<b>ToxT</b> is a molecule at the end of a transcriptional cascade that autoregulates the transcription of the primary virulence factors of <i>Vibrio cholerae</i>[http://en.wikipedia.org/wiki/Vibrio_cholerae] and itself. ToxT is a cytoplasmic protein that is activated in turn by ToxR, which is itself activated by ToxS in response to environmental stimuli.<ref>Kenneth Todar [http://www.textbookofbacteriology.net/cholera.html] ''Vibrio cholerae'' and Asiatic Cholera, Todar's Online Textbook of Bacteriology. Date of access: 2011-11-28.</ref> These two factors, cholera toxin (CT)[http://en.wikipedia.org/wiki/Cholera_toxin] and the toxin co-regulated pilus (TCP), are instrumental in causing the disease <b>cholera</b>[http://en.wikipedia.org/wiki/Cholera]. This is an intestinal infection resulting in massive water loss in the affected individual, causing extreme dehydration.[http://en.wikipedia.org/wiki/Cholera] Rehydration is sufficient as treatment. | <b>ToxT</b> is a molecule at the end of a transcriptional cascade that autoregulates the transcription of the primary virulence factors of <i>Vibrio cholerae</i>[http://en.wikipedia.org/wiki/Vibrio_cholerae] and itself.
