IL-36 cytokines and gut immunity

Area of Science:

• Immunology
• Gastroenterology
• Cytokine Biology

Background:

• Interleukin 36 (IL-36) is part of the IL-1 superfamily, implicated in inflammatory disorders.
• IL-36 cytokines exhibit complex roles in the gastrointestinal tract, with overexpression noted in colitis models and IBD patients.
• The IL-36 family includes agonists (IL-36α, IL-36β, IL-36γ) and antagonists (IL-36Ra, IL-38) that interact with the IL-36 receptor.

Purpose of the Study:

• To review the processing and secretion of IL-36 cytokines.
• To elucidate the immunological effects of IL-36 within the gut.
• To discuss current therapeutic strategies targeting IL-36R signaling for chronic intestinal inflammation.

Main Methods:

• Literature review on IL-36 cytokine processing, secretion, and immunological functions.
• Analysis of existing research on IL-36's role in gut immunity and inflammatory conditions.
• Overview of ongoing clinical trials investigating IL-36R pathway inhibition.

Main Results:

• IL-36 cytokines have context-dependent roles, potentially contributing to or protecting against gut inflammation.
• IL-36 receptor agonists bind to IL-36R, mediating diverse effects in inflammatory settings.
• Evidence suggests IL-36 dysregulation is involved in the pathogenesis of inflammatory bowel disease (IBD).

Conclusions:

• IL-36 signaling presents a promising target for therapeutic intervention in chronic intestinal inflammation.
• Further research is needed to fully understand the multifaceted roles of IL-36 in gut immunity.
• Exploring unanswered questions in IL-36 research may lead to novel treatment strategies for IBD.
