Abstract: | Evidence is presented which demonstrates that the T lymphocytes which suppress humoral and cell-mediated immunity in CBA/H mice differ in the cell surface structures they express. The suppressor T cells of delayed-type hypersensitivity are Ly-1+, Ly-2? and Ia?, whereas the suppressor T cells of antibody formation are Ly-1?, Ly-2+ and Ia+. |
