Biography

Current Research

Stroke is a potentially devastating neurological disorder with high morbidity and mortality.Thrombolytic agents such as tissue plasminogen activator (t-PA) are currently the only drugs available to reverse acute ischemic stroke, but paradoxically reestablishing of circulation by t-PA may initiate reperfusion injury.Therefore,treatmentsthat can limit reperfusion injury are urgently needed.Studies using mouse genetics, experimental stroke models, and selective peptide inhibitors and activators have implicated protein kinase C delta in stroke-induced reperfusion injury, in particular PKC delta expressed in neutrophils (Chou et al., 2004 JCI; Chou & Messing 2005Trends Cardiovasc Med).Understanding the molecular and cellular actions of PKC delta in reperfusion injury requires the identification of the unique targets of PKC delta in signaling pathways activated by ischemia and reperfusion.We have identified several direct substrates of PKC delta using a novel chemical-genetic approach, and are currently characterizing the roles of these PKC delta substrates in stroke-reperfusion injury.
