WebJun 17, 2024 · CD4 + and CD8 + T cells participate in cellular immunity. The former, also known as helper T lymphocytes, assist humoral and cellular immunity. The latter, also known as cytotoxic cells, kill target cells ( 7 ). Most tumor cells express antigens that mediate the recognition of CD8 + T cells. WebAug 8, 2024 · Central memory T cells (CD8_CM), terminal effector T cells (CD4_TE and CD8_TE), and effector memory T cells (CD8_EM) were all characterized by low levels of naïve markers. However, the expression of cytotoxic markers ( NKG7 , GNLY , PRF1 , GZMK , and GZMH ) was low in CD8_CM and CD8_EM but high in CD4_TE and CD8_TE.
