Vagal neuroimmune circuits in inflammation and immunity.

Vagal neuroimmune circuits are key mediators of immune responses, with vagal sensory neurons detecting inflammatory cues and modulating immunity in health and disease.

• Why it matters: Understanding how the vagus nerve communicates with the immune system is crucial for developing targeted therapies for chronic inflammatory and autoimmune disorders, addressing a significant clinical need.
• What they did: The review examines the structural and functional organization of vagal neuroimmune pathways, focusing on how vagal sensory neurons encode inflammatory signals and influence immune responses, alongside advances in bioelectronic medicine.
• The result: Clarifying the cellular and physiological specifics of vagal neuroimmune circuits will enable the development of precise neuromodulation strategies, potentially improving treatments for inflammatory conditions.
