Peptides for Chronic Inflammation & Inflammatory Conditions
Chronic low-grade inflammation underlies most age-related disease — from cardiovascular to neurodegenerative to autoimmune conditions. Several peptides modulate inflammatory pathways directly, offering targeted intervention beyond conventional NSAIDs and corticosteroids.
How peptide Targets Peptides for Inflammation
Anti-inflammatory peptides work through diverse mechanisms:
**NF-κB suppression (KPV, BPC-157):** NF-κB is the master transcription factor for inflammatory cytokines (IL-1β, IL-6, TNF-α). KPV (alpha-MSH fragment) is one of the most potent NF-κB suppressors identified — it directly blocks the nuclear translocation of the NF-κB complex. BPC-157 also reduces NF-κB-driven inflammation, particularly in the GI tract.
**Immune modulation (Thymosin Alpha-1, LL-37):** Rather than broadly suppressing inflammation, these peptides modulate immune balance — enhancing regulatory T-cell function and shifting from Th1/Th17 inflammatory dominance toward Th2/Treg tolerance. This is particularly relevant for autoimmune-driven inflammation.
**Mitochondrial anti-inflammatory (SS-31, MOTS-c):** Mitochondrial dysfunction drives sterile inflammation through DAMP release and inflammasome activation. SS-31 stabilizes mitochondrial membranes; MOTS-c activates AMPK which suppresses inflammatory signaling. Both address the mitochondrial root of age-related inflammation ('inflammaging').
**Resolution promotion (BPC-157):** Rather than just suppressing initiation, BPC-157 appears to promote the resolution phase of inflammation — the active biological program that clears inflammatory mediators and initiates tissue repair.
Recommended Peptides (6)
BPC-157
Research-Grade
A 15-amino-acid peptide fragment derived from gastric juice protein BPC, studied extensively in animal models for tissue healing and gut integrity.
KPV
Research-Grade
A C-terminal tripeptide fragment of alpha-MSH with potent anti-inflammatory activity, studied for its role in modulating NF-κB signaling without melanogenic effects.
LL-37
Research-Grade
A 37-amino-acid human cathelicidin antimicrobial peptide with broad-spectrum activity against bacteria, fungi, and biofilms, plus immunomodulatory and wound-healing properties.
MOTS-c
Research-Grade
A 16-amino-acid peptide encoded in the mitochondrial 12S rRNA — investigated as a metabolic regulator of AMPK signaling and insulin sensitivity.
SS-31 (Elamipretide)
Research-Grade
A cell-permeable tetrapeptide that targets the inner mitochondrial membrane, stabilizing cardiolipin and improving electron transport chain efficiency — in late-stage clinical trials for mitochondrial and cardiac diseases.
Thymosin α1
Zadaxin
A 28-amino-acid thymic peptide approved in 30+ countries (not US) for hepatitis B/C and as an immune adjunct in oncology and infectious disease.
