WebCytotoxic T lymphocyte antigen-4 (CTLA-4) is a transmembrane protein expressed on T regulator cells. CTLA-4 is a negative regulator of T cell activation. CTLA-4 binds markers on antigen presenting cells (APC) including B7, which functions as an immune check point to down regulate the immune response. 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.
