Abstract
The effects of amphotericin B, 5-fluorocytosine, and the combination of both drugs on lymphocyte function in vitro were investigated. Amphotericin B, alone or in combination with 5-fluorocytosine, significantly suppressed both spontaneous lymphocyte transformation and the response of lymphocytes to stimulation with streptokinase-streptodornase. 5-Fluorocytosine had no effect on spontaneous or antigen-induced transformation. Lymphocyte responses to the mitogens phytohemagglutinin and concanavalin A were not changed by exposure to amphotericin B, 5-fluorocytosine, or the combination of both drugs. T-lymphocyte receptors for sheep erythrocytes and B-lymphocyte surface immunoglobulin and receptors for complement were not changed by treatment with amphotericin B or 5-fluorocytosine.
