骨髓基质构成了骨髓-血液屏障,在全身性细菌感染的后遗症中维持免疫化学稳态并保护造血组织。在这些条件下,受循环细菌病原体影响的骨髓基质细胞将引发适应性应激反应机制,以维持屏障的完整性。本次交流的目的是证明(i)用表皮葡萄球菌体外挑战间充质基质细胞(即集落形成单位成纤维细胞(CFU-F))可以激活自噬途径以执行抗菌防御反应,以及(ii)由于细菌诱导的应激导致的同源平衡转变包括线粒体重塑和通过线粒体自噬隔离受损的细胞器。Drp 1和PINK 1-PARK 2依赖性机制在间充质基质细胞中异常线粒体的线粒体自噬周转中的意义进行了研究和讨论。
The bone marrow stroma constitutes the marrow-blood barrier, which sustains immunochemical homoeostasis and protection of the haematopoietic tissue in sequelae of systemic bacterial infections. Under these conditions, the bone marrow stromal cells affected by circulating bacterial pathogens shall elicit the adaptive stress-response mechanisms to maintain integrity of the barrier. The objective of this communication was to demonstrate (i) that in vitro challenge of mesenchymal stromal cells, i.e. colony-forming unit fibroblasts (CFU-F), with Staphylococcus epidermidis can activate the autophagy pathway to execute antibacterial defence response, and (ii) that homoeostatic shift because of the bacteria-induced stress includes the mitochondrial remodelling and sequestration of compromised organelles via mitophagy. Implication of Drp1 and PINK1–PARK2-dependent mechanisms in the mitophagy turnover of the aberrant mitochondria in mesenchymal stromal cells is investigated and discussed.
