Before Moving on…. BLOOD…..!!! CD 8 cells • CD8 T cells, also known as cytotoxic T cells, • Vital part of the immune system's defense against infections and cancer. • Equipped with T-cell receptors (TCRs) on their surface, CD8 T cells can recognize specific antigens presented by infected or abnormal cells. • Once activated, they transform into cytotoxic T lymphocytes (CTLs) capable of directly killing these target cells. • CD8 T cells also have the ability to form long-lived memory cells, providing rapid and robust immune responses upon re-exposure to previously encountered pathogens. • Their role in viral infections and cancer immunotherapy makes them crucial components of adaptive immunity.
