Publication number: 20120141511Abstract: A novel agent for the targeted control of a mammalian cell activity can be used to control the interaction of particular cell types with their external environment. The agent has applications as a pharmaceutical for the treatment of a variety of disorders. An agent according to the invention comprises three Domains B, T and E, linked together in the following manner: Domain B-Domain T-Domain E where Domain B is the Binding Domain, which binds the agent to a Binding Site on the cell which undergoes endocytosis to produce an endosome; Domain T is the Translocation Domain, which translocates the agent from within the endosome across the endosomal membrane into the cytosol of the cell; and Domain E is the Effector Domain, which inhibits the ability of the Recyclable Membrane Vesicles to transport the Integral Membrane Proteins to the surface of the cell.Type: ApplicationFiled: October 11, 2011Publication date: June 7, 2012Inventors: Keith Alan Foster, Michael John Duggan, Clifford Charles Shone

Patent number: 7452543Abstract: 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, particular chronic pain.Type: GrantFiled: October 25, 2005Date of Patent: November 18, 2008Assignee: Syntaxin Ltd.Inventors: John Andrew Chaddock, Philip Marks, Michael John Duggan

Patent number: 6962703Abstract: 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.Type: GrantFiled: May 20, 2002Date of Patent: November 8, 2005Assignees: Ipsen Limited, Health Protection AgencyInventors: Keith Alan Foster, Michael John Duggan, Clifford Charles Shone
