AIM: To investigate the effect of PD98059, a specific repressor of extracellular signal regulated kinase1/2 (ERK1/2), on the proliferation of the murine lymphocytes. METHODS: Lymphocytes were isolated from lymphoid nodes of BALB/c mouse. After stained with carboxy fluorescein diacetate, succinimidyl ester, the cells were stimulated with polyclonal activators, concanavalin and phorbol 12,13 dibutyrate plus ionomycin.
