Effect of tamoxifen on pokeweed mitogen stimulated immunoglobulin secretion in vitro.
The influence of Tamoxifen on pokeweed mitogen induced immunoglobulin (Ig) secretion of human blood lymphocytes was tested in vitro. It was observed that pretreatment of T cell enriched preparations with "therapeutic" concentrations of Tamoxifen augmented their capacity to promote IgG but not IgM secretion of untreated autologous B-lymphocytes. Cultures containing Tamoxifen pretreated B cell enriched preparations and untreated T cells exhibited reduced secretion of both IgG and IgM.
