These results strongly suggest that the signaling pathway from Fc receptors leading to expression of different genes important to leukocyte biology , initiates with tyrosine kinases and requires MAPK activation ; but in contrast to other tyrosine kinase receptors , FcR -mediated MAPK activation does not involve Ras and Raf .
