title: [The influence of 6-mercaptopurine on the humoral immune response in guinea pig. 1. The importance of antigen and adjuvans (author's transl)].
abstract: Following an intradermal immunization of guinea pigs with dinitrophenylated bovine gamma globulin (DNP23-BGG), human serum albumin (HSA) and trinitrophenylated sheep red blood cells (TNP-SRBC) emulsified in complete or in incomplete Freund's adjuvans the effectivity of 6-mercaptopurine (6-MP) on the formation of specific antibodies was investigated. By application of 10 mg 6-MP/kf/day--in guinea pigs a significant depression of antibody formation against BGG could be demonstrated if treatment is started on the day of antigen injection and continued for seven days. The production of anti-SRBC agglutinating antibodies was only suppressed if the antigen was injected together with complete Freund's adjuvans. The anti-DNP and anti-HSA antibody formation was not influenced by this kind of immunosuppressive treatment.
