Laboratory studyHumans

Design
Laboratory study
Subjects
Caco-2 cell cultures and human colon tissue explants from bowel cancer, inflammatory bowel disease and appendicitis resections
Dose used in the study
Palmitoylethanolamide or cannabidiol at 10 micromolar in culture, with an inflammatory stimulus
Duration
Tissue culture
What was measured
Nine intracellular signalling phosphoproteins; cytokine secretion; receptor antagonist studies

What the authors reported

Palmitoylethanolamide reduced inflammatory signalling in cells and explants and prevented the rise in cytokine release in explant colon, an effect blocked by a PPAR-alpha antagonist. It was anti-inflammatory in both inflammatory bowel disease and appendicitis tissue.

Limits of this study

Tissue culture, not a treatment study. The cytokine effect appeared in explants but not in the cell line. The same group's later human permeability trial is Couch 2019. Independent academic group.
