Patent number: 6692743Abstract: Although the mechanism of induction of apoptosis through antibody dependent cellular cytotoxicity (ADCC) mediated by NK cells is well understood, little is known about the fate of the reactive NK cells. Nevertheless, it has been shown that NK cells previously activated by IL-2, but not naive NK cells, died by apoptosis after Fc&ggr;RIIIa crosslinking, or after engagement in cytolytic functions. It is demonstrated that apoptosis of naive NK cells is also observed after stimulation with a rat IgG2b anti CD2 mAb (LO-CD2a/BTI-322) or anti HLAI (LO-HLA-1)mAb. The NK apoptosis is rapid (within minutes), Fas-ligand and mRNA synthesis independent and does not require a cell contact. The intracellular mechanism of NK cell apoptosis is calcium, PKC and PLA2 dependent but calcineurin and P13 kinase independent. We suggest that NK cell apoptosis results from the crosslinking on the same cell surface of CD2 or HLA-I molecules and Fc&ggr;RIIIa that exhibits a high affinity for the rat IgG2b isotype.Type: GrantFiled: May 4, 1999Date of Patent: February 17, 2004Assignee: Universite Catholique de LouvainInventors: Herve Bazin, Dominique Latinne

Patent number: 6576236Abstract: When stimulated through the T cell receptor(TCR)/CD3 complex without requisite costimulation through the CD28/B7 interaction, T cells enter a state of antigen specific unresponsiveness or anergy.

Patent number: 6475749Abstract: Rh antibody hybrids for use in testing red blood cells for the presence of one or more Rh factors. The Rh hybrid antibody may also be used in therapeutic procedures which require the use of Rh antisera. The hybrid antibody includes an IgG anti-Rh antibody which has a polymeric tailpiece attached to the carboxy terminal end of each of the IgG antibody heavy chains. A hemagglutinin method is provided for Rh phenotyping in which agglutination of Rh-positive red blood cells is achieved in a one-step process involving addition of the hybrid Rh antisera to the red blood cells being tested.Type: GrantFiled: August 11, 1999Date of Patent: November 5, 2002Assignee: The Regents of the University of CaliforniaInventors: Sherie L. Morrison, Ramon MontaƱo

Patent number: 6458934Abstract: The present invention is directed to humanized antibodies that specifically bind the protein 4-1BB. The antibodies can be made by grafting of the complementarity determining regions (CDR's) of mouse monoclonal antibody to human 4-1BB to the remaining portions of a human antibody and by making further amino acid replacements. In addition, a pharmaceutical composition that includes the humanized antibody can be made and can be used to treat autoimmune diseases to suppress an immune response. The humanized antibody of the invention has high affinity for human 4-1BB, and exhibits sequence similarity to human antibody. As a result, the pharmaceutical composition of the present invention can be used to treat autoimmune disease and act as an immunosuppressant in humans without much side-effect.Type: GrantFiled: November 12, 1999Date of Patent: October 1, 2002Assignee: LG Chemical LimitedInventors: Hyo Jeong Hong, Sung Sup Park, Young Jun Kang, Chang-Yuil Kang, Sung Kwan Yoon
