Ion channels play a crucial role in various aspects of cardiac function, such as regulating rhythm and contractility. As a result, they serve as key targets for therapeutic interventions in cardiovascular diseases. Cell function is substantially influenced by the concentration of free cytosolic calcium (Ca 2+ ) and the voltage across the plasma membrane. These characteristics are known to be regulated by Ca 2+ -permeable nonselective cationic channels, although our knowledge of these channels is still inadequate. The transient receptor potential (TRP) superfamily comprises of many nonselective cation channels with diverse Ca 2+ permeability. Canonical or classical TRP (TRPC) channels are a subgroup of the TRP superfamily that are expressed ubiquitously in mammalian cells. TRPC channels are multidimensional signaling protein complexes that play essential roles in a variety of physiological and pathological processes in humans, including cancer, neurological disorders, cardiovascular diseases, and others. The objective of this article was to focus on the role that TRPC channels play in the cardiovascular system. The role of TRPC channels will be deeply discussed in cardiovascular pathology. Together, a critical element in developing novel treatments that target TRPC channels is comprehending the molecular mechanisms and regulatory pathways of TRPC channels in related cardiovascular diseases and conditions.
离子通道在心脏功能的各个方面发挥着关键作用,例如调节节律和收缩性。因此,它们成为心血管疾病治疗干预的关键靶点。细胞功能受到游离胞质钙(Ca2+)浓度和质膜跨膜电压的显著影响。已知这些特性受Ca2+ 通透的非选择性阳离子通道调控,尽管我们对这些通道的了解仍然不足。瞬时受体电位(TRP)超家族由许多具有不同Ca2+ 通透性的非选择性阳离子通道组成。典型或经典的TRP(TRPC)通道是TRP超家族的一个亚组,在哺乳动物细胞中普遍表达。TRPC通道是多维信号蛋白复合物,在人类多种生理和病理过程中发挥重要作用,包括癌症、神经疾病、心血管疾病等。本文的目的是聚焦TRPC通道在心血管系统中的作用。TRPC通道的作用将在心血管病理学中深入讨论。总之,开发靶向TRPC通道的新型治疗方法的一个关键要素是理解TRPC通道在相关心血管疾病和病症中的分子机制和调控途径。
