title: Selective enhancement of synthesis of interleukin-2 in lymphocytes in the presence of ciprofloxacin.
abstract: A study was performed to verify the effect of ciprofloxacin on the production of interleukin-2 and other cytokines in cultures of human peripheral lymphocytes. In the presence of ciprofloxacin, lymphocytes demonstrated increased synthesis of interleukin-2 (100-fold, 7-fold and 1.5-fold increase at ciprofloxacin concentrations of 80, 20 and 5 micrograms/ml respectively), as measured by radioimmunoassay. Synthesis of other cytokines from T lymphocytes, gamma-interferon, lymphotoxin and granulocyte-macrophage colony stimulating factor as well as interleukin-1 and tumour necrosis factor from monocytes was not increased, but inhibited at a ciprofloxacin concentration of 80 micrograms/ml. Thus the effect of ciprofloxacin resulting in enhanced synthesis of interleukin-2 seems to be specific.
