Abstract

The influence of cigarette smoke on the humoral immune response of mice was investigated in lymphocytes derived from the spleen, bone marrow (BM) and mesenteric lymph nodes (MLN). Mice of the DBA/2J or C57BL/6 strain were exposed to cigarette smoke of a standard research cigarette, 2R1, twice a day, ten puffs each in morning and afternoon for 20, 40 or 60 weeks. At the end of the smoking period, animals were immunized intraperitoneally with the thymic independent antigens polyvinyl pyrrolidone (PVP) or trinitrophenyl (TNP)-Ficoll. The antibody responses were analyzed using sheep red blood cells coated with PVP or TNP, in a plaque forming cell (PFC) assay. The results indicate a statistically significant inhibition of the antibody response induced by PVP but not by TNP-Ficoll in splenic B cells of smoke exposed mice compared to sham controls. When tested in other lymphoid organs, there was higher anti-TNP PFC response from the BM and MLN cells of smoke exposed animals compared to sham controls.
