data suggest that activation of a tyrosine kinase system is an early response to the binding of g-csf , gm-csf , tnf , or ifn to their respective cell surface receptors , or to the addition of dimethyl sulfoxide , and that the resulting phosphorylation event ( s ) may play a role in securing common elements in the biologic responses to these agents .
