Publication number: 20080319167Abstract: This invention describes a novel agent for the targeted control of a mammalian cell activity, in particular the agent is 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 (with or without the Binding Site) from within the endosome across the endosomal membrane into the cytosol of the cell, 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: June 28, 2007Publication date: December 25, 2008Inventors: Keith Alan Foster, Michael John Duggan, Clifford Charles Shone

Patent number: 7368532Abstract: A non-toxic polypeptide, for delivery of a therapeutic agent to a neuronal cell, comprises a binding domain that binds to the neuronal cell, and a translocation domain that translocates the therapeutic agent into the neuronal cell, wherein the translocation domain is not a HN domain of a clostridial toxin and is not a fragment or derivative of a HN domain of a clostridial toxin.Type: GrantFiled: December 4, 2000Date of Patent: May 6, 2008Assignee: Syntaxin LimitedInventors: Clifford Charles Shone, John Mark Sutton, Nigel Silman

Patent number: 7192596Abstract: 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.Type: GrantFiled: September 12, 2002Date of Patent: March 20, 2007Assignee: The Health Protection Agency Ipsen LimitedInventors: Clifford Charles Shone, Conrad Padraig Quinn, Keith Alan Foster, John Chaddock, Philip Marks, J. Mark Sutton, Patrick Stancombe, Jonathan Wayne

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

Publication number: 20040208889Abstract: A polypeptide conjugate contains a bacterial injectable effector protein, secreted by a modified pilus or “needle-like” structure comprising a type m or type TV secretion apparatus, and a carrier that targets the conjugate to a target cell. The effector protein is used for a variety of purposes including treatment of neurodegenerative disease, intracellular infection and diseases associated with defects of secretion.Type: ApplicationFiled: May 26, 2004Publication date: October 21, 2004Inventors: John Mark Sutton, Clifford Charles Shone

Patent number: 6461617Abstract: A polypeptide has first and second domains which enable the polypeptide to be translocated into a target cell or which increase the solubility of the polypeptide, or both, and further enable the polypeptide to cleave one or more vesicle or plasma-membrane associated proteins essential to exocytosis. 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.
