英文摘要
In B lymphocyte cell lines (A20 and DT 40), it was demonstrated that mitochondrial Na/Ca exchanger (NCLX) is associated with mitochondrial Ca extrusion, modulation of endoplasmic reticulum Ca content, endoplasmic reticulum Ca release upon BCR-stimulation, store-operated Ca entry and chemotaxis. In cardiomyocyte cell line (HL-1), it was also demonstrated NCLX extrudes mitochondrial Ca and modulates sarcoplasmic reticulum Ca content. Additionally, it was found that NCLX modulates spontaneous beating frequency. These results were well reproduced by mathematical models of B lymphocyte, HL-1 cell and sinoatrial node cell. Taken together, it was suggested that NCLX act as a Ca provider from mitochondria to sarco- and endo-plasmic reticulum.
