One of the major differences between the T-cell receptor and antibody is that the T-cell receptor is not secreted. Another major difference is that the T-cell receptor only binds to antigen which is presented on MHC proteins. Another way of saying that is that T-cells only recognize antigen when it is presented.ne of the major differences between the T-cell receptor and antibody is that the T-cell receptor is not secreted.
