Did you know?
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. WebIn our study, the elevated expression of CD39 in CD4+/CD8+ T cells were significantly associated with the pathological T stage (pT < 2, P = 0.041) and papillary tumor ( P = 0.038). Moreover, the CD8+CD39+ T cells showed a stronger tumor-killing effect and produced a higher level of IFN-γ than other T cell populations.
