背景信息

Interleukin-18 receptor accessory protein (IL18RAP), also known as IL-18Rβ or IL-1R7. is a critical component of the interleukin-18 (IL-18) receptor complex. IL-18 is a pro-inflammatory cytokine belonging to the IL-1 superfamily, primarily involved in regulating innate and adaptive immune responses. The functional IL-18 receptor consists of two subunits: IL-18Rα (IL-1R5) and IL18RAP. While IL-18Rα binds IL-18 with low affinity, IL18RAP serves as a co-receptor required for high-affinity ligand binding and downstream signal transduction. This interaction triggers the recruitment of adaptor proteins like MyD88. activating NF-κB and MAPK pathways, ultimately driving the production of inflammatory mediators such as IFN-γ.

Recombinant IL18RAP proteins are engineered versions of this receptor subunit, typically produced in mammalian or insect expression systems to ensure proper post-translational modifications. These proteins retain the extracellular domain responsible for IL-18 binding and receptor complex formation, making them valuable tools for studying IL-18 signaling mechanisms. Researchers utilize recombinant IL18RAP to investigate autoimmune diseases, chronic inflammation, and cancer, where dysregulated IL-18 signaling has been implicated. For instance, elevated IL-18 levels correlate with conditions like inflammatory bowel disease, rheumatoid arthritis, and certain malignancies.

In therapeutic development, recombinant IL18RAP serves as a decoy receptor or competitive inhibitor to neutralize excessive IL-18 activity. Its structural characterization also aids in designing small-molecule inhibitors targeting the IL-18 pathway. Additionally, it finds application in diagnostic assays and vaccine research, given IL-18's role in enhancing Th1-mediated immune responses. Recent studies explore IL18RAP polymorphisms linked to altered immune responses, further highlighting its clinical relevance. Purified through affinity chromatography and validated via techniques like SDS-PAGE and mass spectrometry, recombinant IL18RAP remains essential for both basic research and translational applications in immunology and precision medicine.
