| Research Abstract |
Substance-P(SP) enhances whole blood coagulation through neurokinin-1 receptors(NK1R) in leukocytes while the precise mechanisms of this phenomenon remains to be established. Thus the effects of microparticles associated with tissue factor on monocyte-derived procoagulant activity provoked via SP : NK1R pathway were evaluated. CC chemokine ligand 5(CCL5) increased microparticles released from monocytes. SP enhanced CCL5-dependent release of microparticles from these cells. Forced expression of the full-length NK1R that is not constitutively expressed in monocytes also enhanced the release of microparticles from these cells.
