ABSTRACT
N-formyl-methionyl-leucyl-phenylalanine (fMLP) a potent chemotactic peptide stimulates immune responses by activating macrophages and other cells of the immune system. The present study reports inhibition of fMLP-induced activation of murine peritoneal and P388D-1 macrophage cell line by protein kinase C (PKC) inhibitors, H-7 and chelerythrine chloride. Similarly, tumoricidal activity was also downregulated by protein tyrosine kinase (PTK) inhibitors genestein and lavendustin A. Further, fMLP increased tyrosine phosphorylation of several proteins in murine macrophages, which were inhibited in presence of genestein and lavendustin A. These findings suggest the involvement of PKC and PTK in the activation of murine macrophages with fMLP.
