Abstract
Botulinum neurotoxins (BoNTs) are the most toxic substances to mankind, and yet, there are no therapeutics available to reverse the paralysis, the deadly symptom of botulism caused by BoNTs. Here we report that RNA aptamer, selected through in vitro process against light chain of botulinum neurotoxin type A (BoNT/A) showed in vivo protection efficacy against botulism. Our results showed that RNA aptamer not only accelerated the recovery of local paralysis induced by BoNT/A through mouse exercise wheel assay, but also significantly delayed the time-to-death through mouse protection assay, and rescued one mouse (out of six) completely intoxicated by BoNT/A. Our results demonstrated the potential using RNA aptamer as antidote against deadly botulism.
