. Bone marrow transplants are usually shunned in this highly treatable disease because of the inherent risks in the procedure. They may be considered for refractory cases in younger, otherwise healthy individuals.
|
|
They are medically significant in that they may result in interpretation errors in diagnostic imaging or continued symptoms after therapeutic splenectomy. Polysplenia is the presence of multiple accessory spleens rather than one normal spleen.
|
|
At presentation, patients (median age 65 years; range 30–90 years) generally exhibit enlargement of their spleens (75% of cases). They typically do not have enlargements of their lymph nodes except for the lymph nodes around the hilum of their spleens. Most patients have no systemic symptoms such as fever, night sweats, weight loss, or fatigue. Blood tests reveal reductions in the levels of red blood cells, platelets, and/or white blood cells in 25% of cases; an abnormal circulating IgM myeloma protein in <33% of cases; and in ~20% of cases evidence of autoimmunity abnormalities such as circulating autoantibodies (i.e.

In India, the Charaka Samhita and Sushruta Samhita document malaria. These documents list the main symptoms as fever and enlarged spleens. The Bhrigu Samhita from 1000 BCE makes the earliest reference to Amebiasis. The symptoms were given as bloody and mucosal diarrhea.
|
|
In a 2004 study researchers used MRI to observe physiological changes of the spleens of 5 seal pups during simulated dives. By 3 minutes, the spleens on average contracted to a fifth of their original size, indicating a dive-related sympathetic contraction of the spleen. Also, a delay was observed between contraction of the spleen and increased hematocrit within the circulating blood, and attributed to the hepatic sinus. This fluid- filled structure is initially expanded due to the rush of RBC from the spleen and slowly releases the red blood cells into the circulatory system via a muscular vena caval sphincter found on the cranial aspect of the diaphragm.
|
|
Patients with splenomegaly (enlarged spleen), unfit for systemic treatment or refractive to chemotherapy may have their spleens removed via splenectomy or undergo splenic irradiation in order to relieve pain, control their symptoms, and allow removal of a major proliferative focus and tumour bulk in this disease. Splenic irradiation has been used in the treatment.
|
|
Polysplenia is a congenital disease manifested by multiple small accessory spleens, rather than a single, full-sized, normal spleen. Polysplenia sometimes occurs alone, but it is often accompanied by other developmental abnormalities. Conditions associated with polysplenia include gastrointestinal abnormalities, such as intestinal malrotation or biliary atresia, as well as cardiac abnormalities, such as dextrocardia.
|
|
If an individual's spleen is enlarged, as is frequent in mononucleosis, most physicians will advise against activities (such as contact sports) where injury to the abdomen could be catastrophic. Patients whose spleens have been removed must receive immunizations to help prevent infections such as pneumonia. This helps to replace the lost function of this organ.
|
|
Single case reports also describe splenosis in the thoracic cavity, in subcutaneous tissue, in the liver or in the cranial cavity. Splenosis must be distinguished from the presence of additional spleens, which are innate and are the result of differences in embryological development. Additionally, splenosis must be differentiated from malignant tumors.R. D. Fremont, T. W. Rice: Splenosis: A Review.

|
The spleen is located and disconnected from its arteries. The ligaments holding the spleen in place, gastrosplenic ligament, splenorenal ligament and splenocolic ligament, are dissected and the organ is removed. In some cases, one or more accessory spleens are discovered and also removed during surgery. The incisions are closed and when indicated, a drain is left.
|
|
A 28-year follow-up of 740 World War II veterans whose spleens were removed on the battlefield showed a significant increase in the usual death rate from pneumonia (6 rather than the expected 1.3) and an increase in the death rate from ischemic heart disease (41 rather than the expected 30), but not from other conditions.
|
|
An accessory spleen is a small nodule of splenic tissue found apart from the main body of the spleen. Accessory spleens are found in approximately 10 percent of the population and are typically around 1 centimetre in diameter. They may resemble a lymph node or a small spleen. They form either by the result of developmental anomalies or trauma.

|
The symptoms of LSD vary depending on the particular disorder and other variables such as the age of onset, and can be mild to severe. They can include developmental delay, movement disorders, seizures, dementia, deafness, and/or blindness. Some people with LSD have enlarged livers or spleens, pulmonary and cardiac problems, and bones that grow abnormally.

Domestic mink, which are bred in fur farms and are substandard genetically, have 19.6% smaller brains, 8.1% smaller hearts, and 28.2% smaller spleens than wild mink. The feet are broad, with webbed digits. It generally has eight nipples, with one pair of inguinal teats and three pairs of abdominal teats. The adult male's penis is long, and is covered by a sheath.

The spleen becomes torsed because it is no longer anchored in its correct location. In a normal Greater Swiss Mountain Dog the spleen is smooth and uncreased; it is about by , and less than thick. Most of the spleens removed from Greater Swiss Mountain Dogs are by and very thick. This size spleen is not an abnormal finding in this breed.

Erythrocytes with membrane pits can be indicative of splenic dysfunction as a healthy spleen clears blood of pitted erythrocytes. Pitted erythrocytes can be counted using Normarsky optics. Humans with healthy spleens have less than two percent of their red blood cells contain pits. In comparison, a person with asplenia may have up to 50% of their red blood cells contain pits.

For example, 99mTc-EC20 was reported to concentrate in the livers, spleens and arthritic extremities of adjuvant-induced arthritic rats via a folate-dependent mechanism. Development of folate-drug conjugates for inflammation therapy is underway. It is expected that ailments which harbor activated macrophages (such as arthritis, psoriasis and inflammatory bowel disease) may someday be treatable with folate-targeted medicines.

Howell–Jolly bodies are seen with markedly decreased splenic function. Common causes include asplenia (post-splenectomy) or congenital absence of spleen (heterotaxy syndrome with asplenia). Spleens are also removed for therapeutic purposes in conditions like hereditary spherocytosis, trauma to the spleen, and autosplenectomy caused by sickle cell anemia. Other causes are radiation therapy involving the spleen, such as that used to treat Hodgkin lymphoma.

The modern name of the town, Radès, derives from the Latin expression "Maxula per races" (Maxula by the ferries), Maxula being the original Libyco-Berber name of the village near which is in the Antiquity a station of boats whose function is To connect the terminus of the coastal road with Carthage by sea. The Arabs have retained from this toponymic designation only spleens which they have transformed into Rades.
|
|
A splenectomy also results in a greatly diminished frequency of memory B cells. A 28-year follow-up of 740 World War II veterans who had their spleens removed on the battlefield showed a significant increase in the usual death from pneumonia (6 deaths rather than the expected 1.74) and an increase in the deaths from ischemic heart disease (41 deaths rather than the expected 30.26) but not from other conditions.

|
In other cases, symptoms are characterized by irregular fevers, chills, headaches, general lethargy, pain, and malaise. In severe cases effects of parasitic multiplication, symptoms like hemolytic anemia, jaundice, shortness of breath, and hemoglobinuria have been documented. Individuals with normal immune function and healthy spleens often recover without treatment. Splenectomized patients are more susceptible to contracting the disease and can die within five to eight days of symptom onset.

The leftover pieces that come from the process of stripping meat from animals tends to get used for different purposes. One of them is to put these parts into pet food. Many large, well- known pet food brands use animal by-products as protein sources in their recipes. This can include animal feet, livers, lungs, heads, spleens, etc or an admixture in the form of meat and bone meal.

They observed that small raised lumps grew on the spleens of the mice, in proportion to the number of bone marrow cells injected. Till and McCulloch dubbed the lumps 'spleen colonies', and speculated that each lump arose from a single marrow cell: perhaps a stem cell. In later work, Till and McCulloch were joined by graduate student Andy Becker. They cemented their stem cell theory and in 1963 published their results in Nature.

From 1902, Carrel performed transplant experiments on dogs. Surgically successful in moving kidneys, hearts, and spleens, he was one of the first to identify the problem of rejection, which remained insurmountable for decades. The discovery of transplant immunity by the German surgeon Georg Schöne, various strategies of matching donor and recipient, and the use of different agents for immune suppression did not result in substantial improvement so that organ transplantation was largely abandoned after WWI.

It is also used to prevent bacterial endocarditis in high-risk people having dental work done, to prevent Streptococcus pneumoniae and other encapsulated bacterial infections in those without spleens, such as people with sickle-cell disease, and for both the prevention and the treatment of anthrax. The United Kingdom recommends against its use for infectious endocarditis prophylaxis. These recommendations do not appear to have changed the rates of infection for infectious endocarditis.

Pediatric patients with sickle cell disease and beta thalassemia experience multiple splenic infarcts, resulting in splenic fibrosis and scarring. Over time, this leads to a small, auto infarcted spleen typically by the time patients reach adulthood. Splenic sequestration crisis can only occur in functioning spleens which may be why this crisis is rarely seen in adults. However, late adolescent or adult patients in this group who maintain splenic function may develop splenic sequestration crisis.

Salmonella was first visualized in 1880 by Karl Eberth in the Peyer's patches and spleens of typhoid patients. Four years later, Georg Theodor Gaffky was able to successfully grow the pathogen in pure culture. A year after that, medical research scientist Theobald Smith discovered what would be later known as Salmonella enterica (var. Choleraesuis). At the time, Smith was working as a research laboratory assistant in the Veterinary Division of the United States Department of Agriculture.

Another option, suitable for Rh-positive patients with functional spleens is intravenous administration of Rho(D) immune globulin [Human; Anti-D]. The mechanism of action of anti-D is not fully understood. However, following administration, anti-D-coated red blood cell complexes saturate Fcγ receptor sites on macrophages, resulting in preferential destruction of red blood cells (RBCs), therefore sparing antibody-coated platelets. There are two anti-D products indicated for use in patients with ITP: WinRho SDF and Rhophylac.

Tompkins' most famous celebrity was Gus Wickstrom who was known worldwide, and was featured on such programmes as the Daily Show, numerous Canada-wide TV shows, and various other USA TV and radio shows. He predicted the weather by looking at raw pig spleens for their colour, width, length and fatty deposits. From this, he predicted temperature, extreme heat/cold periods, snow/rainfall and drought up to eight months in advance. This is a famous practice dating back to his Scandinavian heritage.

In Israel, Jerusalem mixed grill (Hebrew: מעורב ירושלמי) (me'orav Yerushalmi) consists of chicken hearts, spleens, and liver mixed with bits of lamb cooked on a flat grill, seasoned with onion, garlic, black pepper, cumin, turmeric, and coriander. In Lebanon, lamb brain is used in nikhaat dishes and sometimes as a sandwich filling. A tradition practiced less often today would be to eat fish eyes either raw, boiled, or fried. Another popular dish in the region surrounding is korouch, which is rice-stuffed sheep intestine.

IFN-producing cells (mIPCs) were absent in all lymphoid organs from ICSBP knockout (KO) mice, as revealed by lack of CD11clowB220+Ly6C+CD11b− cells. In parallel, CD11c+ cells isolated from ICSBP KO spleens were unable to produce type I IFNs in response to viral stimulation. ICSBP KO mice also displayed a marked reduction of the DC subset expressing the CD8alpha marker (CD8alpha+ DCs) in spleen, lymph nodes, and thymus. Moreover, ICSBP-deficient CD8alpha+ DCs exhibited a markedly impaired phenotype when compared with WT DCs.

Many mammals have tiny spleen-like structures known as haemal nodes throughout the body that are presumed to have the same function as the spleen. The spleens of aquatic mammals differ in some ways from those of fully land-dwelling mammals; in general they are bluish in colour. In cetaceans and manatees they tend to be quite small, but in deep diving pinnipeds, they can be massive, due to their function of storing red blood cells. The only vertebrates lacking a spleen are the lampreys and hagfishes (the Cyclostomata).

Jerusalem mixed grill () (me'orav Yerushalmi) is a grilled meat dish considered a specialty of Jerusalem. It consists of chicken hearts, spleens and liver mixed with bits of lamb cooked on a flat grill, seasoned with onion, garlic, black pepper, cumin, turmeric, olive oil and coriander. The dish is said to have been invented at the Mahane Yehuda Market, with various restaurants claiming to be the originators. In 2009, Israeli chefs created a giant portion that weighed in at 440 pounds (200 kilos), winning a Guinness world record for the largest Jerusalem mixed grill.

Together with his colleague, Dr. J.E. Till, McCulloch created the first quantitative, clonal method to identify stem cells and used this technique for pioneering studies on stem cells. His experience in hematology, when combined with Till's experience in biophysics, yielded a novel and productive combination of skills and interests. In the early 1960s, McCulloch, and Till started a series of experiments that involved injecting bone marrow cells into irradiated mice. Visible nodules were observed in the spleens of the mice, in proportion to the number of bone marrow cells injected.

If this failed to cure a patient, he sought sources of infection in tonsils and sinuses and often a tonsillectomy was recommended as additional treatment. If a cure was not achieved after these procedures, other organs were suspected of harboring infection. Testicles, ovaries, gall bladders, stomachs, spleens, cervixes, and especially colons were suspected as the focus of infection and were removed surgically. Being before even rudimentary scientific methods such as control groups—and by extension, double-blind experiments—existed, statistical methodology for applications in human behavior and medical research did not emerge during the lifetime of Cotton.

The increased risk of infection is due to inability to clear opsonised bacteria from circulating blood. There is also a deficiency of T-cell independent antibodies, such as those reactive to the polysaccharide capsule of Streptococcus pneumoniae.Kasper, D. et al (2015) Harrison's principles of internal medicine. New York, NY: McGraw-Hill Education The risk to asplenic patients has been expressed as equivalent to an adult dying in a road traffic accident (in every 100 people without spleens, 1 to 5 would develop a severe infection per decade) (reference UK Splenectomy Trust Advice)—hence sensible precautions are advisable.

Data obtained from the Archives of the Venetian State, relating to an operation organized by the Venetian Intelligence Services, describes a plan aimed at lifting the siege by infecting the Ottoman soldiers with plague; this was to be done by attacking them with a liquid made from the spleens and buboes of plague victims. "Although the plan was perfectly organized, and the deadly mixture was ready to use, the attack was ultimately never carried out." According to a scholar from the National Defense University, this attack was previously unknown to historians of biological warfare until published in December 2015.

Mammals are a highly radio-sensitive class, and observations of mice in the surrounding area of Chernobyl showed a population decrease. Embryonic mortality increased as well, however, migration patterns of the rodents made the damaged population number increase once again. Among the small rodents affected, it was observed that there were increasing issues in the blood and livers, which is a direct correlation to radiation exposure. Issues such as liver cirrhosis, enlarged spleens, increased peroxide oxidation of tissue lipids, and a decrease in the levels of enzymes were all present in the rodents exposed to the radioactive blasts.

Further complicating the life- cycle, but still with regard to geographical distribution, P. peromysci adults have been identified in New York as well as in Pennsylvania in flying squirrel populations. In the flying squirrel hosts, another parasite, Strongyloides robustus was also identified. The scientists hypothesized that perhaps initial infection with S. robustus via skin penetration of the flying squirrel host might alter the immune response of the host in such a way which encourages co- infection of the gastrointestinal tract with P. peromysci (5). Furthermore, in the flying squirrels the pathology wasn’t deemed severe from spleen masses collected from the squirrels as the spleens were not appreciably enlarged from pathology.

In a sub chronic rat oral study, mortality, clinical signs, body weights, food consumption and efficiency, urinalysis and gross pathology were unaffected by novaluron. At 2000 ppm, cumulative body weight gains were observed and some histopathological changes in the spleens were noted; however, these effects were not statistically significant. Based on these histopathological parameters in the spleen, the no observed adverse effect level(NOAEL) was estimated to be 8.3 mg/kg/day while the lowest observed adverse effect level(LOAEL) was 818.5 mg/kg/day. A 28-day rat dermal toxicity study was conducted to evaluate dermal exposure, the route most directly applicable to the indoor use on ornamentals grown in containers.

Patients typically present with enlarged lymph nodes in the neck, arm pit, and groin areas but on further examination are found to have involvement of their spleen (31% of cases), liver (52% of cases), bone marrow (27% of cases) and lung/or (13%) as determined by finding enlarged spleens and/or livers on physical examination or medical imaging; abnormal results on liver function tests, and/or THRLBCL infiltrates in bone marrow biopsies. Rare cases of the disease have presented with involvement of the skin (termed primary cutaneous THRLBCL), thyroid gland, thymus, gastrointestinal tract, pancreas, jaw bone, nasopharynx, brain, tongue, uterus, stomach, and soft tissues. Many patients will also complain of having systemic B symptoms such as fever, night sweats, weight loss, and malaise.

Alfred Velpeau The first published description of a case of leukemia in medical literature dates to 1827 when French physician Alfred-Armand-Louis- Marie Velpeau described a 63-year-old florist who developed an illness characterized by fever, weakness, urinary stones, and substantial enlargement of the liver and spleen. Velpeau noted the blood of this person had a consistency "like gruel", and speculated the appearance of the blood was due to white corpuscles. In 1845, a series of people who died with enlarged spleens and changes in the "colors and consistencies of their blood" was reported by the Edinburgh-based pathologist J.H. Bennett; he used the term "leucocythemia" to describe this pathological condition. The term "leukemia" was coined by Rudolf Virchow, the renowned German pathologist, in 1856.

Henry Cotton, at the top left corner, with the ice hockey team of the University of Maryland during the 1896–1897 season Henry Andrews Cotton (May 18, 1876 - May 8, 1933) was an American psychiatrist and the medical director of New Jersey State Hospital at Trenton (now the Trenton Psychiatric Hospital, previously the New Jersey State Lunatic Asylum) in Trenton, New Jersey from 1907 to 1930. He and his staff practiced experimental surgical bacteriology on patients, including the routine removal of some or all of patients' teeth, their tonsils, and frequently spleens, colons, ovaries, and other organs. These practices continued long after careful statistical reviews falsified Cotton's claims of extraordinarily high cure rates, and demonstrated very high mortality and morbidity as a result of these aggressive and dangerous measures.Ian Freckelton.

More than a thousand years of subsistence freediving associated with their life on the sea appear to have endowed the Bajau with several genetic adaptations to facilitate their lifestyle. A 2018 study showed that Bajau spleens are about 50 percent larger than those of a neighboring land-based group, the Saluan, letting them store more haemoglobin-rich blood, which is expelled into the bloodstream when the spleen contracts at depth, allowing breath-holding dives of longer duration. This difference is apparently related to a variant of the PDE10A gene. Other genes that appear to have been under selection in the Bajau include BDKRB2, which is related to peripheral vasoconstriction, involved in the diving response; FAM178B, a regulator of carbonic anhydrase, which is related to maintaining blood pH when carbon dioxide accumulates; and another one involved in the response to hypoxia.

Malaria became widely recognized in ancient Greece by the 4th century BC, and is implicated in the decline of many city-state populations. The term μίασμα (Greek for miasma): "stain, pollution", was coined by Hippocrates of Kos who used it to describe dangerous fumes from the ground that are transported by winds and can cause serious illnesses. Hippocrates (460–370 BC), the "father of medicine", related the presence of intermittent fevers with climatic and environmental conditions and classified the fever according to periodicity: Gk.:tritaios pyretos / L.:febris tertiana (fever every third day), and Gk.:tetartaios pyretos / L.:febris quartana (fever every fourth day). The Chinese Huangdi Neijing (The Inner Canon of the Yellow Emperor) dating from ~300 BC – 200 AD apparently refers to repeated paroxysmal fevers associated with enlarged spleens and a tendency to epidemic occurrence.

Follicular B helper T cells (also known as just follicular helper T cells or TFH), are antigen-experienced CD4+ T cells found in the periphery within B cell follicles of secondary lymphoid organs such as lymph nodes, spleens and Peyer's patches, and are identified by their constitutive expression of the B cell follicle homing receptor CXCR5. Upon cellular interaction and cross- signaling with their cognate follicular (Fo B) B cells, TFH cells trigger the formation and maintenance of germinal centers through the expression of CD40 ligand (CD40L) and the secretion of IL-21 and IL-4. TFH cells also migrate into these seeded germinal centers, predominantly composed of rapidly dividing and mutating B cells. Within germinal centers, TFH cells play a critical role in mediating the selection and survival of B cells that go on to differentiate either into special plasma cells capable of producing high affinity antibodies against foreign antigen, or memory B cells capable of quick immune re- activation in the future if ever the same antigen is re-encountered.

SNX8 plays an antiviral role against Listeria monocytogenes through the IFNγ-triggered IKKβ-mediated noncanonical signaling pathway; murine cells expressing SNX8 under this infection showed a higher expression and secretion of IFNβ and IL6 cytokines in blood and lower presence of bacteria in liver and spleens, which resulted in a reduction of Listeria monocytogenes lethality, in comparison to SNX8-negative induced murine cells. In addition, SNX8 plays an antiviral role against DNA viruses such as HSV-1 through the MITA-mediated activation of the IFNβ promoter; murine cells expressing SNX8 under this infection showed a higher expression and secretion of IFNβ and IL6 cytokines in blood and a decreased presence of cerebral viral titers, which resulted in a reduction of HSV-1 lethality, in comparison to SNX8-negative induced murine cells. Finally, SNX8 also plays an antiviral role against RNA viruses such as SeV (Sendai virus) through VISA- mediated activation of the IFNβ promoter; murine cells expressing SNX8 under this infection showed a higher expression and secretion of IFNβ and IL6 cytokines in blood and a reduced presence of viral accumulations, which resulted in a reduction of SeV lethality, in comparison to SNX8-negative induced murine cells.
