分泌是一个基本的细胞过程,涉及细胞内产物的调节释放。生理功能,如神经传递,激素和消化酶的释放,都是由细胞分泌控制的。参与分泌过程的异常有助于诸如糖尿病和其他激素紊乱等疾病的发生和进展。为了揭示控制这些疾病的机制,有必要了解激素、生长因子和神经递质是如何合成和加工的,以及它们的信号是如何通过靶细胞内的信号传导途径被识别、放大和传递的。在这里,我们讨论了基于数学模型的分泌的详细机制的各个方面。这些模型的范围从描述分泌囊泡运输的随机模型到研究激素分泌背后的细胞过程调控的确定性模型。在所有情况下,模型与实验结果密切相关,并提出了分泌机制的理论预测。
Secretion is a fundamental cellular process involving the regulated release of intracellular products from cells. Physiological functions such as neurotransmission, or the release of hormones and digestive enzymes, are all governed by cell secretion. Anomalies in the processes involved in secretion contribute to the development and progression of diseases such as diabetes and other hormonal disorders. To unravel the mechanisms that govern such diseases, it is essential to understand how hormones, growth factors and neurotransmitters are synthesized and processed, and how their signals are recognized, amplified and transmitted by intracellular signaling pathways in the target cells. Here, we discuss diverse aspects of the detailed mechanisms involved in secretion based on mathematical models. The models range from stochastic ones describing the trafficking of secretory vesicles to deterministic ones investigating the regulation of cellular processes that underlie hormonal secretion. In all cases, the models are closely related to experimental results and suggest theoretical predictions for the secretion mechanisms.
