Physiology and immunology of the adrenergic anti-inflammatory pathway.

Abstract

The adrenergic anti-inflammatory pathway represents a critical intersection between the nervous and immune systems, modulating the body's response to inflammation through the action of catecholamines on adrenergic receptors. This review explored the physiology underlying this pathway, focusing on the mechanisms by which the sympathetic nervous system influences immune function. We delved into the roles of specific adrenergic receptors, primarily the beta-adrenergic receptors, in mediating anti-inflammatory effects, highlighting the involved molecular signaling pathways. Additionally, we examined the immunological implications of adrenergic modulation, discussing how these pathways contributed to the resolution of inflammation and the potential for dysregulation in various disease states. Emerging evidence on the therapeutic potential of targeting the adrenergic anti-inflammatory pathway in conditions such as sepsis, autoimmune diseases, and chronic inflammatory disorders was also reviewed. By integrating current knowledge on the physiology and immunology of this pathway, this review aimed to provide a comprehensive understanding of its role in health and disease, offering insights into future research directions and clinical applications.
