Research activity encompasses fundamental aspects of transmembrane signaling in human platelets, including small GTP-binding proteins, tyrosine kinases and adhesion receptors.
Specific area of interest include:
- Mechanisms of blood platelets aggregation
- Signal transduction through platelet integrins alpha2beta1 and alphaIIbbeta3
- Role of the purinergic receptor P2Y12 in regulation of platelet function
- Mechanisms regulating inositol phospholipids metabolizing enzymes
phospholipase C and phosphatidylinositol 3-kinase
- Protein-tyrosine kinases and cellular function
- Function and regulation of the ras-related small GTPases Rap1 and Rap2
- Analysis of the biochemical abnormalities of platelets in familiar
macrothrombocytopenic syndromes
- metabolism and funcion of amyloid precursor protein: blood platelets as a
cellaulr model for neurodegenerative disorders

Project Title:
Role of the tyrosine kinase Pyk2 in platelet activation

The research project is aimed to define the role the focal adhesion kinase Pyk2 in platelet function and thrombus formation, in order to verify whether this protein might represent a potential target for anti-platelet treatmentsin cardiovascular diseases. We will take advantage from the analysis of a recently generated transgenic mice strain lacking Pyk2. The project proposes an extensive ex vivo functional analysis on isolated platelets from Pyk2 KO mice, in order to clarify the role of this kinase in integrin-mediated platelet adhesion, as well as in agonist-induced platelet secretion and aggregation, and a comprehensive investigation of the activated intracellular signaling pathways to unravel the molecular dynamics of Pyk2 involvement in platelet functionality.
