Abstract
The effect of suppressor cells on formation of effector cells was studied by comparing the development of DNCB [dinitrochlorobenzene] contact sensitivity in cyclophosphamide-treated (suppressor cells eliminated) and nontreated (suppressor cell containing) guinea-pigs. From experiments in 4 different models of generation of effector cells the following conclusions were drawn: impulses activating the formation of effector cells activate suppressor cells; under conditions of conventional immunization, suppressor cells are activated later than effector cells and elimination of suppressor cells results in an increase in intensity and duration of specific skin reactions.
