T helper cells are white blood cells that are an essential part of the human immune system. They are often referred to as CD4 cells, T-helper cells or T4 cells. They are called helper cells nf en 12056 2 pdf one of their main roles is to send signals to other types of immune cells, including CD8 killer cells, which then destroy the infectious particle.
CD4 is a member of the immunoglobulin superfamily. D1 adopts an immunoglobulin-like β-sandwich fold with seven β-strands in 2 β-sheets, in a Greek key topology. CD4 interacts with the β2-domain of MHC class II molecules through its D1 domain. CD4 contains a special sequence of amino acids that allow it to recruit and interact with the tyrosine kinase Lck. HIV-1 uses CD4 to gain entry into host T-cells and achieves this through its viral envelope protein known as gp120.

HIV infection leads to a progressive reduction in the number of T cells expressing CD4. Medical professionals refer to the CD4 count to decide when to begin treatment during HIV infection, although recent medical guidelines have changed to recommend treatment at all CD4 counts as soon as HIV is diagnosed. A CD4 count measures the number of T cells expressing CD4. Viral load testing provides more information about the efficacy for therapy than CD4 counts. CD4 continues to be expressed in most neoplasms derived from T helper cells. T-cells play a large part in autoinflammatory diseases.
When testing a drug’s efficacy or studying diseases, it is helpful to quantify the amount of T-cells.
