- Researchers selecting peptides for chronic inflammation studies must match peptide mechanism to experimental model and research question. The following table compares five peptides with distinct mechanisms and inflammatory targets.
- Thymosin Alpha-1
- Modulates TLR signaling on dendritic cells and macrophages; shifts M1 → M2 polarization
- TNF-α, IL-1β, IL-10 upregulation
- Sepsis, IBD, cytokine storm
- Best for testing macrophage polarization as an inflammation resolution mechanism
- KPV Tripeptide
- Inhibits NF-κB nuclear translocation at epithelial surfaces
- NF-κB, COX-2, iNOS
- Colitis, dermatitis, mucosal inflammation
- Best for studying local mucosal inflammation without systemic immune suppression
- BPC-157
- Stabilizes vascular endothelium via VEGFR2 and eNOS upregulation
- Angiogenesis, endothelial repair
- IBD, tendinopathy, wound healing
- Best for investigating vascular stability's role in inflammation resolution
- VIP (Vasoactive Intestinal Peptide)
- Activates VPAC receptors, increases cAMP, expands Tregs
- Th17 inhibition, IL-17, Treg expansion
- EAE (MS model), rheumatoid arthritis
- Best for autoimmune inflammation driven by Th17 pathways
- LL-37
- Binds bacterial endotoxins (LPS, LTA); modulates neutrophil chemotaxis
- TLR4, TLR2, antimicrobial activity
- Sepsis, chronic wounds, infection-driven inflammation
- Best for studying the intersection of infection and sterile inflammation
