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.

Web摘要. We have constructed a helper cell line and vector system based on the Bryan high titer (BH) strain of Rous sarcoma virus (RSV). BH-RSV is a defective virus which lacks an env gene; however, if env is supplied in trans, it replicates to a very high titer. Like BH-RSV, the vector contains gag and pol genes and lacks an env gene. WebAdoptive transfer assays with purified subpopulations of the lymphocytes that mediated this effect showed that W3/25+ T cells of the helper/inducer subclass, when injected alone, failed to restore rejection, and were also able, when injected with normal LNC or the W/25+ cells separated from them, to prevent these cells from effecting rejection.

CD4 Cells Function in the Immune System WebThe HIV attaches to CD4 molecule and CCR5 (a chemokine co-receptor), the virus surface fuses with the cellular membrane which allows it entry into a T-helper lymphocyte. After integrating with the host genome the HIV provirus forms followed by transcription and the production of viral mRNAs.

WebSince at least 1997, CDC has required the detection of both CD3+ and CD4+ to identify T4 helper cells, because the CD3 marker is needed to identify T-cell .
