背景信息

Interleukin-22 receptor (IL-22R) is a heterodimeric protein complex composed of two subunits: IL-22R1 (IL-22RA1) and IL-10R2 (IL-10RB). It belongs to the class II cytokine receptor family and serves as the primary signaling receptor for interleukin-22 (IL-22), a member of the IL-10 cytokine family. IL-22 is predominantly produced by immune cells, including T helper 17 (Th17) cells, innate lymphoid cells (ILCs), and γδ T cells, and plays a critical role in modulating tissue responses at barrier surfaces, such as the skin, lungs, and gastrointestinal tract. The binding of IL-22 to IL-22R activates downstream signaling pathways, primarily the JAK-STAT (Janus kinase-signal transducer and activator of transcription) cascade, leading to STAT3 phosphorylation and the regulation of genes involved in cell survival, proliferation, and antimicrobial defense.

Recombinant IL-22R proteins are engineered versions of the receptor or its subunits, often produced in mammalian or insect cell systems to ensure proper post-translational modifications. These proteins are widely used in research to study IL-22 signaling mechanisms, receptor-ligand interactions, and the pathophysiological roles of IL-22 in diseases such as psoriasis, inflammatory bowel disease (IBD), and cancer. For example, soluble IL-22R1 ectodomain can act as a decoy receptor to neutralize IL-22 activity, providing insights into therapeutic strategies for IL-22-driven pathologies. Conversely, recombinant IL-22R complexes may also be employed to enhance IL-22 signaling in models of tissue repair or infection.

The development of IL-22R-targeted therapies remains an active area of investigation, particularly for conditions involving dysregulated epithelial immunity. However, the duality of IL-22’s roles—both protective and pro-inflammatory—requires careful modulation of its receptor interactions. Recombinant IL-22R proteins thus serve as essential tools for dissecting these complexities and advancing translational applications.
