IL-1R2 is structurally similar to IL-1R1 but lacks the Toll/IL-1 receptor (TIR) domain in its cytoplasmic region, which is essential for signal transduction . As a result, IL-1R2 cannot transduce signals and instead functions as a decoy receptor. By binding to IL1A, IL1B, and IL1Ra, IL-1R2 prevents these cytokines from interacting with their signaling receptors, thereby inhibiting their biological activities .
The primary role of IL-1R2 is to modulate the immune response by neutralizing the effects of IL1A and IL1B. This decoy receptor mechanism is crucial in regulating inflammation and preventing excessive immune responses . IL-1R2 is expressed in various tissues, including the immune system, and its expression can be induced by interleukin-4 (IL4), which further enhances its anti-inflammatory properties .
Recombinant human IL-1R2 is produced using recombinant DNA technology, which involves inserting the IL1R2 gene into a suitable expression system, such as bacteria or mammalian cells. This allows for the large-scale production of IL-1R2 protein, which can be used for research and therapeutic purposes .
Recombinant IL-1R2 has several applications in biomedical research and clinical settings:
