The multiple roles of the NlpC_P60 peptidase family in mycobacteria – an underexplored target for antimicrobial drug discovery

FEBS Letters, Volume 599, Issue 9, Page 1203-1221, May 2025.
The NlpC_P60 superfamily of peptidases is recognised by its key role in bacterial cell wall homeostasis. Recently, studies have also described the involvement of NlpC_P60‐like enzymes in bacterial competitive mechanisms and pathogenesis across several lineages.

Antibodies and Inflammation: Fecal Biomarkers of Gut Health in Domestic Ruminants

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 4, Page 468-479, May 2025.
ABSTRACT Gastrointestinal infections present major challenges to ruminant livestock systems, and gut health is a key constraint on fitness, welfare, and productivity. Fecal biomarkers present opportunities to monitor animal health without using invasive methods, and with greater resolution compared to observational metrics.
