Effect of indomethacin on post-ischemic changes of CA1 neurons was studied in the hippocampus of the Mongolian gerbil. The gerbil was employed because due to poor development of posterior communicating artery ischemia could be easily induced in the forebrain simply by occluding bilateral common carotid arteries. Indomethacin (5 mg/kg, i.p.) was administered 30 min before the occlusion. The occl...
Microglia activated through Toll-like receptor (TLR)-2 or -4 can cause neuronal death by phagocytosing otherwise-viable neurons-a form of cell death called "phagoptosis." UDP release from neurons has been shown to provoke microglial phagocytosis of neurons via microglial P2Y6 receptors, but whether inhibition of this process affects neuronal survival is unknown. We tested here whether inhibitio...
BACKGROUND General anesthetics reduce neuronal death caused by focal cerebral ischemia in rodents and by in vitro ischemia in cultured neurons and brain slices. However, in intact animals, the protective effect may enhance neuronal survival for only several days after an ischemic injury, possibly because anesthetics prevent acute but not delayed cell death. To further understand the mechanisms ...
Stroke is the second leading cause of death and the primary cause of disability in humans. The phenomenon of ischemic tolerance perfectly describes the quote: “What does not kill you makes you stronger.’’ Ischemic preor postconditioning is actually the strongest known procedure to prevent or reverse delayed neuronal death. It works specifically in sensitive vulnerable neuronal populations, whic...
The hippocampal CA1 neurons are selectively vulnerable to global ischemia, and neuronal death occurs in a delayed manner. The threshold of global ischemia duration that induces neuronal death has been studied, but the relationship between ischemia duration and glial death in the hippocampal CA1 area has not been fully studied. We examined neuronal/glial viability and morphological changes in th...
