Vagal Heart–Brain Dysregulation in PTSD Mice
2026-09-21
A 2026 European Journal of Pharmacology study identifies a causal heart–insula pathway in which sympathetically driven cardiac activation is transmitted through the vagus nerve to produce insular cortex hyperactivity and PTSD-like behavior. Its combination of stress modeling, chronic isoproterenol exposure, vagotomy, electrophysiology, and propranolol intervention provides a useful framework for mechanistic heart–brain axis research.

Viperin Targets nsp8 to Block Coronavirus Replication
2026-09-20
A 2026 study identifies a previously unrecognized antiviral mechanism in which viperin binds coronavirus nsp8, disrupts replication-transcription complex assembly, and reduces RNA-dependent RNA polymerase activity. Using porcine deltacoronavirus as a model, the work separates this protein-interaction mechanism from ddhCTP-mediated chain termination and highlights nsp8 as a potentially conserved target for broad-spectrum antiviral drug development.
