摘要:
The present invention provides for methods of modulating the degradation rate of a toxin in a cell, thereby modulating the half-life of the toxin. Particularly, the invention features methods of modulating the degradation rate of a toxin by modulating fusion between a lysosome and an endosome that carries the toxin in the cell.
摘要:
The present invention relates to methods of manufacturing a di-chain botulinum toxin, wherein the methods do not involve the process of producing a single chain botulinum toxin that is followed by nicking to form a di-chain botulinum toxin.
摘要:
The present invention is directed to methods of altering the degree of internalization of a Clostridial toxin; methods of preventing or treating botulinum toxin intoxication; methods of treating metabolic disorders, muscular disorders, nervous system disorders, and/or pain conditions; methods of inhibiting the formation of lipid rafts on cell membranes; methods of treating a disease associated with lipid rafts; and methods of identifying a compound that alters the internalization of a Clostridial toxin.
摘要:
The present invention relates to rescue agents for use in the treatments of toxin intoxication—for example botulinum intoxication, which can result from food poisoning, an act of bioterrorism, or from accidental overdose in the course of treatment. In some embodiments, the rescue agents comprise at least one of an inactive botulinum toxin and a modified nontoxic nonhemagglutinin. The present invention also provides for glycosylated active and inactive toxins and methods of using same.
