Background

Interleukin-15 receptor α (IL15RA), also known as CD215 or IL-15Rα, is a member of the type I cytokine receptor family and is an important component of proinflammatory signaling for interleukin 15 (IL15). IL15 and IL15RA are present in the circulation and have been detected in a variety of tissues, where they affect physiological functions such as muscle contractility and overall metabolism. (PMID: 28602725) IL-15Rα signals in both cis and trans, where cis signaling means that IL-15 binds to its receptor on the same cell, and trans signaling means that IL-15 signals through extracellular IL-15Rα. IL15/IL15RA autocrine growth-stimulating loops are found in human T-cell lymphotropic virus 1 ( HTLV-1)-associated adult T-cell leukemia/lymphoma progression. (PMID: 36009415)
