Marx SO, Reiken S, Hisamatsu Y, Gaburjakova M, Gaburjakova J, Yang YM, Rosemblit N, Marks AR. Phosphorylation-dependent regulation of ryanodine receptors: a novel role for leucine/isoleucine zippers. J Cell Biol. 2001 May 14;153(4):699-708. doi: 10.1083/jcb.153.4.699. PMID: 11352932; PMCID: PMC2192391.
Abstract Ryanodine receptors (RyRs), intracellular calcium release channels required for cardiac and skeletal muscle contraction, are macromolecular complexes that include kinases and phosphatases. Phosphorylation/dephosphorylation plays a key role in regulating the function of many ion channels, including RyRs. However, the mechanism by which kinases and phosphatases are targeted to ion channels is not well understood.…

Heparin-induced thrombocytopenia (HIT) is the development of thrombocytopenia (a low platelet count), due to the administration of various forms of heparin, an anticoagulant. HIT predisposes to thrombosis (the abnormal formation of blood clots inside a blood vessel).
When thrombosis is identified the condition is called heparin-induced thrombocytopenia and thrombosis (HITT). HIT is caused by the formation of abnormal antibodies that activate platelets, which release microparticles that activate thrombin, leading to thrombosis. If someone receiving heparin develops new or worsening thrombosis, or if the platelet count falls, HIT can be confirmed with specific blood tests. The treatment of HIT requires stopping…

Cyanamide notes (it was a polio vaccine that spurred these notes and by now polio has five mentions on the page and these are two of them)
I’m going to add some polio vaccine stuff at the top of these notes. Hilary Koprowski is the one mentioned on the Polio Hall of Fame page who was not included in the hideous monument, see What In God’s Name, even though he (and his work) have direct connection to those who are included. He…

Adenosine deaminase deficiency (ADA deficiency) was discovered in 1972 and recognized as the first immunodeficiency disorder
Adenosine deaminase deficiency (ADA deficiency) is a metabolic disorder that causes immunodeficiency. It is caused by mutations in the ADA gene. It accounts for about 10–15% of all cases of autosomal recessive forms of severe combined immunodeficiency (SCID) among non-inbred populations. ADA deficiency can present in infancy, childhood, adolescence, or adulthood. Age of onset and severity is related to some 29 known genotypes associated with the disorder. It occurs…

Aetokthonotoxin (AETX) aka ‘eagle toxin’ discovered in 2021
Aetokthonotoxin (AETX), colloquially ‘eagle toxin’, was discovered in 2021 as the cyanobacterial neurotoxin causing vacuolar myelinopathy (VM) in eagles in North America. Avian vacuolar myelinopathy (AVM) is a fatal neurological disease that affects various waterbirds and raptors. It is most common in the bald eagle and American coot, and it is known in the killdeer, bufflehead, northern shoveler, American wigeon, Canada goose, great horned owl, mallard, and ring-necked duck.

Polish Cochineal (Porphyrophora polonica)
Polish cochineal (Porphyrophora polonica), also known as Polish carmine scales, is a scale insect formerly used to produce a crimson dye of the same name, colloquially known as “Saint John’s blood”. The larvae of P. polonica are sessile parasites living on the roots of various herbs—especially those of the perennial knawel—growing on the sandy soils of Central Europe and other parts of Eurasia. Before the development of aniline, alizarin, and other synthetic dyes, the insect was…
