线粒体和内质网(ER)网络是维持细胞内稳态和决定细胞命运的基础。最近的结构和功能研究揭示了这些网络的相互作用。ER和线粒体之间的这些紧密接触区域称为MAM(线粒体相关膜),支持两个细胞器之间的通信,包括生物能量学和细胞存活。在这些接触点的大分子复合物的存在也被揭示。在这篇文章中,我们将回顾:i)ER和线粒体的结构和动力学,ii)ER线粒体Ca 2+转运的基本原理,(iii)这种串扰的生理/病理作用。
Mitochondrial and endoplasmic reticulum (ER) networks are fundamental for the maintenance of cellular homeostasis and for determination of cell fate under stress conditions. Recent structural and functional studies revealed the interaction of these networks. These zones of close contact between ER and mitochondria called MAM (mitochondria associated membranes) support communication between the two organelles including bioenergetics and cell survival. The existence of macromolecular complexes in these contact sites has also been revealed. In this contribution, we will review: i) the ER and mitochondria structure and their dynamics, ii) the basic principles of ER mitochondrial Ca2+ transport, (iii) the physiological/pathological role of this crosstalk.
