Tetanus Toxin P2 (830 – 844) – Immunology – Antigens/Epitotes/Pools/Librairies

Tetanus Toxin P2 (830 – 844) is a protein that is derived from the single-chain polypeptide neurotoxin produced by Clostridium tetani. The neurotoxins produced by Clostridium tetani are among the most potent molecules known to humankind. Once in the body, the toxin binds to the basal lamina at the neuromuscular junction. From here, the toxin is transported to inhibitory interneurons in the spinal cord, where it prevents the release of neurotransmitters, which causes spastic paralysis. The P2 protein has antigenic properties that are reflective of the neurotoxin released by Clostridium tetani. Therefore, P2 is a suitable epitopes for CD4+ T cells and can be used to stimulate the release of IFNg, which is a cytokine that promotes macrophage activity and coordinates lymphocyte endothelium interactions.
