My research interests stem from my work as a graduate student in the laboratory of Dr. Jane Freedman (BUSM) and my work as a post-doctoral research fellow in the laboratory of Dr. Robert Flaumenhaft (BIDMC/HMS). I am primarily interested in the role that platelets play in the processes of hemostasis, thrombosis, and inflammation. In particular, I am fascinated by:
(1) The differential functions of platelet dense granules and alpha granules in thrombus formation and inflammation, respectively;
(2) The molecular mechanisms regulating packaging and secretion of platelet granules;
(3) The transcriptional control of thrombopoeisis; and
(4) The molecular mechanisms regulating platelet-bacteria interactions.
Most recently, I have been investigating the potential role of an RNA-binding protein - hematopoietic zinc finger (HZF) - in the synthesis and/or packaging of platelet alpha-granule proteins. In mice, HZF deficiency results in decreased platelet alpha granules, as well as absence of select alpha granules substances (Kimura et al, J Exp Med, 2002). In humans, a rare but serious bleeding disorder known as Gray Platelet Syndrome is associated with reduced or absent platelet alpha granules. It is our hope that elucidation of the molecular mechanisms underlying platelet granule formation will us better understand the etiology of Gray Platelet Syndrome and potentially other bleeding disorders.
