Clostridium tetani Virulence Factors and Pathophysiology in Cellular Biology
The core theoretical principle is that *Clostridium tetani* pathogenesis is driven by the retrograde transport and enzymatic activity of the neurotoxin tetanospasmin, a zinc-dependent metalloprotease that specifically cleaves synaptic vesicle-associated SNARE proteins (synaptobrevin). This molecular mechanism prevents the exocytosis of inhibitory neurotransmitters gamma-aminobutyric acid (GABA) and glycine within the central nervous system. Consequently, the absence of neuronal inhibition leads to uninhibited alpha-motor neuron excitation, resulting in generalized muscle rigidity and spasms characteristic of tetanus.
