Vindesine (VDS), a structural analogue of Vinca Alkaloids, was found to increase the NK-mediated cytolytic effects of mouse lymphocytes against human K562 target cells in an 18-hr assay. Pretreatment of effector or target cells with the drug did not affect substantially the NK reaction. The phenomenon has been detected using splenocytes of either congenitally athymic or conventional euthymic mice of different strains. Effector lymphocytes deprived of cells adherent to plastic surface or to nylon-wool column were still competent for drug-mediated increase of NK function. It is suggested that modification of the membrane make-up of effector or target cells reversibly induced by VDS, would promote higher NK-mediated cytolytic effects.
