Research Interests

Glycoprotein VI (GPVI) is a platelet-specific collagen receptor. When GPVI engages collagen, a signalling cascade is initiated, leading to platelet activation, aggregation, and thrombus formation.

In the injured vasculature, hyperactive platelets bind to exposed subendothelial collagen, forming thrombi that can detach and occlude near or distal vessels resulting in ischaemic heart disease or stroke. Therefore, controlling the activity of GPVI offers a way to control thrombosis.
