Image of CD4 co-receptor binding to MHC (Major Histocompatibility Complex) non-polymorphic region. 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 helper T cells, monocytes, macrophages, and dendritic cells.
A congenital disorder of glycosylation (previously called carbohydrate-deficient glycoprotein syndrome) is one of several rare inborn errors of metabolism in which glycosylation of a variety of tissue proteins and/or lipids is deficient or defective. Congenital disorders of glycosylation are sometimes known as CDG syndromes.
the platelet Glycoprotein Ib/V/IX complex. Expressed on platelets and is a late, specific marker of megakaryocyte differentiation. The Glycoprotein Ib/V/IX complex is essential for normal haemostasis; deficiency results in Bernard-Soulier Syndrome, a syndrome of thrombocytopenia and giant platelets. CD42a
As well as being involved in forming a complex with MHC-II with TCR to control T-cell fate, the CD4 receptor is infamously the primary receptor that HIV envelope glycoprotein GP120 binds to. [6] In comparison, CD28 acts as a ‘co-coreceptor’ (costimulatory receptor) for the MHC-II binding with TCR and CD4. CD28 increases the IL-2 secretion ...
The depletion of CD4 T cells and the development of chronic inflammation are signature processes in HIV pathogenesis that propel progression to acquired immune deficiency syndrome (AIDS). CD4 T cell depleted to the cell count of less than 200cell/μL in blood during AIDS allows various pathogens to escape T cell recognition, thus allowing ...
Azealia Banks is threatening to take her feud with Matty Healy to court.. The rapper demanded $1 million and a public apology from The 1975 band member in a cease-and-desist letter shared via X in ...
CD4 immunoadhesin was first developed in the mid-1990s as a potential therapeutic agent and treatment for HIV/AIDS. The protein is a fusion of the extracellular domain of the CD4 receptor and the Fc domain of human immunoglobulin G (IgG), the most abundant antibody isotype in the human body. [1]
"The mystery has finally been solved," Congo's health ministry says, after an unidentified disease outbreak started killing mainly women and children in a remote region.
