摘要

细胞信号传导是一个基本的细胞过程,它使细胞能够感知和响应周围环境的信息。在分子水平上,信号传导主要是由跨膜蛋白受体进行的,它可以启动复杂的下游信号转导级联反应来改变细胞行为。在人体内,不同的细胞可以暴露在各种各样的环境条件下,细胞表达不同种类的受体,能够感知和整合不同的信号。此外,不同的受体和信号通路可以相互串扰,以校准细胞反应。串扰在信号通路的不同层次上通过多种机制发生。在这篇综述中,我们讨论了细胞如何感知和整合不同的化学、机械和空间信号,以及通路之间的串扰机制。为了说明这些概念,我们使用了一些经过充分研究的信号通路,包括受体酪氨酸激酶和整合素受体。最后,我们讨论了失调的细胞传感对驱动疾病(如癌症)的影响。本文分类为:癌症>分子与细胞生理>代谢疾病>分子与细胞生理。

How cells sense and integrate information from different sources.

Cell signaling is a fundamental cellular process that enables cells to sense and respond to information in their surroundings. At the molecular level, signaling is primarily carried out by transmembrane protein receptors that can initiate complex downstream signal transduction cascades to alter cellular behavior. In the human body, different cells can be exposed to a wide variety of environmental conditions, and cells express diverse classes of receptors capable of sensing and integrating different signals. Furthermore, different receptors and signaling pathways can crosstalk with each other to calibrate the cellular response. Crosstalk occurs through multiple mechanisms at different levels of signaling pathways. In this review, we discuss how cells sense and integrate different chemical, mechanical, and spatial signals as well as the mechanisms of crosstalk between pathways. To illustrate these concepts, we use a few well-studied signaling pathways, including receptor tyrosine kinases and integrin receptors. Finally, we discuss the implications of dysregulated cellular sensing on driving diseases such as cancer. This article is categorized under: Cancer > Molecular and Cellular Physiology Metabolic Diseases > Molecular and Cellular Physiology.
