Human Interleukin 5 Receptor alpha (IL5RA) CLIA Kit

Background

Interleukin-5 receptor subunit alpha (IL5RA) is a protein critical for mediating immune responses involving eosinophils. Encoded by the IL5RA gene, this receptor forms a part of the IL-5 receptor complex, which is primarily responsible for binding interleukin-5 (IL-5), a cytokine crucial in regulating the growth, differentiation, and activation of eosinophils and basophils. Eosinophils, in particular, are involved in immune responses against parasitic infections and play a role in allergic inflammation and diseases such as asthma and eosinophilic esophagitis. IL-5, along with its receptor IL5RA, is also implicated in the development and maintenance of T-helper 2 (Th2)-mediated immune responses, which play a role in allergic diseases. By engaging IL5RA on eosinophils and other cells, IL-5 signaling promotes survival, activation, and accumulation of these cells at inflammatory sites. Due to its central role in driving eosinophil-mediated inflammation, IL5RA is a target for therapeutic interventions, especially in asthma, chronic rhinosinusitis with nasal polyps, and hypereosinophilic syndrome.
