<prompt> True about MHC-class II -Not involved in innate immunityCytotoxic T-cell involvedPresent in nucleated cellsAll  <response>: Ans. is a i.e., NOT involved in innate immunity o MHC I and II are pa of adapative immunity. Major function of MHC molecule is to present the antigen to T cell that is pa of adaptive immunity. o Cytotoxic T cells are MHC - class I restricted. o MHC class II complex is found only on cells of the immune system class I is found on all nucleated cells and platelets. o B cells have both MHC class I and II complexes.
