TB-500 vs LL-37: Head-to-Head Comparison
TB-500 and LL-37 both contribute to wound healing but through entirely different pathways. TB-500 promotes cell migration and tissue remodeling via actin regulation, while LL-37 fights infection at wound sites and recruits immune cells. They address complementary aspects of the healing process.
Side-by-Side Comparison
| Dimension | TB-500 | LL-37 |
|---|---|---|
| Evidence Level | Animal studies, limited human data | Endogenous human peptide, well-characterized biology |
| FDA Status | Not approved | Not approved as therapeutic |
| Mechanism | Actin sequestration, cell migration, angiogenesis | Antimicrobial membrane disruption, chemotaxis, immune modulation |
| Primary Use | Soft tissue repair, muscle recovery | Infection prevention, biofilm disruption, immune support |
| Wound Healing Role | Tissue remodeling and cell migration phase | Infection control and inflammatory phase |
| Side Effects | Head rush, temporary lethargy | Potential cytotoxicity at high doses |
Peptide Overviews
TB-500 (Thymosin Beta-4)
CPreclinicalTB-500 is a synthetic version of the naturally occurring peptide Thymosin Beta-4. It plays a role in cell migration, blood vessel formation, and tissue repair.
LL-37
CPreclinicalLL-37 is the only cathelicidin antimicrobial peptide found in humans. It plays a crucial role in innate immune defense, wound healing, and inflammation modulation.
