细胞内钙([Ca~(2+)]_i)信号调节大多数细胞的生理功能。在胰腺、唾液腺和泪腺(LG)等分泌器官中,腺泡细胞内[Ca~(2+)]i升高触发液体分泌,在维持整个生命过程中的功能健康方面起着至关重要的作用。了解分泌器官的分泌机制是很重要的,但缺乏可用于活体动物的分析系统限制了对分泌精确机制的深入了解的研究范围。我们建立了一个针对特定细胞类型的分泌器官的活体成像系统,以监测[Ca2+]i的变化,使用表达黄色Cameleon 3.60的小鼠,黄色Cameleon 3.60是一种遗传编码的钙指示剂。胆碱能刺激后,可监测特定细胞类型分泌器官内[Ca~(2+)]i的升高。我们发现,在病理条件下,节后去神经可引起Lg[Ca~(2+)]i对胆碱能刺激的反应显著减弱。在分泌器官中进行活体钙离子成像将有助于我们理解分泌性疾病动物模型的细胞机制。
Intracellular calcium ([Ca2+]i) signaling regulates physiological functions in most cells. In secretory organs, such as the pancreas, salivary gland, and lacrimal gland (LG), [Ca2+]i elevation in acinar cells triggers fluid secretion, which plays vital roles in the maintenance of functional health across the life-course. It is important to understand the secretory mechanism of secretory organs, but lack of analytic systems available for living animals limits the scope of research to gain deeper insights into the precise mechanism of secretion. We established an intravital imaging system for specific cell types of secretory organs to monitor the [Ca2+]i changes using mouse line expressing Yellow Cameleon 3.60, a genetically encoded Ca2+ indicator. Elevation of [Ca2+]i in specific cell types of secretory organs could be monitored after cholinergic stimulation ex vivo and intravitally. We found that a marked attenuation of LG [Ca2+]i response to cholinergic stimulation was induced under pathological conditions by postganglionic denervation. Intravital Ca2+ imaging in secretory organs will broaden our understanding of the cellular mechanisms in animal models of secretory diseases.
