Mitochondrial components secretion in extracellular vesicles promotes alveolar epithelial mitochondrial quality control.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The quality control network in type 2 alveolar epithelial cells (AEC2s) is essential to respond to intrinsic and extrinsic challenges. However, the mechanisms that regulate AEC2 mitochondrial homeostasis remain unclear understood. Here, we report a role of G protein-coupled receptor class C group 5 member A (GPRC5A) in mitochondrial quality control in AEC2s through promoting mitochondrial secretion in extracellular vesicles (EVs). Utilizing mice models, we demonstrate that the disruption of GPRC5A specifically in AEC2s aggravates lung injuries. We further observe that GPRC5A deficiency in AEC2s reduces secretion of mitochondrial components in small-EVs and disrupts mitochondrial functions both in vitro and in vivo. Mechanistically, we determine that the GPRC5A-MIRO2 pathway facilitates the transfer of mitochondrial fragments into late endosomes. Collectively, our findings provide evidence of the shedding of mitochondrial components dependent on GPRC5A as a pathway of mitochondrial quality control in AEC2s, which is crucial in the maintenance of epithelial physiological activities and lung tissue homeostasis.
