Neuronal PPARgamma deficiency increases susceptibility to brain damage after cerebral ischemia.

ABSTRACT: Peroxisome proliferator-activated receptor gamma (PPARgamma) plays a role in regulating a myriad of biological processes in virtually all brain cell types, including neurons. We and others have reported recently that drugs which activate PPARgamma are effective in reducing damage to brain in distinct models of brain disease, including ischemia. However, the cell type responsible for PPARgamma-mediated protection has not been established. In response to ischemia, PPARgamma gene is robustly upregulated in neurons, suggesting that neuronal PPARgamma may be a primary target for PPARgamma-agonist-mediated neuroprotection. To understand the contribution of neuronal PPARgamma to ischemic injury, we generated conditional neuron-specific PPARgamma knock-out mice (N-PPARgamma-KO). These mice are via
