title: The effects of cyclosporin A on the early responses of B and T cells to Epstein-Barr virus infection.
abstract: The immunosuppressive properties of the fungal metabolite Cyclosporin A (CsA) on the human lymphocyte response to the polyclonal B cell activator Epstein-Barr virus (EBV) in vitro were assessed. CsA showed both stimulatory and inhibitory effects on EBV-induced IgM secretion, the net effect being dependent on the dose of virus used. T cells were required for both these effects to occur. A model is proposed to account for the complex interactions of CsA in this system.
