Platelet Proteomics
Platelets are small anucleate cells that circulate in the blood playing a central role in haemostasis, helping to heal any vascular damage by forming a vascular plug. Pathologically, platelet activation underlies thrombotic and heart disease, now recognised as the biggest killer of mankind in the western world.
The Platelet Proteomics group, led by Prof. Ángel García, is also part of the Instituto de Investigación Sanitaria de Santiago (IDIS) [Santiago Health Research Institute]. In our group, we are currently using a combination of proteomics technology and classical biochemistry to unravel the signal transduction events following the activation of the most relevant platelet receptors. We are focusing our studies on healthy and diseased platelets in order to identify novel biomarkers and drug targets that may help to treat / diagnose those diseases where unwanted platelet activation plays a role, such as acute coronary syndromes. In addition, we are currently searching for small molecule inhibitors of some of the most interesting targets identified by proteomics. We are also studying extracellular vesicles as a source of biomarkers in platelet-related diseases.

Líneas de investigación
Our research focus on the study of platelets and extracellular vesicles in those pathologies where an unwanted platelet activation plays a role, such as obesity and coronary artery disease. This is done by a combination of proteomic and functional approaches. The aim is to investigate platelets at molecular level to identify novel biomarkers and drug targets that may help to treat/diagnose atherothrombosis. Potential drug targets identified by proteomics are being investigated since a pharmacological point of view to find small molecules that can inhibit/modulate them.
