title: Stimulation of thymus cells by the calcium ionophore A23187 in the presence of LPS and 2-ME: on the mode of action of A23187 and 2-ME.
abstract: The stimulation of murine spleen and thymus cells by the calcium ionophore A23187 was studied using a serum-free culture technique. In cultures of spleen cells, rabbit IgG was capable of replacing A23187 in bringing about the stimulation of cells. Low concentrations of A23187 were inhibitory to proliferating B lymphocytes. In cultures of thymus cells a stimulating activity of A23187 was observed only if LPS was present in the medium.
