Role of melatonin receptors in the effect of estrogen on brain edema, intracranial pressure and expression of aquaporin 4 after traumatic brain injury
Objective(s): Traumatic brain injury (TBI) is one of the most common causes of death and disability in modern societies. The role of steroids and melatonin is recognized as a neuroprotective factor in traumatic injuries. This study examined the role of melatonin receptors in the neuroprotective effects of estrogen. Materials and Methods: Seventy female ovariectomized Wistar rats were divided in...
متن کاملEffects of mannitol on hypoxic-ischemic brain edema and aquaporin-4 expression in neonatal rats
Brain edema after hypoxic-ischemic brain damage (HIBD) is a serious problem in neonates. Mannitol can mitigate edema; however, the molecular mechanism has not been fully elucidated. It has been reported that aquaporin-4 (AQP4), a member of the water channel protein family, plays a vital role in the development of brain edema. We therefore investigated whether mannitol might alleviate brain edem...
متن کاملDelayed onset of brain edema and mislocalization of aquaporin-4 in dystrophin-null transgenic mice.
Cerebral water accumulation was studied during induction of brain edema in dystrophin-null transgenic mice (mdx-betageo) and control mice. Immunofluorescence and immunoelectron microscopic analyses of dystrophin-null brains revealed a dramatic reduction of AQP4 (aquaporin-4) in astroglial end-feet surrounding capillaries (blood-brain barrier) and at the glia limitans (cerebrospinal fluid-brain ...
متن کاملInteractions of connexin 43 and aquaporin-4 in the formation of glioma-induced brain edema.
Connexin 43 (Cx43) and aquaporin-4 (AQP4) have important roles in the formation of glioma-induced brain edema; however, the association between these two factors in the development of edema has remained to be elucidated. In the present study, immunofluorescence and western blot analysis revealed that in a rat model of intracranial C6 glioma, Cx43 expression levels were low to undetectable and A...
متن کاملExpression of aquaporin-4 in human supratentorial meningiomas with peritumoral brain edema and correlation of VEGF with edema formation.
Peritumoral brain edema is a common complication of meningiomas. It is believed that vascular endothelial growth factor (VEGF), as an angiogenic factor, plays a vital role in edema formation. Aquaporin-4 (AQP4) is a small integral membrane protein that regulates water in the normal brain. However, the expression of AQP4 and its relationship to VEGF in edematous meningiomas are not well kno...
