A comprehensive review found the endocannabinoidome — a network of cannabinoid receptors, lipid mediators, and enzymes — shows promise for managing IBD complications in the joints, skin, liver, and eyes, not just intestinal inflammation.

What the researchers found
The endocannabinoidome (eCBome) includes receptors (CB1, CB2, GPR55, GPR35, PPARα, TRPV1), lipid mediators, and metabolic enzymes that modulate immune responses, gut barrier integrity, and systemic inflammation. Targeting eCBome may improve both intestinal inflammation and extraintestinal manifestations including arthritis, liver dysfunction, and dermatological disorders.
Why it matters
IBD is not just a gut disease — many patients suffer from joint, skin, liver, and eye complications that standard intestinal therapies do not address. The endocannabinoidome offers a unified therapeutic target for both local and systemic disease components.
The numbers in context
Receptors reviewed: CB1, CB2, GPR55, GPR35, PPARα, TRPV1. Extraintestinal targets: joints (arthritis), skin (dermatological disorders), liver (dysfunction), eyes. Multiple metabolic enzymes and lipid mediators assessed.
How the study worked
Comprehensive literature review across PubMed, Scopus, Web of Science, Science Direct, and Google Scholar. Focused on endocannabinoidome role in IBD and extraintestinal manifestations.
What this study cannot tell us
Narrative review without systematic methodology. Much evidence is preclinical. Clinical evidence for eCBome-targeting therapies in IBD extraintestinal manifestations is very limited. Complex system makes targeted drug development challenging.
How to read the evidence
Comprehensive narrative review identifying promising targets, but most evidence is preclinical and clinical validation is minimal.
When this study was published
2025 publication.
The bigger picture
Moving beyond the traditional focus on CB1 and CB2 receptors to the broader endocannabinoidome opens new therapeutic possibilities. Understanding the full network of cannabinoid-related signaling could lead to more targeted treatments with fewer side effects.
Questions still open
- Which eCBome targets are most clinically promising for IBD extraintestinal complications?
- Could a single eCBome-targeting drug address both intestinal and extraintestinal IBD?
Common questions
Can cannabinoids help with IBD joint pain?
Why does IBD cause problems outside the gut?
