KPV in experimental colitis
PepT1-mediated tripeptide KPV uptake reduces intestinal inflammation
Dalmasso G et al. · Gastroenterology
Study record
- Population
Human-derived intestinal and T-cell lines; female C57BL/6 mice aged 8 weeks.
Read source · Full-text reportMaterials and methods — Cell culture and Animals- Formulation
KPV reagent was purchased from Biopeptide; radiolabeled KPV for uptake assays came from Sibtech. These are experimental reagents, not evidence for a commercial KLOW formulation.
Read source · Supplementary materialMaterials and methods — Reagents, PDF page 1- Route
Drinking water in mice; exposure in cell culture.
Read source · Full-text reportMaterials and methods; Figures 6 and 8- Dose & frequency
The in-vivo experiments used a KPV concentration of 100 μM. Concentration is not a body-weight dose; no human or KLOW regimen is established.
Read source · Full-text reportDiscussion — rationale for in-vivo concentration- Study design
Cell experiments and DSS/TNBS mouse-colitis models with KPV and control groups.
Read source · Full-text reportMaterials and methods; Figures 6 and 8- Duration
Inflammation was assessed 8 days after DSS treatment or 48 hours after TNBS administration. These are model-specific assessment times, not human treatment cycles.

Reduced inflammatory signaling in cells and inflammatory measures in mouse models.
Read source · Full-text reportResults; Figures 1, 6–8- Adverse events
Human safety was not evaluated: this was a cell and mouse study. Experimental inflammation outcomes do not establish clinical safety.
Read source · Full-text reportMaterials and methods — Cell culture, Animals and Induction of colitis- Monitoring
Experimental inflammation assessment used histology and pro-inflammatory cytokine expression. These are research endpoints, not human safety monitoring.

What it supports
Mechanistic and preclinical evidence about KPV.
What it does not establish
Not a human clinical trial. Does not establish efficacy, dosing, or safety of KLOW. Sample sizes differ by experiment: Figure 6 reports 5 mice per group, Figure 8 reports 10; the general methods statement of 10 per group should not be applied to every experiment.
