WebApr 5, 1999 · Cytotoxic T Lymphocyte–associated Antigen 4 (CTLA-4) Can Regulate Dendritic Cell–induced Activation and Cytotoxicity of CD8+ T Cells Independently of … WebNK cells are a kind of lymphocyte that can attack other cells without being primed first. One of the ways they do this is by looking for self MHC-I on the surface of a cell. If the cell has self MHC-I, it inhibits the NK cell and stops it attacking. Otherwise, if there is no MHC-I, the NK cell is not inhibited and lyses the target cell.
