Integrin-linked kinase regulates the rate of platelet activation and is essential for the formation of stable thrombi.

J. Thromb. Haemost. 12(8) , 1342-52, (2014)

Integrin-linked kinase (ILK) and its associated complex of proteins are involved in many cellular activation processes, including cell adhesion and integrin signaling. We have previously demonstrated ...

Platelet function tests, independent of platelet count, are associated with bleeding severity in ITP.

Blood 126 , 873-9, (2015)

Immune thrombocytopenia (ITP) patients with similarly low platelet counts differ in their tendency to bleed. To determine if differences in platelet function in ITP patients account for this variation...

Procoagulant platelets form an α-granule protein-covered "cap" on their surface that promotes their attachment to aggregates.

J. Biol. Chem. 288(41) , 29621-32, (2013)

Strongly activated "coated" platelets are characterized by increased phosphatidylserine (PS) surface expression, α-granule protein retention, and lack of active integrin αIIbβ3. To study how they are ...
