免疫反应是由多种免疫细胞协调的。每个细胞的功能由来自各种免疫受体的集体信号决定,其表达和活性取决于细胞的发育阶段及其环境背景。最近的研究强调了机械力在几种免疫受体-配体对上的存在以及力在调节它们的相互作用和功能中的重要作用。在这个角度来看,我们使用的T细胞抗原受体作为一个例子,以审查目前的理解免疫受体的机械传感性能。我们讨论了免疫受体可能遇到的力的类型和力对配体结合、构象变化和免疫受体触发的影响,以及力对下游信号转导、细胞命运决定和免疫细胞效应器功能的影响。
The immune response is orchestrated by a variety of immune cells. The function of each cell is determined by the collective signals from various immunoreceptors, whose expression and activity depend on the developmental stages of the cell and its environmental context. Recent studies have highlighted the presence of mechanical force on several immunoreceptor–ligand pairs and the important role of force in regulating their interaction and function. In this Perspective, we use the T cell antigen receptor as an example with which to review the current understanding of the mechanosensing properties of immunoreceptors. We discuss the types of forces that immunoreceptors may encounter and the effects of force on ligand bonding, conformational change and the triggering of immunoreceptors, as well as the effects of force on the downstream signal transduction, cell-fate decisions and effector function of immune cells.
