Prenatal exposure to diazepam leads to a suppression of mitogen or allogen-induced lymphocyte proliferation as well as to a reduced production of tumour necrosis factor (TNF)-alpha from rat splenocytes during postnatal development of rats. We analysed the secretion of interleukin (IL)-6 which occurs at a later stage of the cytokine cascade. Splenocytes of male offspring from Long Evans rats, treated with a daily dose of diazepam (1.25 mg/kg) from gestational day 14 to 20, were stimulated with lipopolysaccharide (LPS) and concanavalin A (Con A). In response to LPS, IL-6 liberation was significantly lower in mixed splenocytes and spleen macrophages of 2 and 8 week old prenatally diazepam-treated rats than in controls. Spleen lymphocyte preparations of prenatally treated animals exhibited a reduction of IL-6 release at 12 h and an increase at 24 h of incubation. At 2 weeks of age, Con A-induced IL-6 production could only be detected in mixed splenocytes; prenatally treated rats were releasing significantly less IL-6 than controls. In 8 week old rats, IL-6 liberation from mixed splenocytes and spleen macrophages was significantly lower in prenatally treated animals than in controls. Spleen lymphocytes presented a complex response picture depending upon incubation conditions. Our data indicate that in prenatally diazepam-exposed rats, the disturbance of cytokine release also extends to cytokines which play an important role in the later phases of immune responses.
