## Abstract

The transient receptor potential vanilloid type 1 (TRPV1) channel, a member of the TRP ion channel family, plays a crucial role in both physiological and pathological processes. This review provides an overview of the structure, biological functions, and implications of TRPV1 in autoimmune diseases. The structural characteristics of TRPV1, including its transmembrane and intracellular domains, are examined to understand its activation and modulation. In addition to its well-known role as a thermosensor in nociceptive neurons, TRPV1 has been found to have functions in immune cells where it regulates lipid synthesis and inflammatory response. The investigation of TRPV1’s involvement in autoimmune conditions such as systemic lupus erythematosus, multiple sclerosis, and rheumatoid arthritis highlights its potential as a therapeutic target. The search for selective agonists and antagonists for TRPV1 drugs is also discussed. A comprehensive understanding of TRPV1’s structure, function, and role in autoimmune diseases lays the foundation for future studies and the development of innovative therapies targeting this channel.
