Wolf Szmuness, epidemiologist and former roommate of a future Pope John Paul II, is named in an AIDS origin theory involving his hepatitis B vaccine trials
Wolf Szmuness (1919 – 1982) was a Polish-born epidemiologist who emigrated to and worked in the United States. He conducted research at the New York Blood Center and, from 1973, he was director of the Center’s epidemiology laboratory. He designed and conducted the trials for the first vaccine to prove effective against hepatitis B. European beginnings Szmuness was born in Warsaw, Poland on 12 March 1919.…

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.…

In the case of GVHD, maculopapular rash may progress to a condition similar to toxic epidermal necrolysis (TEN)
Together with Stevens–Johnson syndrome (SJS) it forms a spectrum of disease, with TEN being more severe. Early symptoms include fever and flu-like symptoms. A few days later the skin begins to blister and peel forming painful raw areas. Mucous membranes, such as the mouth, are also typically involved. Complications include dehydration, sepsis, pneumonia, and multiple organ failure. The most common cause is certain medications such as lamotrigine, carbamazepine, allopurinol, sulfonamide…

Erich Traub (1906 – 1985) German veterinarian, scientist and virologist who specialized in foot-and-mouth disease, Rinderpest and Newcastle disease
Erich Traub worked directly for Heinrich Himmler, head of the Schutzstaffel (SS), as the lab chief of the Nazis’ leading bio-weapons facility on Riems Island. Note: Riems is home to the oldest virological research institution in the world, now called the Friedrich Loeffler Institute, which was built by Friedrich Loeffler in 1910. Loeffler, a professor at the University of Greifswald, ran filtration tests in 1898 and found…

Ommochrome (visual pigment) and Kynurenine (a metabolite of the amino acid l-tryptophan used in the production of niacin)
Ommochrome (or visual pigment) refers to several biological pigments that occur in the eyes of crustaceans and insects. The eye color is determined by the ommochromes. Ommochromes are also found in the chromatophores of cephalopods, and in spiders. Ommochromes are metabolites of tryptophan, via kynurenine and 3-hydroxykynurenine. They are responsible for a wide variety of colors, ranging from yellow over red and brown to black. Lighter colors tend to be generated by ommatins,…

Streptomyces is the largest antibiotic-producing genus, producing antibacterial, antifungal, and antiparasitic drugs, and also a wide range of other bioactive compounds, such as immunosuppressants.
Streptomyces is the largest genus of Actinomycetota, and the type genus of the family Streptomycetaceae. Over 700 species of Streptomyces bacteria have been described. As with the other Actinomycetota, streptomycetes are gram-positive, and have very large genomes with high GC content. Found predominantly in soil and decaying vegetation, most streptomycetes produce spores, and are noted for their distinct “earthy” odor that results from production of a volatile metabolite, geosmin. Different strains of the…

Sterol carrier proteins (aka nonspecific lipid transfer proteins)
These proteins are different from plant nonspecific lipid transfer proteins but structurally similar to small proteins of unknown function from Thermus thermophilus. This domain is involved in binding sterols. The human sterol carrier protein 2 (SCP2) is a basic protein that is believed to participate in the intracellular transport of cholesterol and various other lipids. Human…

HLA-B major histocompatibility complex, class I, B
HLA-B (major histocompatibility complex, class I, B) is a human gene that provides instructions for making a protein that plays a critical role in the immune system. HLA-B is part of a family of genes called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body’s own proteins from proteins made by foreign invaders such as viruses and bacteria. HLA is…

HLA-A
Further information: Human leukocyte antigen and History and naming of human leukocyte antigens HLA-A is a group of human leukocyte antigens (HLA) that are encoded by the HLA-A locus, which is located at human chromosome 6p21.3.[1] HLA is a major histocompatibility complex (MHC) antigen specific to humans. HLA-A is one of three major types of human MHC class I transmembrane proteins. The others are HLA-B and HLA-C.[2] The protein is a heterodimer,…
