title: [Stimulation of the suppressor activity in relation to hematopoietic cells in the mouse thymus as affected by pertussis vaccine].
abstract: After a single intraperitoneal injection of formalinized whole-cell pertussis vaccine 5374 into CBA mice a drastic depletion of cells in the thymus accompanied by the enhancement of suppressor T-cells production is observed. T-cells inhibit the endogenous and exogenous colony-formation in the spleen by hematopoietic stem cells (CFUs). Treatment of thymus cells with the anti-I-Jk alloantiserum against a specific marker of suppressor T-cells in the presence of complement removes the inhibitory effect on CFUs proliferation and has a stimulatory action on the capacity of the marrow CFUs to form macroscopic hematopoietic colonies in the spleen compared with control ones. These results suggest probable involvement of I-J-bearing suppressor T-cells in the hematopoietic disorders induced by pertussis vaccine.
