The Role of PDZ in Cerebral Ischemia

Cerebral ischemia is a widespread disease and a leading cause of death and disability worldwide. Its complex origins and the mysterious mechanisms behind its development make it a formidable adversary in the field of medicine. PDZ proteins are part of the human proteome with multiple functions and have been identified as key mediators of cell signaling and synaptic transmission. Their interactions with PDZ-binding proteins underlie their role in the pathogenesis of a variety of diseases. In this paper, PDZ domains have been extensively studied, exploring their structural properties and functional roles in cells. This review highlights the importance of these domains in signal transduction pathways, which are essential for the normal function of the nervous system. It also highlights emerging evidence linking PDZ proteins to the regulation of angiogenesis in cerebrovascular diseases, a key process in the development of ischemic disease. In addition, we further discuss the potential of PDZ proteins in neuronal regeneration, an area that is expected to play a role in stroke development and subsequent rehabilitation. This review also discusses the link between PDZ proteins and excitatory synaptic transmission, further exploring the mechanisms involved in excitatory toxicity. By analyzing the complex relationship between PDZ proteins and their binding partner, this paper aims to reveal the molecular basis of cerebral ischemia. This suggests that a deeper understanding of these interactions could pave the way for innovative therapeutic interventions for stroke management. The review concludes by advocating continued research into PDZ proteins, recognizing their potential as building blocks for the development of new treatment and prevention strategies for stroke and related disorders.
