how do NK cells recognize and kill infected cells?-altered/absent MHC1 presentation -use cytotoxic granules (granzyme, perforin) which cells contribute to the anti-parasitic immune response-eosinophil -basophil degradation of pathogens occur only in the lysosomestrue toll-like receptors are always membrane boundtrue Naive T cells find and enter the secondary lymphoid tissues throughfollowing chemokine gradient as well as binding adhesion molecule at HEV TH17RORgammaT
