WebCD8+ T cells (often called cytotoxic T lymphocytes, or CTLs) are very important for immune defence against intracellular pathogens, including viruses and bacteria, and for tumour surveillance. When a CD8+ T cell recognises its antigen and becomes activated, it has three major mechanisms to kill infected or malignant cells. WebApr 15, 2013 · To execute these functions, CD8 (+) T cells must differentiate into CTLs, a process that is precisely regulated by a variety of cytokines, costimulatory molecules, and transcription factors.
