Despite considerable advances in the research and treatment, the precise relationship between inflammation and cardiovascular (CV) disease remains incompletely understood. Therefore, understanding the immunoinflammatory processes underlying the initiation, progression, and exacerbation of many cardiovascular diseases is of prime importance. The innate immune system has an ancient origin and is well conserved across species. Its activation occurs in response to pathogens or tissue injury. Recent studies suggest that altered ionic balance, and production of noxious gaseous mediators link to immune and inflammatory responses with altered ion channel expression and function. Among plausible candidates for this are transient receptor potential (TRP) channels that function as polymodal sensors and scaffolding proteins involved in many physiological and pathological processes. In this review, we will first focus on the relevance of TRP channel to both exogenous and endogenous factors related to innate immune response and transcription factors related to sustained inflammatory status. The emerging role of inflammasome to regulate innate immunity and its possible connection to TRP channels will also be discussed. Secondly, we will discuss about the linkage of TRP channels to inflammatory CV diseases, from a viewpoint of inflammation in a general sense which is not restricted to the innate immunity. These knowledge may serve to provide new insights into the pathogenesis of various inflammatory CV diseases and their novel therapeutic strategies.
尽管在研究和治疗方面取得了显著进展,但炎症与心血管(CV)疾病之间的确切关系仍未完全明确。因此,了解许多心血管疾病发生、发展和加重背后的免疫炎症过程至关重要。固有免疫系统起源古老,在物种间高度保守。其激活是对病原体或组织损伤的反应。最近的研究表明,离子平衡改变以及有害气体介质的产生与免疫和炎症反应相关,且与离子通道表达和功能改变有关。其中合理的候选者包括瞬时受体电位(TRP)通道,它作为多模式传感器发挥作用,以及参与许多生理和病理过程的支架蛋白。在这篇综述中,我们将首先关注TRP通道与固有免疫反应相关的外源性和内源性因素以及与持续炎症状态相关的转录因子的相关性。还将讨论炎性小体在调节固有免疫中的新兴作用及其与TRP通道的可能联系。其次,我们将从广义的炎症角度(不限于固有免疫)讨论TRP通道与炎性心血管疾病的联系。这些知识可能有助于为各种炎性心血管疾病的发病机制及其新的治疗策略提供新的见解。
