MHC: antigen complex inozivikanwawo neCD4 co-receptor ye helper cell, iyo inoshandisa ma molecules mukati me T cell (semuenzaniso, Lck) ayo anokonzeresa T cell's activation. Helper T cells ane kushamwaridzana kwakaderera neMHC: antigen complex kupfuura kuonekwa kweT killer cells, zvichireva kuti ma receptors akawanda (anenge 200<unk>300) pane helper T cell inofanira kusungwa neMHC: antigen kuitira kuti ishande helper cell, nepo killer T cells inogona kumisikidzwa nekubatana kweimwe MHC: antigen molecule. Helper T cell activation inodawo nguva yakareba yekubatana neantigen-inoratidzira activation. Kugadzirwa kweCD4 co-receptor yemubatsiri cell, iyo inoshandura mamorekuru mukati meT cell (semuenzaniso, Lck) ayo anokonzeresa T cell's activation. Mubatsiri T cells ane kushamwaridzana kwakaderera neMHC: antigen complex kupfuura kunoonekwa kune killer T cells, zvinoreva kuti ma receptors akawanda (anenge 200<unk>300) pane helper T cell
Kirasi II MHC mamorekuru
