Tetanus and botulinum neurotoxins cause neuroparalysis by inhibiting neuroexocytosis. They are composed by two main chains: the 100 kDa heavy chain (H) mediates the neurospecific binding to target cells and chaperons the entry of the 50 kDa light chain (L). After binding on the plasma membrane, these neurotoxins enter into nerve terminals via endocytosis inside synaptic vesicles, as shown here for the first time by immuno-electron microscopy. The lumenal acidic pH induces a structural change of the neurotoxin molecule that becomes capable of translocating its L chain into the cytosol, via a transmembrane protein-conducting channel made by the H chain. This is the least understood step of the intoxication process primarily because it takes p...
