长期以来人们已经认识到,内质网(ER)和线粒体(对于正常细胞功能和存活重要的细胞器)也在各种肺部疾病(包括哮喘、纤维化和感染)的发病机制中起关键作用。在这些细胞器内调节的过程中的改变,包括但不限于ER中的蛋白质折叠和线粒体中的氧化磷酸化,在疾病发病机制中是重要的。近年来,细胞器结构决定功能也变得越来越明显。现在清楚的是,细胞器必须保持精确的组织和定位,才能正常发挥功能。新的显微镜功能使科学界能够通过3D成像揭示这些细胞器的结构及其相互作用是调节功能的主要组成部分,因此对疾病状态产生影响。在这篇综述中,我们将研究如何通过3D成像技术可以让知识的ER和线粒体的功能,以及它们可能在肺上皮细胞在肺部疾病的进展中发挥的作用的进步。
It has long been appreciated that the endoplasmic reticulum (ER) and mitochondria, organelles important for regular cell function and survival, also play key roles in pathogenesis of various lung diseases, including asthma, fibrosis, and infections. Alterations in processes regulated within these organelles, including but not limited to protein folding in the ER and oxidative phosphorylation in the mitochondria, are important in disease pathogenesis. In recent years it has also become increasingly apparent that organelle structure dictates function. It is now clear that organelles must maintain precise organization and localization for proper function. Newer microscopy capabilities have allowed the scientific community to reveal, via 3D imaging, that the structure of these organelles and their interactions with each other are a main component of regulating function and, therefore, effects on the disease state. In this review, we will examine how 3D imaging through techniques could allow advancements in knowledge of how the ER and mitochondria function and the roles they may play in lung epithelia in progression of lung disease.
