Science Translational Medicine by Patrick McNutt, PhD, of the Wake Forest Institute for Regenerative Medicine.
Furthermore, in a companion article, an independent team demonstrated that a related drug has robust efficacy in mice.
This is one of those serendipitous moments in science where two groups, working independently, demonstrate similar results for a long-standing problem, McNutt said.
We are currently modifying this drug to enhance its therapeutic properties against botulism and exploring whether the same approach can be repurposed to treat other neuronal diseases.
In 2010, Konstantin Ichtchenko (New York University School of Medicine) conceived of a novel trojan horse strategy to treat botulism. This strategy is based on using a non-toxic form of BoNT to deliver therapeutic antibodies to paralyzed neurons, blocking wild-t ....

Non-toxic versions of botulism toxins can deliver therapeutic antibodies to treat botulism


Non-toxic versions of botulism toxins can deliver therapeutic antibodies to treat botulism
Taking advantage of the chemical properties of botulism toxins, two teams of researchers have fashioned non-toxic versions of these compounds that can deliver therapeutic antibodies to treat botulism, a potentially fatal disease with few approved treatments.
The research, which was conducted in mice, guinea pigs, and nonhuman primates, suggests that the toxin derivatives could one day offer a platform to quickly treat established cases of botulism and target hard-to-reach molecules within neurons. Botulism manifests due to bacterial toxins called botulinum neurotoxins (BoNTs), which are the most potent toxins known to humans. ....

New strategy to fight botulinum toxin - expert available


Related to new research published in the January issue of
Science Translational Medicine, Patrick McNutt, PhD, of the Wake Forest Institute for Regenerative Medicine, was part of the research team that demonstrated a new Trojan horse approach that produces strong antidotal efficacy in treating lethal botulism in mice, guinea pigs and rhesus macaque monkeys.
Furthermore, in a companion article, an independent team demonstrated that a related drug has robust efficacy in mice.
This is one of those serendipitous moments in science where two groups, working independently, demonstrate similar results for a long-standing problem, McNutt said.
