    Abstract: The OX-40 antigen is characterized and claimed together with variants and derivatives thereof. Also described are binding agents for the antigen and the use of these in diagnosis and therapy. Examples of such use include a method for the selective depletion of activated CD4+ T-cells in vivo by using immunotoxins comprising an OX-40 antibody conjugated to a toxic molecule (such as Ricin-A chain). The administration of these specific immunotoxins is used therapeutically to deplete autoimmune reactive CD4+ T-cells which have been implicated in diseases including Multiple Sclerosis, Rheumatoid Arthritis, Sarcoidosis, and Autoimmune Uveitis as well as inflammatory bowel disease and graft-versus-host disease. This type of therapy is also beneficial for eradicating CD4+ T-cell lymphomas and alloreactive CD4+ T-cells involved with a transplantation reaction. The use of the human form of the OX-40 antibody will also help in the early diagnosis of all the diseases mentioned above.

  • Patent number: 6287817
    Abstract: A protein conjugate consisting of antibody directed at the pIgR and A1AT can be transported specifically from the basolateral surface of epithelial cells to the apical surface. This approach provides us with the ability to deliver a therapeutic protein directly to the apical surface of the epithelium, by targeting the pIgR with an appropriate ligand. Thus, the highest concentration of the antiprotease will be at the apical surface, where it can do the greatest good in accelerating the inflammatory response.

  • Patent number: 6172197
    Abstract: A member of a specific binding pair (sbp) is identified by expressing DNA encoding a genetically diverse population of such sbp members in recombinant host cells in which the sbp members are displayed in functional form at the surface of a secreted recombinant genetic display package (rgdp) containing DNA encoding the sbp member or a polypeptide component thereof, by virtue of the sbp member or a polypeptide component thereof being expressed as a fusion with a capsid component of the rgdp. The displayed sbps may be selected by affinity with a complementary sbp member, and the DNA recovered from selected rgdps for expression of the selected sbp members. Antibody sbp members may be thus obtained, with the different chains thereof expressed, one fused to the capsid component and the other in free form for association with the fusion partner polypeptide. A phagemid may be used as an expression vector, with said capsid fusion helping to package the phagemid DNA.

  • Patent number: 6072041
    Abstract: A protein conjugate consisting of antibody directed at the pIgR and A.sub.1 AT can be transported specifically from the basolateral surface of epithelial cells to the apical surface. This approach provides us with the ability to deliver a therapeutic protein directly to the apical surface of the epithelium, by targeting the pIgR with an appropriate ligand. Thus, the highest concentration of the antiprotease will be at the apical surface, where it can do the greatest good in accelerating the inflammatory response.

  • Patent number: 6042828
    Abstract: Chimeric human antibody expression vectors are constructed by inserting the antibody heavy chain variable region-encoding cDNA and antibody light chain variable region-encoding cDNA isolated from hybridomas producing a mouse or rat monoclonal antibody reacting with the ganglioside GM.sub.2 respectively into an expression vector for use in animal cells which contains the human antibody heavy chain constant region- or human antibody light chain constant region-encoding cDNA. The expression vectors are introduced into animal cells and the transformant thus obtained is cultured for the production of a chimeric human antibody reacting with the ganglioside GM.sub.2.

  • Patent number: 5990297
    Abstract: A human monoclonal antibody specifically binding to a surface antigen of cancer cell membrane, an isolated DNA encoding the antibody, and a hybridoma producing the antibody. An anti-cancer formulation comprising the monoclonal antibody bonded to the surface of a liposome enclosing an anti-cancer agent or toxin is also provided.

  • Patent number: 5969108
    Abstract: A member of a specific binding pair (sbp) is identified by expressing DNA encoding a genetically diverse population of such sbp members in recombinant host cells in which the sbp members are displayed in functional form at the surface of a secreted recombinant genetic display package (rgdp) containing DNA encoding the sbp member or a polypeptide component thereof, by virtue of the sbp member or a polypeptide component thereof being expressed as a fusion with a capsid component of the rgdp. The displayed sbps may be selected by affinity with a complementary sbp member, and the DNA recovered from selected rgdps for expression of the selected sbp members. Antibody sbp members may be thus obtained, with the different chains thereof expressed, one fused to the capsid component and the other in free form for association with the fusion partner polypeptide. A phagemid may be used as an expression vector, with said capsid fusion helping to package the phagemid DNA.

  • Patent number: 5885793
    Abstract: Methods are disclosed for the production of anti-self antibodies and antibody fragments, being antibodies or fragments of a particular species of mammal which bind self-antigens of that species. Methods comprise providing a library of replicable genetic display packages (rgdps), such as filamentous phage, each rgdp displaying at its surface a member of a specific binding pair which is an antibody or antibody fragment, and each rgdp containing nucleic acid sequence derived from a species of mammal. The nucleic acid sequence in each rgdp encodes a polypeptide chain which is a component part of the sbp member displayed at the surface of that rgdp. Anti-self antibody fragments are selected by binding with a self antigen from the said species of mammal. The displayed antibody fragments may be scFv, Fd, Fab or any other fragment which has the capability of binding antigen. Nucleic acid libraries used may be derived from a rearranged V-gene sequences of unimmunised mammal.
