Cytolytic cd8+ t cell
WebCytolytic CD8 T cells play a crucial role in the control and elimination of virus-infected cells and are a major focus of HIV cure efforts. However, it has been shown that HIV-specific CD8 T cells are infrequently found within germinal centers (GCs), a predominant site of active and latent HIV infection. WebActivation of human CD8 Treg resulted in rapid cytolysis of pathogenic CD4 T cells as one mechanism of action. Upon the addition of CD8 Treg modulators, activation, and prevalence of CD8 Tregs increased along with the increase of degranulation and lytic molecules, and the death of antigen activated CD4 T cells.

CD8 + T cells are recognized as T C cells once they become activated and are generally classified as having a pre-defined cytotoxic role within the immune system. However, CD8 + T cells also have the ability to make some cytokines, such as TNF-α and IFN-γ, with antitumour and antimicrobial effects.
