Targeting cytotoxic T-lymphocyte antigen-4 (CTLA-4)

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. WebDec 21, 1999 · One general form of therapy that might be a useful adjunctive treatment is immunotherapy.
