75 results about "Clostridial Neurotoxin" patented technology

Clostridial neurotoxins (CNT), a family of closely related bacterial protein toxins, consist of seven antigenically distinguishable botulinum neurotoxins (BoNTs) and tetanus neurotoxin (TeNT). Each CNT is synthesized as a ~150 kDa single chain protein, but subsequently cleaved by specific clostridial or host proteases.

Conjugates of galactose-binding lectins and clostridial neurotoxins as analgesics

InactiveUS7052702B1Pain reliefReduce and preferably prevent transmissionNervous disorderBacteriaGalactose binding lectinProtein translocation
A class of novel agents that are able to modify nociceptive afferent function is provided. The agents may inhibit the release of neurotransmitters from discrete populations of neurones and thereby reduce or preferably prevent the transmission of afferent pain signals from peripheral to central pain fibers. They comprise a galactose-binding lectin linked to a derivative of a clostridial neurotoxin. The derivative of the clostridial neurotoxin comprises the L-chain, or a fragment thereof, which includes the active proteolytic enzyme domain of the light (L) chain, linked to a molecule or domain with membrane translocating activity. The agents may be used in or as pharmaceuticals for the treatment of pain, particularly chronic pain.

Clostridial neurotoxins for use in wound healing

Naturally occurring and / or modified Clostridium neurotoxins, including those neurotoxins free of complexing proteins which naturally form complexes with Clostridial neurotoxins, are used to enhance healing of injured surface or superficial tissue of a patient by local administration into or in close proximity to the injured tissue. Such neurotoxins may be advantageously employed in wound healing and preventing scar formation, and find applicability in the area of ophthalmology, e.g. in treatment of injured corneal tissue, for example by closing inflamed eyes. A further embodiment includes diagnostic usage for the evaluation of effective toxin administration and medicaments for use therein.
