The cloned interleukin-3 dependent cell line, M1-A5 was studied to determine whether protein kinase C, calcium mobilization, and 5-lipoxygenase activity were involved in the signal transduction pathways required for the production of TNF. TNF release was stimulated by 10 ng/ml phorbol myristate acetate (PMA), 2 microM calcium ionophore A23187, and 1 microgram/ml lipopolysaccharide (LPS) with synergism seen between PMA and A23187. All signals were blocked by phloretin and the PMA signal was… CONTINUE READING
