''Effect of stroke on arginase expression and localization in the rat brain''

2013

Quirie, Aurore | Demougeot, C. Eline | Bertrand, Nathalie | Mossiat, Claude | Garnier, Philippe | Marie, Christine | Prigent-Tessier, Anne; International audience; ''Because arginase and nitric oxide (NO) synthases (NOS) compete to degrade l-arginine, arginase plays a crucial role in the modulation of NO production. Moreover, the arginase 1 isoform is a marker of M2 phenotype macrophages that play a key role in tissue remodeling and resolution of inflammation. While NO has been extensively investigated in ischemic stroke, the effect of stroke on the arginase pathway is unknown. The present study focuses on arginase expression/activity and localization before and after (1, 8, 15 and 30days) …

The Role of Erythropoietin in Neuroprotection: Therapeutic Perspectives

2007

Nervous system diseases are very complex conditions comprising a large variety of local and systemic responses. Several therapeutic agents interfering with all or in part the biochemical steps that ultimately cause neuronal death have been demonstrated to be neuroprotective in preclinical models. However, all the agents so far investigated have inexorably failed in the phase III trials carried out. A large body of evidence suggests that the hormone erythropoietin (EPO), besides its well-known hematopoietic action, exerts beneficial effects in the central nervous system. EPO's effect has been assessed in several experimental models of brain and spinal cord injury thus becoming a serious cand…

ERYTHROPOIETIN FOR THE TREATMENT OF SUBARACHNOID HEMORRAGE: A FEASIBLE INGREDIENT FOR A SUCCESS MEDICAL RECIPE

2015

Subarachnoid hemorrhage (SAH) following aneurysm bleeding accounts for 6% to 8% of all cerebrovascular accidents. Although an aneurysm can be effectively managed by surgery or endovascular therapy, delayed cerebral ischemia is diagnosed in a high percentage of patients resulting in significant morbidity and mortality. Cerebral vasospasm occurs in more than half of all patients after aneurysm rupture and is recognized as the leading cause of delayed cerebral ischemia after SAH. Hemodynamic strategies and endovascular procedures may be considered for the treatment of cerebral vasospasm. In recent years, the mechanisms contributing to the development of vasospasm, abnormal reactivity of cerebr…
