Abstract

The mechanisms governing neurological and functional recovery after ischemic stroke are incompletely understood. Recent advances in knowledge of intrinsic repair processes of the CNS have so far translated into minimal improvement in outcomes for stroke victims. Better understanding of the processes underlying neurological recovery after stroke is necessary for development of novel therapeutic approaches. Angiogenesis and neurogenesis have emerged as central mechanisms of post-stroke recovery and potential targets for therapeutics. Frameworks have been developed for conceptualizing cerebral angiogenesis and neurogenesis at the tissue and cellular levels. These models highlight that angiogenesis and neurogenesis are linked to each other and to functional recovery. However, knowledge of the molecular framework linking angiogenesis and neurogenesis after stroke is limited. Studies of potential therapeutics typically focus on one mediator or pathway with minimal discussion of its role within these multifaceted biochemical processes. In this article, we briefly review the current understanding of the coupled processes of angiogenesis and neurogenesis after stroke. We then identify the molecular mediators and signaling pathways found in pre-clinical studies to upregulate both processes after stroke and contextualizes them within the current framework. This report thus contributes to a more-unified understanding of the molecular mediators governing angiogenesis and neurogenesis after stroke, which we hope will help guide the development of novel therapeutic approaches for stroke survivors.

摘要

中风后神经和功能恢复的机制尚未完全阐明。目前,对中枢神经系统内在修复过程的认识的进展,仅使中风患者的预后略有改善。为了开发新的治疗方法,有必要更好地了解中风后神经恢复的过程。血管生成和神经发生已成为中风后恢复的核心机制和潜在治疗靶点。已经为在组织和细胞水平上概念化大脑血管生成和神经发生开发了框架。这些模型强调了血管生成和神经发生之间相互关联,并与功能恢复相关。然而,关于中风后血管生成和神经发生之间的分子框架的知识有限。潜在治疗方法的研究通常集中在一种介质或途径上,很少讨论其在这些多方面生化过程中的作用。在本文中,我们简要回顾了中风后血管生成和神经发生的偶联过程的当前认识。然后,我们确定了在中风后上调这两个过程的临床前研究中发现的分子介质和信号通路,并将它们置于当前框架内。因此,该报告有助于更统一地理解中风后血管生成和神经发生的分子介质,我们希望这将有助于指导中风幸存者的新治疗方法的开发。
