CD45antigen (Protein tyrosine phosphatase, receptor type, C also known as PTPRC and formerly known as leukocyte common antigen LCA)

Protein tyrosine phosphatase, receptor type, C also known as PTPRC is an enzyme that, in humans, is encoded by the PTPRCgene.[5] PTPRC is also known as CD45antigen (CD stands for cluster of differentiation), which was originally called leukocyte common antigen (LCA).[6] Function…

T helper cells (Th cells), also known as CD4+ cells or CD4-positive cells

The T helper cells (Th cells), also known as CD4+ cells or CD4-positive cells, are a type of T cell that play an important role in the adaptive immune system. They aid the activity of other immune cells by releasing cytokines.…

CD4

In molecular biology, CD4 (cluster of differentiation 4) is a glycoprotein that serves as a co-receptor for the T-cell receptor (TCR). CD4 is found on the surface of immune cells such as T helper cells, monocytes, macrophages, and dendritic cells. It was discovered in…

CD31

Platelet endothelial cell adhesion molecule (PECAM-1) also known as cluster of differentiation 31 (CD31) is a protein that in humans is encoded by the PECAM1gene found on chromosome17q23.3.[5][6][7][8] PECAM-1 plays a key role in removing aged neutrophils from the…

KIT (gene)

Proto-oncogene c-KIT is the gene encoding the receptor tyrosine kinase protein known as tyrosine-protein kinase KIT, CD117 (cluster of differentiation 117) or mast/stem cell growth factor receptor (SCFR).[5] Multiple transcript variants encoding different isoforms have been found for this gene.[6][7] KIT…

Cochineal

The cochineal (Dactylopius coccus) is a scale insect in the suborder Sternorrhyncha, from which the natural dye carmine is derived. A primarily sessile parasite native to tropical and subtropical South America through North America (Mexico and the Southwest United States), this insect lives…

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…

Armenian Cochineal (Porphyrophora hamelii)

The Armenian cochineal (Porphyrophora hamelii), also known as the Ararat cochineal or Ararat scale, is a scale insect indigenous to the Ararat plain and Aras (Araks) River valley in the Armenian Highlands and in Turkey. It was formerly used to produce an eponymous crimson carmine dyestuff known in Armenia as vordan karmir (Armenian: ŐžÖ€Ő€ŐĄŐ¶…
