Clostridium perfringens Delta toxin is identified as a virulence factor that drives intestinal necrosis and acute cerebral injury in necrotizing enterocolitis (NEC). A genome-wide CRISPR screen reveals CD9 as the host receptor, and anti-Delta toxin antibody protects against disease progression.
Key points
Delta toxin preferentially targets macrophages, activating inflammasome signalling and pyroptosis, leading to blood-brain barrier disruption.
Systemic and myeloid-specific Cd9 knockout mice are protected from toxin-induced lethality, blood-brain barrier dysfunction and multiorgan injury.

Brain-first body-first model applied to individual Parkinson’s patients
Brain-first body-first model applied to individual Parkinson’s patients shows probable RBD classifies 85% of early cases. Other clinical and imaging features performed poorly as individual classifiers.
Key points
Probable RBD status correctly classified 85% of patients.
Other clinical and imaging features performed poorly as individual-level classifiers.

ML & AI predictive modeling in precision medicine – 31 papers
Editorial summarizes 31 papers that argue precision medicine needs structural domain knowledge before model training. It outlines three transitions: anchoring algorithms in biological laws, creating human-centered clinical interfaces, and scaling equitable population-level interventions.
Key points
Three necessary transitions: mechanistic interpretability, collaborative interfaces, equitable scaling.
Smartphone-based graph convolutional networks assess Parkinsonian gait asymmetry at home.
