  • Publication number: 20100297103
    Abstract: Disclosed is an antibody having an enhanced ADCC activity. Also disclosed is a method for producing the antibody. It was attempted to advance the technique of the amino acid mutation in an Fc region established by researchers of Genentech Inc. or the like, and a study was made on whether or not the ADCC activity can be enhanced by the mutation of an amino acid residue in an Fc region into cysteine (Cys) which may cause a drastic structural change that cannot be drawn by a computational search. As a consequence, a chemeric antibody is provided which has the mutation of an amino acid residue at least one position selected from the group consisting of 286th, 287th, 288th, 289th, 290th, 291st, 292nd, 294th, 298th, 301st, 302nd, 303rd, 305th, 306th, 307th, 308th and 309th positions into a Cys residue in an H-chain constant region.

  • Publication number: 20100028946
    Abstract: Fusion partner cells that enable production of heterohybridomas even from cells of species other than mouse were produced by fusing myeloma cells derived from a first animal species with leukemia cells derived from a second animal species, which have an extra S phase in the cell cycle and have the property of diploidizing. Stable production of substances can be achieved by producing heterohybridomas through cell fusion between the fusion partner cells and substance-producing cells of an animal other than mouse.

    Abstract: An objective of the present invention is to provide methods for selecting candidate peptides presented on the surface of cancer cells following binding to MHC class I molecules, wherein the peptides are involved in the stimulation of T cell immunity (cellular immunity). The present inventors discovered a new principle of MHC I-mediated antigen presentation in which a T cell antigen epitope is more efficiently presented on MHC I molecules when it is positioned at the N-terminal side than when positioned at the C-terminal side.
