Development of suppressor T cells in mice heavily infected with mycobacteria.

abstract：:Acute and chronic infusions of a lipophilic analogue of cyclic AP (dibutyryl cyclic AMP) into cannulated afferent lymphatics of popliteal lymph nodes of sheep have reduced the output of both small and blast lymphocytes into efferent lymph and have tended to reduce the volume of efferent lymph flow (collected by chroni...
