Mitochondrial-derived microproteins in lung disease: insights and implications.
Editor's note
This review, co-authored by figures central to the MDP field, maps what is and isn't known about mitochondrial-derived peptides, MOTS-c and humanin foremost, in lung homeostasis and disease. Its value is honest gap-identification: most MDP work has centred on heart, muscle, brain, and age-related disease, leaving pulmonary roles underexplored. There are no new data; the piece is a research agenda rather than evidence of benefit. For MOTS-c specifically it signals an emerging, still-thin area. Publishable as landscape context that helps readers calibrate how early the MOTS-c-in-lung story is, while making clear no clinical claims follow from it.
Plain-language abstract
Mitochondrial-derived peptides (MDPs) are tiny proteins coded within mitochondrial DNA that act as signalling molecules. The best-studied are MOTS-c and humanin. This review points out that most research on these peptides has focused on tissues with lots of mitochondria, like the heart, muscle, and brain, and on diseases of ageing such as Alzheimer's and cardiovascular disease. Far less is known about what MDPs do in the lungs. The authors highlight this gap and argue that MDPs deserve study in lung conditions like acute lung injury, chronic obstructive pulmonary disease, asthma, and pulmonary fibrosis. Because it is a review flagging open questions rather than a new experiment, it does not provide evidence that MOTS-c helps any lung condition; it simply makes the case that the area is worth investigating. For readers, the useful message is that MOTS-c's role in lung disease is an early, largely unexplored research frontier.
