This comparison does not assign a generated winner or score.
- Thymalin
- Upregulates Foxp3 transcription in thymic epithelium → increases CD4+CD25+Foxp3+ Treg differentiation
- Thymic stromal cells, T-regulatory precursors
- 4–6 weeks (Treg population expansion is slow)
- Systemic lupus, autoimmune thyroiditis, rheumatoid arthritis
- Best for upstream immune reprogramming where Treg dysfunction is primary. Ineffective in conditions driven by gut antigen exposure or established cytokine storms
- BPC-157
- Activates FAK-paxillin pathway → stabilises claudin-1/occludin tight junctions
- Intestinal epithelial cells, gastric mucosa
- 7–14 days (tight junction protein expression)
- Inflammatory bowel disease, ankylosing spondylitis, celiac-associated autoimmunity
- Essential when gut permeability is implicated. Less relevant in autoimmune conditions without GI involvement (e.g., Hashimoto's, MS)
- KPV
- Inhibits NF-κB translocation by stabilising IκB-α → blocks pro-inflammatory cytokine transcription
- All nucleated cells (mechanism is ubiquitous)
- 2–4 hours (immediate cytokine suppression)
- Ulcerative colitis, psoriasis, rheumatoid arthritis
- Fastest-acting but shortest half-life. Ideal for acute flare management, less suitable as monotherapy for chronic autoimmune conditions requiring sustained modulation
