- KPV (tripeptide)
- IκB stabilization. Prevents NF-κB nuclear translocation
- Direct transcription inhibition
- Receptor-independent (passive diffusion)
- Minimal. Compartmentalized effect
- Broad (any cell expressing NF-κB pathway)
- Corticosteroids (dexamethasone)
- Glucocorticoid receptor activation → IκB transcription
- Indirect (increases inhibitor levels)
- Requires glucocorticoid receptor
- High. Suppresses adaptive immunity
- Non-selective (affects all glucocorticoid-responsive cells)
- NSAIDs (ibuprofen)
- COX enzyme inhibition
- None. Acts downstream of transcription
- Enzyme-targeted
- Low (GI/renal toxicity instead)
- COX-1/COX-2 expressing cells only
- TNF-α biologics (adalimumab)
- Antibody neutralization of single cytokine
- None. Blocks one effector molecule
- Cytokine-specific binding
- Moderate. Infection risk from TNF blockade
- TNF-producing/responsive cells only
- α-MSH (full peptide)
- Melanocortin receptor agonism (MC1R/MC3R/MC5R)
- Indirect via cAMP → CREB pathway
- Requires melanocortin receptors
- Low
- Melanocortin receptor-expressing cells only
- Professional Assessment
- KPV offers upstream gene transcription control without receptor limitations. Filling the mechanistic gap between broad immunosuppression (steroids) and single-target biologics. The stabilization of IκB rather than receptor blockade explains why kpv mechanism studies show efficacy across tissue types that don't express melanocortin receptors. Trade-off: requires higher local concentrations than receptor-mediated compounds.
