Protocol notes
Oral delivery is a recurring practical challenge. BPC-157 has reported activity after oral gavage in rodents; KPV is typically encapsulated for colonic delivery; larazotide is designed for luminal action with minimal systemic absorption.
Mechanistic rationale
BPC-157 acts on mucosal angiogenesis and gastric protection. KPV suppresses NF-κB-driven cytokine release in mucosal cells. Larazotide modulates intestinal tight junctions through zonulin antagonism. Together they target healing, inflammation, and barrier integrity respectively.
Endpoint suggestions
Histological scoring (Wallace, Geboes), colon length, fecal calprotectin equivalents, intestinal permeability (lactulose/mannitol), and colonic cytokine concentrations are the standard endpoints in murine colitis models.
Confounders
Stress, microbiome variation, and vehicle pH can all dominate signal in gut models. Strict standardisation of housing, diet, and water source is essential.
