Genetic And Histological Alterations Reveal Key Role Of Prostaglandin Synthase And Cyclooxygenase 1 And 2 In Traumatic Brain Injury–Induced Neuroinflammation In The Cerebral Cortex Of Rats Exposed To Moderate Fluid Percussion Injury, Hideki Shojo, Cesar V. Borlongan, Tadashi Mabuchi

Neurosurgery and Brain Repair Faculty Publications

After the initial insult in traumatic brain injury (TBI), secondary neurodegeneration occurs that is intimately associated with neuroinflammation. Prostaglandin (PG) synthases and cyclooxygenase (COX) 1 and 2 may contribute to inflammation in the brain. Temporal and spatial expression features of PG and COX1 and 2 following trauma may guide the development of antineuroinflammation strategies. Here, we examined PG synthase signaling and COX1 and 2 gene expression levels and COX-1- and 2-positive cell types and their temporal localization in TBI-induced brain in an effort to reveal their participation in the disease’s evolving neuroinflammation. Using brain samples from the cerebral cortex of …
