    Their key effector cytokine is IL-10. Their main effector cells are NK cells as well as CD8 T cells, IgG B cells, and IL-10 CD4 T cells. The key THαβ transcription factors are STAT1 and STAT3 as well as IRFs. IL-10 from CD4 T cells activate NK cells' ADCC to apoptose virus-infected cells and to induce host as well as viral DNA fragmentation ...

    en.wikipedia.org/wiki/Naive_T_cell

    In immunology, a naive T cell (T h 0 cell) is a T cell that has differentiated in the thymus, and successfully undergone the positive and negative processes of central selection in the thymus. Among these are the naive forms of helper T cells ( CD4 + ) and cytotoxic T cells ( CD8 + ).

    T-cells play a large part in autoinflammatory diseases. [25] When testing a drug's efficacy or studying diseases, it is helpful to quantify the amount of T-cells on fresh-frozen tissue with CD4+, CD8+, and CD3+ T-cell markers (which stain different markers on a T-cell – giving different results). [26]

    Optimal CD8 + T cell response relies on CD4 + signalling. [44] CD4 + cells are useful in the initial antigenic activation of naive CD8 T cells, and sustaining memory CD8 + T cells in the aftermath of an acute infection. Therefore, activation of CD4 + T cells can be beneficial to the action of CD8 + T cells. [45] [46] [47]

    The CD8 + T cell response is thought to be important in controlling virus levels, which peak and then decline, as the CD4 + T cell counts rebound. A good CD8 + T cell response has been linked to slower disease progression and a better prognosis, though it does not eliminate the virus. [3] During the acute phase, HIV-induced cell lysis and ...

    a co-receptor (with TCR, T-cell receptor) for MHC Class I; mostly found on cytotoxic T cells, but also on natural killer cells, cortical thymocytes, and a subset of myeloid dendritic cells. In HIV infection, CD8 + cytotoxic T cells recognise and kill infected CD4 + helper T cells, which are critical for the
