Microglia, the major immune effector cells in the CNS, become activated when the brain suffers injury. In this study, we observed that prothrombin, a zymogen of thrombin, induced NO release and mRNA expression of inducible NO synthase, IL-1beta, and TNF-alpha in rat brain microglia. The effect of prothrombin was independent of the protease activity of(More)
We have shown that prothrombin kringle-2 (pKr-2), a domain of human prothrombin distinct from thrombin could activate cultured rat brain microglia in vitro. However, little is known whether pKr-2-induced microglial activation could cause neurotoxicity on dopaminergic (DA) neurons in vivo. To address this question, pKr-2 was injected into the rat substantia(More)
c-Jun N-terminal kinase (JNK) is activated by cellular stress and plays critical roles in diverse types of cell death. However, role of JNK in beta-cell injury is obscure. We investigated the role for JNK in streptozotocin (STZ)-induced beta-cell death. STZ induced JNK activation in insulinoma or islet cells. JNK inhibitors attenuated insulinoma or islet(More)
The U. S. Department of Energy (DOE) is working with private industry to develop highly advanced coal-fired power generation systems that will have significantly higher thermal efficiency, superior environmental performance, and a lower cost of electricity than current coal-fired power plants. The goal of the DOE advanced power generation program is to(More)
