| Research Abstract |
Although periventricular leukomalacia (PVL) is one of the most common brain injuries in premature infants, there has been no effective treatment. We investigated the mechanism of PVL in relationship to microglia. We found that hematopoietic prostaglandin D synthase and microsomal prostaglandin E synthase were upregulated in glial cytoplasms in white matter of infant brains during hypoxic/ischemic (H/I) insults following maternal infection. We suggest that these prostaglandins may elevated the risk of PVL via microglial activation.
