What this study reported

Reported that MOTS-c is an amphipathic cationic peptide with antibacterial activity against E. coli and methicillin-resistant S. aureus in culture, apparently through membrane targeting. Also reported that IFNγ, LPS and differentiation signals induced endogenous MOTS-c in monocytes and that MOTS-c translocated to the nucleus and shifted macrophage transcriptional programmes.

Limitations

Preprint that has not been peer reviewed; bacterial and cell culture assays only, with no animal or human infection data; replicate numbers are not reported.

Appraisal

Each dimension is recorded separately and never combined into a single score. A study can be well controlled and still tell you little about people.
