title: Effect of kanglemycin C on lymphokin a production and gene expression of mouse splenocyte and macrophage.
abstract: OBJECTIVE
  To study the effect of kanglemycin C (KC) on production and gene transcription of lymphokins.
  
  
  METHODS
  Cell proliferation and lymphokin activities were quantified with MTT colorimetry and ELISA, and gene transcriptions of lymphokins semi-quantified with RT-PCR.
  
  
  RESULTS
  Suppression of KC on proliferation of enriched T-and B-cell respectively mediated by Con A and LPS was declined by addition of exogenous IL-1, IL-2, and IL-6. KC 80 nmol/L markedly inhibited IL-2 and IL-6 production and mRNA transcription of incubated mouse splenocytes induced by Con A. Additionally, KC had some suppression on IL-1beta and IL-6 productions of peritoneal macrophage stimulated by LPS (5microg/mL), whereas cyclosporine (CS) had not.
  
  
  CONCLUSIONS
  Immunosuppression of KC came true partially through the decrease of IL-1beta, -2 and -6 productions, especially of IL-2. However, CS's immunosuppression was mainly through the decrease of IL-2 production.
