Tetanus Toxoid Helper Epitope (TT830-844)
- Target
- TT830-844
- Molecular classification
- Peptide, Epitope
01
Overview
The tetanus toxoid helper epitope (TT830-844) is a peptide segment derived from the inactivated tetanus toxin of *Clostridium tetani*. It functions as a universal T-helper cell epitope in vaccine development, inducing CD4+ T-cell activation and enhancing immune responses against weakly immunogenic antigens. It is broadly recognized across diverse human populations and has been used safely in clinical trials as part of cancer vaccines and other immunotherapies.
