Research Abstract

Extracellular acidification caused Ca oscillation via activation of NHE1 in reverse mode and subsequently phosphorylated CaMKII. Phosphorylated CaMKII translocated into nuclei and phosphorylated CREB, leading to initiation of gene transcription. In rat or mouse middle cerebral artery occlusion model, brain pericytes migrated into peri-infarct areas. They expressed CREB and secreted a variety of nerve growth factors, indicating that pericytes may play a neuroprotective role during brain ischemia.
