New review: Intrapartum antibiotics have reduced early-onset neonatal group B strep disease, but late-onset disease persists. We explore GBS virulence, neonatal immunity, microbiome effects, and new paths for prevention, including vaccines and probiotics. link.springer.com/article/10.1...

Online now: Sensory neurons shape local macrophage identity via TGF-β signaling

Sensory neurons shape local macrophage identity via TGF-β signaling
Specialized macrophages are known to persist within tissue niches, but the molecular mechanisms guiding their sustained functional adaptation remain unclear. Kolter and Döring et al. show that local interactions between sensory nerves and macrophages activate TGF-β, which imprints and maintains nerve-associated macrophages that contribute to regeneration after tissue injury.
