Question

Quizplus · Accepted Answer

Each T-cell receptor is specific to a single antigen. T cells recognize antigens only when presented by MHC molecules, and each T-cell receptor is specific to a particular antigen-MHC complex. T cells do not increase their diversity through somatic mutation, unlike B cells. T cells are not nonspecific; they recognize specific antigens presented by MHC molecules.
