The role of cytoskeleton and protein phosphorylation in concanavalin A and phorbol ester (PMA) induced mast cell secretion was investigated. It was shown that the receptor coupled with lectin interacts with the cytoskeleton. When the ligand-receptor complex is formed, an increased phosphorylation of some proteins is induced. The same proteins are phosphorylated under the influence of PMA, a protein kinase C activator, thus suggesting that protein kinase C is involved in the regulation of mast cell exocytosis. The results obtained testify to the effect that the mechanism of mast cell degranulation induced by concanavalin A is due to modification of the cytoskeleton. 相似文献
