| Abstract: | The authors studied the influence of the DNA and RNA inhibitors on the formation of antibody-forming cell populations in induction of a secondary immunological response in vitro. Low concentrations of cytosine-arabinoside, the DNA synthesis inhibitor, increased the count of indirect hemolysin-forming and rosette-forming cells; its high concentrations depressed the secondary immunological response induction in the direct hemolysin-forming cell system more intensively than in the indirect cell system. Actinomycin D depressed the stimulation of secondary immunological response in vitro both in the systems of direct and indirect hemolysin-forming, and of rosette-forming cells. |
