背景信息

Interleukin-22 (IL-22) is a member of the IL-10 cytokine family, primarily produced by immune cells such as T helper 17 (Th17) cells, group 3 innate lymphoid cells (ILC3s), and natural killer (NK) cells. It plays a dual role in modulating inflammatory responses and promoting tissue repair by targeting epithelial and stromal cells. Unlike many interleukins, IL-22 does not directly regulate immune cells but acts on non-hematopoietic cells expressing the IL-22 receptor complex (IL-22R1 and IL-10R2). This receptor is abundant at barrier surfaces, including the skin, gut, and lungs, making IL-22 critical for maintaining mucosal integrity, antimicrobial defense, and wound healing.

Recombinant IL-22 (rIL-22) is engineered through genetic cloning, often using mammalian or bacterial expression systems, to produce bioactive forms of the protein for research and therapeutic applications. Its therapeutic potential lies in its ability to enhance epithelial regeneration and mitigate damage in conditions like inflammatory bowel disease (IBD), acute liver injury, and pancreatitis. Preclinical studies highlight its efficacy in reducing mucosal inflammation and promoting tissue repair in animal models. However, IL-22's role is context-dependent; excessive or dysregulated signaling can exacerbate pathologies, such as psoriasis or certain cancers, by driving hyperproliferation or chronic inflammation.

Current research focuses on optimizing rIL-22 delivery and understanding its pleiotropic effects. Clinical trials explore its use in combination therapies or as a standalone treatment for gastrointestinal and metabolic disorders. Challenges include balancing its protective versus pro-inflammatory outcomes and minimizing off-target effects. Advances in protein engineering, such as PEGylation or fusion proteins, aim to improve its stability and bioavailability. As a therapeutic agent, rIL-22 represents a promising yet complex candidate, bridging immunology and regenerative medicine, with ongoing studies refining its clinical applications.
