🚨PREPRINT ALERT How different are males and females? In physiology we mostly treat that as a fixed property of a species, something to control for. In mice, we found it is not fixed at all. It depends on what the animal ate while growing up.

Juvenile protein restriction compresses sexual dimorphism in mice
Sexual dimorphism is canonically understood as a fixed adult trait, scaled by gonadal hormones at puberty, but whether its magnitude is shaped earlier in life by juvenile nutrition during the post-wea...

Encrypted peptides are hidden within larger proteins, but their roles in #immunity remain obscure. This Essay explores how proteolytically released peptides are discovered and how their mechanism of action helps to shape immunity & physiology @plosbiology.org 🧪 plos.io/4ybOQfh
Conceptual model of encrypted immunity. Proteins expressed in immune and non-immune tissues can be processed by proteases, the proteasome, or autophagy-associated pathways to release encrypted peptides. Depending on the tissue context and biological state, these peptides may exert direct antimicrobial effects, modulate inflammatory signaling, alter chemotaxis, or participate in broader physiological processes. Examples informing this model include human proteome-derived encrypted peptides, thrombin-derived C-terminal peptides, and proteasome-derived defense peptides. Infection, injury, or inflammatory cues may in turn reshape peptide generation, creating a dynamic feedback system between proteolysis and host defense. Created in BioRender.
