项目摘要
In the urine storage phase, mechanical stretch stimulates bladder afferents. These urinary bladder afferent sensory nerves consist of small diameter Aδ- and C-fibers running in the hypogastic and pelvic nerves. Neuroanatomical studies have revealed a complex neuronal network within the bladder wall. The exact mechanisms that underline mechano-sensory transduction in bladder afferent terminals remain ambiguous ; however, a wide range of ion channels (e.g. TTX-resistant Na+ channels, Kv channels and hyperpolarization-activated cyclic nucleotidegated cation channels, degenerin/epithelial Na+ channel), and receptors (e.g. TRPV1, TRPM8, TRPA1, P2X2/3, etc.) have been identified at bladder afferent terminals and have implicated in the generation and modulation of afferent signals, which are elcited by a wide range of bladder stimulations including physiological bladder filling, noxious distension, cold, chemical irritation and inflammation. The mammalian transient receptor potential (TRP) family consists of 28 channels that can be subdivided into six different classes : TRPV (vanilloid), TRPC (canonical), TRPM (Melastatin), TRPP (Polycystin), TRPML (Mucolipin), and TRPA (Ankyrin). TRP channels are activated by a diversity of physical (voltage, heat, cold, mechanical stress) or chemical (pH, osmolality) stimuli and by binding of specific ligands, enabling them to act as multifunctional sensors at the cellular level. TRPV1, TRPV2, TRPV4, TRPM8, and TRPA1 have been described in different parts of the urogenital tract. Although only TRPV1 among TRPs has been extensively studied so far, more evidence is slowly accumulating about the role of other TRP channels, ion channels, and receptors in the pathophysiology of the urogenital tract, and may provide a new strategy for the treatment of bladder dysfunction.
在尿液存储阶段,机械拉伸刺激膀胱传入。这些泌尿膀胱传入的感觉神经由降低和骨盆神经中的小直径Aδ和C纤维组成。神经解剖学研究揭示了膀胱壁中一个复杂的神经元网络。强调膀胱传入终端中的机理 - 感官转导的确切机制仍然模棱两可;但是,多种离子通道(例如TTX耐药Na+通道,KV通道和超极化激活的环状核毒性阳离子通道,degenerin/Epithelial Na+通道),以及受体(例如,TRPV1,TRPM8,TRPM8,P2X2/3等),该受体已确认传入信号的产生和调节,这些信号受到广泛的膀胱刺激,包括物理膀胱填充,有害的延伸,冷,化学刺激和炎症。哺乳动物瞬态受体电位(TRP)家族由28个通道组成,可以细分为六个不同的类别:TRPV(Vanilloid),TRPC(canonical),TRPM(Melastatin),TRPP(Polycystin),TRPP(Polycystin),TRPML(Mucolipin)和TRPA(Ankyrin)。 TRP通道通过多种物理(电压,热,冷,机械应力)或化学(pH,渗透压)刺激激活,并通过特定配体的结合,使它们能够在细胞水平上充当多功能传感器。 TRPV1,TRPV2,TRPV4,TRPM8和TRPA1已在泌尿生殖道的不同部分中进行了描述。尽管到目前为止,在TRP中仅进行了大量研究,但更多的证据正在慢慢积累有关其他TRP通道,离子通道和受体在泌尿生殖道病理生理学中的作用,并可能为膀胱功能障碍的治疗提供新的策略。
