内容記述 | Subarachnoid hemorrhage (SAH) is a devastating disease. Cerebral vasospasm is still an important cause of post-SAH poor outcomes, but its mechanisms remain unveiled. Activation of epidermal growth factor receptor (EGFR) is suggested to cause vasoconstriction in vitro, but no report has demonstrated the involvement of EGFR in vasospasm development after SAHin vivo. Cross-talk of EGFR and vascular endothelial growth factor (VEGF) receptor, which may affect post-SAH vasospasm, was also reported in cancer cells, but has not been demonstrated in post-SAH vasospasm. The aim of this study was to investigate whether EGFR as well as EGFR-VEGF receptor crosstalk engage in the development of cerebral vasospasm in a mouse SAH model. C57BL6 mice underwent endovascular perforation SAH or sham modeling. At 30 min post-modeling, mice were randomly administrated vehicle or 2 doses of selective EGFR inhibitors intracerebroventricularly. A higher dose of the inhibitor significantly prevented post-SAH neurological impairments at 72 h and vasospasm at 24 h associated with suppression of post-SAH activation of EGFR and extracellular signal-regulated kinase (ERK) 1/2 in the cerebral artery wall, especially in the smooth muscle cell layers. Anti-EGFR neutralizing antibody also showed similar effects. However, neither expression levels of VEGF nor activation levels of a major receptor of VEGF, VEGF receptor-2, were affected by SAH and two kinds of EGFR inactivation. Thus, this study first showed that EGFR-ERK1/2 pathways may be involved in post-SAH vasospasm development, and that EGFR-VEGF receptor cross-talk may not play a significant role in the development of vasospasm in mice. | |||||||||||
