allows only those can recognize Foreign antigen bound to MHC

Positive selection

Positive selection allows only those can recognize Foreign antigen bound to ?

MHC

self peptide reaction -> apoptosis

MHC class II

IT IS CENTER OF ADAPTIVE immunity

CD4 (T helper) = MHC class II

Responsible for delayed hypersensitivity

CD4 (T helper)

responsible for CELL mediated effector mechanism

Th1 (T HELPER 1)

–regulation of ANTIBODY prod
