In this chapter, we mainly focus on the functions of TRPC channels in brain development, including neural progenitor proliferation, neurogenesis, neuron survival, axon guidance, dendritic morphology, synaptogenesis, and neural plasticity. We also notice emerging advances in understanding the functions of TRPC channels in periphery, especially their functions in sensation and nociception in dorsal root ganglion (DRG). Because TRPC channels are expressed in all major types of glial cells, which account for at least half of total cells in the brain, TRPC channels may act as modulators for glial functions as well. The future challenges for studying these channels could be (1) the detailed protein structures of these channels, (2) their cell type-specific functions, (3) requirement for their specific blockers or activators, and (4) change in the channel conformation in the brain.
在本章中,我们主要关注瞬时受体电位经典型(TRPC)通道在脑发育中的功能,包括神经祖细胞增殖、神经发生、神经元存活、轴突导向、树突形态、突触形成和神经可塑性。我们也注意到在理解TRPC通道在外周的功能方面的新进展,尤其是它们在背根神经节(DRG)的感觉和伤害感受中的功能。由于TRPC通道在所有主要类型的神经胶质细胞中均有表达,而神经胶质细胞至少占脑内细胞总数的一半,因此TRPC通道也可能作为神经胶质细胞功能的调节因子。研究这些通道未来面临的挑战可能包括:(1)这些通道的详细蛋白质结构;(2)它们的细胞类型特异性功能;(3)对其特异性阻断剂或激活剂的需求;(4)脑内通道构象的变化。
