Refers to the fact that a given T cell will recognize a peptide antigen only when it is bound to a host body's own MHC molecule. Normally, as T cells are stimulated only in the presence of self-MHC molecules, antigen is recognized only as peptides bound to self-MHC molecules.

Thank you Slight Smile So it is restricted in the sense that it won't target self antigens, and will recognize foreign antigens only when bound to MHC and nothing else?
