We recently demonstrated that chronic treatment with IL-1 beta induces coronary arteriosclerotic changes and vasospastic responses to autacoids in pigs in vivo and that those responses are importantly mediated by PDGF. The receptors for PDGF and other major growth factors

Previously, we have demonstrated that tyrosine phosphorylation of 78 and 92 kDa proteins in rat basophilic leukemia cells (RBL-2H3) is involved in a signal transduction system for high-affinity IgE receptor (Fc epsilon RI)-mediated histamine secretion. However, it is not clarified

Cardiovascular research, 32(6), 1131-1140 (1996-12-01)
Restenosis after percutaneous transluminal coronary angioplasty (PTCA) still remains a serious late complication. Many growth factors induced in restenotic lesions may be responsible for restenosis after PTCA. Most of the receptors for such growth factors possess tyrosine kinase activity. This

We examined the effect of the two protein tyrosine kinase inhibitors, alpha-cyano-3-ethoxy-4-hydroxy-5-phenylthiomethylcinnamide (ST638) and herbimycin A, on the activation processes of rat basophilic leukemia (RBL-2H3) cells by cross-linking of IgE receptors. RBL-2H3 cells sensitized with DNP-specific monoclonal IgE antibody were
