Summary
This study proposes to investigate how white blood cells contribute to clotting that occurs in patients with an immune disorder called the Antiphospholipid Syndrome. This condition is more common than is generally known, and accounts for about one fifth of clots in the legs and about one third of strokes that occur in young people. It is also a common cause of miscarriages. The study focuses on how activation of the immune system, and inflammation interact to make certain white blood cells expre ....This study proposes to investigate how white blood cells contribute to clotting that occurs in patients with an immune disorder called the Antiphospholipid Syndrome.

Summary
CRP is a plasma marker that can identify individuals at high risk for heart attack and stroke. Our preliminary data suggests that plasma CRP is not only an innocent marker, but can also be activated and thereby become a strong inflammatory stimulus by changing from a five unit to a single unit form on the surface of activated platelets. We will investigate this CRP activation in vitro, in animal models and in patients, and aim to develop new drug therapies for diseases such as heart attack.
Regulation Of Insulin Sensitivity By Reactive Oxygen Species

Summary
In morbid obesity and type 2 diabetes chronic levels of reactive oxygen species (ROS) are detrimental and diminish insulin's ability to maintain normal blood glucose levels. Paradoxically, ROS also promote insulin action by inhibiting enzymes known as protein tyrosine phosphatases (PTPs). This proposal will determine whether the promotion of ROS for the inhibition of PTPs early in the progression of type 2 diabetes may be of therapeutic benefit.
