Research Interests:

 

We have been involved in work leading to molecular mechanism of platelet activation which is crucial to understanding the cell membrane receptors and the mechanisms of agonist-mediated signal transduction pathways in platelet activation, leading to better medications to prevent heart attacks and strokes.

 

Thrombin, generated at the site of vascular damage by extrinsic and intrinsic coagulation cascades, is an important agonist for platelet activation, yet the signal transduction mechanisms involved in thrombin-mediated human platelet fibrinogen receptor activation are yet to be elucidated.  Thus, we are focused on characterizing the signaling requirements that mediate platelet activation by thrombin and thrombin receptor-activating peptides to better understand hemostasis and thrombosis.

 

Protein kinase B (PKB/Akt) is a serine-threonine kinase that has been established as an important signaling intermediate in regulating cell survival, cell cycle progression, as well as agonist-induced platelet activation.  We have shown that Gi-coupled P2Y12 ADP receptor is responsible for a significant proportion of activation of Akt in platelets.  We are now further elucidating the signaling events involved in Akt activation and its role in platelet activation mediated by various agonists in human and mouse platelets.

 

We are also examining the role of Src family kinases in signal transduction mechanisms in platelets.
