酸钙体是一种富含多磷酸盐、无机阳离子和有机阳离子的电子致密细胞器,可被质子泵酸化,具有多种通道、泵和转运体。它们存在于细菌和真核生物中,并在锥虫中进行了更详细的研究。对锥虫酸钙体生物发生的研究发现,它们与动物细胞中与溶酶体相关的细胞器具有相同的特性。除了它们在自噬、阳离子和磷储存、钙离子调节、pH稳态和发病机制中的作用外,最近的研究已经确定了这些细胞器在磷酸盐利用、钙离子(Ca2+)信号传导和生物能量学中的作用,这将是本文的主要主题。
Acidocalcisomes are electron-dense organelles rich in polyphosphate and inorganic and organic cations that are acidified by proton pumps, and possess several channels, pumps and transporters. They are present in bacteria and eukaryotes and have been studied in greater detail in trypanosomatids. Biogenesis studies of trypanosomatid acidocalcisomes found that they share properties with lysosome-related organelles of animal cells. In addition to their described roles in autophagy, cation and phosphorus storage, osmoregulation, pH homeostasis, and pathogenesis, recent studies have defined the role of these organelles in phosphate utilization, calcium ion (Ca2+) signaling, and bioenergetics, and will be the main subject of this review.
