(B) CD127-KLRG1 profiles of OTI cells transferred into CD11c-DNR transgene-negative hosts. 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. hassan opponent
