the adoptive transfer of delayed-type hypersensitivity ( dth ) into naive recipients requires the interaction of two functionally distinct ly-1+ t cells : and i-j- cell effector cell for dth which transfers antigen-specific dth only into animals whose suppressive mechanisms have been compromised , and and i-j+ cell which alone never transfers dth but allows the transfer of dth by the i-j- dth effector cell into naive animals .
