  • Publication number: 20080213820
    Abstract: The invention relates to a method for determining the quantity of pre-synaptic neuromuscular blocking substance (notably botulinum toxin) contained in a sample. In one aspects, the method comprises the following steps: (i) determining the minimum voltage Vmsm needed to induce the contraction of a smooth muscle tissue, said smooth muscle tissue being linked to an electrical stimulator through an electrically conducting liquid and preferably immersed in an oxygenated physiological buffer containing glucose; (ii) adding the sample containing the pre-synaptic neuromuscular blocking substance; (iii) electrically stimulating, at a voltage at least equal to Vmsm the smooth muscle tissue at certain time intervals; (iv) comparing the effect induced by the sample to the effect induced by a reference substance and thereby determining the quantity of the pre-synaptic neuromuscular blocking substance in the sample.

  • Publication number: 20070248626
    Abstract: A single polypeptide is provided which comprises first and second domains. The first domain enables the polypeptide to cleave one or more vesicle or plasma-membrane associated proteins essential to exocytosis, and the second domain enables the polypeptide to be translocated into a target cell or increases the solubility of the polypeptide, or both. The polypeptide thus combines useful properties of a clostridial toxin, such as a botulinum or tetanus toxin, without the toxicity associated with the natural molecule. The polypeptide can also contain a third domain that targets it to a specific cell, rendering the polypeptide useful in inhibition of exocytosis in target cells. Fusion proteins comprising the polypeptide, nucleic acids encoding the polypeptide and methods of making the polypeptide are also provided. Controlled activation of the polypeptide is possible and the polypeptide can be incorporated into vaccines and toxin assays.

    Abstract: The invention relates to a method for determining the quantity of pre-synaptic neuromuscular blocking substance (notably botulinum toxin) contained in a sample. In one aspects, the method comprises the following steps: (i) determining the minimum voltage Vm needed to induce the contraction of muscle tissue, said muscle tissue being connected to an electrical stimulator through a motor nerve and preferably immersed in an oxygenated physiological buffer containing glucose; (ii) adding the sample containing the pre-synaptic neuromuscular blocking substance; (iii) electrically stimulating, at a voltage at least equal to Vm, the muscle tissue at certain time intervals; (iv) comparing the effect induced by the sample to the effect induced by a reference substance and thereby determining the quantity of the pre-synaptic neuromuscular blocking substance in the sample.

  • Patent number: 7052702
    Abstract: 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.

  • Patent number: 6962703
    Abstract: The invention relates to an agent specific for peripheral sensory afferents. The agent may inhibit the transmission of signals between a primary sensory afferent and a projection neutron by controlling the release of at least one neurotransmitter or neuromodulator from the primary sensory afferent. The agent may be used in or as a pharmaceutical for the treatment of pain, particularly chronic pain.
