背景信息

**Background of IL1RN Recombinant Protein**

The interleukin-1 receptor antagonist (IL1RN), also known as IL-1Ra, is a naturally occurring cytokine inhibitor that modulates the inflammatory response by blocking the activity of interleukin-1 (IL-1), a key mediator of inflammation. IL-1 exists in two forms, IL-1α and IL-1β, both signaling through the IL-1 receptor (IL-1R1) to promote inflammation, fever, and tissue damage in conditions like autoimmune diseases, sepsis, and arthritis. IL1RN acts as a competitive antagonist by binding to IL-1R1 without activating downstream signaling, thereby suppressing excessive IL-1-driven inflammation.

The recombinant form of IL1RN is produced using genetic engineering techniques, often in bacterial (e.g., *E. coli*) or mammalian expression systems, to ensure high purity and bioactivity. Recombinant IL1RN mirrors the structure and function of the native protein, enabling its therapeutic use. Clinically, it has been studied and applied in diseases where IL-1 overactivity is pathological. For example, Anakinra, a synthetic version of IL1RN, is FDA-approved for rheumatoid arthritis and neonatal-onset multisystem inflammatory disease (NOMID).

Research into IL1RN also explores its role in other conditions, such as type 2 diabetes, cardiovascular diseases, and gout, where inflammation contributes to pathogenesis. Its recombinant production allows scalable, consistent manufacturing for both therapeutic and research applications, aiding in the study of IL-1 signaling pathways and inflammation mechanisms.

Overall, IL1RN recombinant protein represents a critical tool in understanding and managing IL-1-mediated disorders, highlighting the intersection of immunology, molecular biology, and clinical therapeutics.
