DURING investigations of the effects of induced immune paralysis on delayed hypersensitivity in vivo and in vitro, evidence has been found1,2 for a diffusible factor which is released from the sensitive cells in contact with the antigen; this factor inhibits migration of cells from a normal lymph node explant. These investigations have been extended and the results will be summarized here.
