title: T suppressor afferent cells which regulate contact sensitivity to picryl chloride act across genetic barrier.
abstract: This paper investigates the requirement for genetic restriction in the action of T suppressor afferent cells (Ts-aff) which regulate the induction phase of contact sensitivity to picryl chloride. The results here reported show that Ts-aff which inhibit both the induction of contact sensitivity and DNA synthesis in the draining lymph nodes of sensitized mice, act across both H-2 and Igh genetic barrier and constitute new evidence which discriminates between two T suppressor cell populations in contact sensitivity.
