Abstract: Disclosed are embryonic stem cell-derived dendritic cells, genetically modified immature dendritic cells capable of maturation, as well as methods for the production of such cells. In one embodiment, the cells may be produced by a method comprising the steps of providing a population of embryonic stem cells; culturing the embryonic stem cells in the presence of a cytokine or combination of cytokines which brings about differentiation of the embryonic stem cells into dendritic cells; and recovering the dendritic cells from the culture. In a further embodiment, the cells may be genetically modified.

Abstract: This invention relates to an antibody which is a modified version of a therapeutic antibody with affinity for a cell-surface antigen, said antibody having reduced affinity for the antigen compared with the therapeutic antibody as a result of a modification or modifications to the antibody molecule, wherein the antibody is capable of inducing immunological tolerance to the therapeutic antibody. The invention further relates to a method of inducing immunological tolerance to a therapeutic antibody comprising administering to a patient an antibody which is a modified version of the therapeutic antibody and which has reduced affinity for the antigen as compared with the therapeutic antibody.

Abstract: The invention relates to the use of an antibody recognizing the Cdw52 antigen in the treatment of multiple sclerosis. Preferably, the antibody is the humanized antibody in the humanized antibody CAMPATH-1H.

Abstract: Tolerance to an antigen is induced in a subject by administering a non-depleting CD4 monoclonal antibody and a non-depleting CD8 monoclonal antibody. Tolerance to the antigen can be induced under cover of these antibodies. A depleting CD4 monoclonal antibody and/or a depleting CD8 monoclonal antibody may be administered prior to the non-depleting antibodies.

Abstract: Methods of treating patients suffering from, or at risk of developing, a leukocyte mediated disease comprising the administration of humanized antibodies and fragments thereof that bind human CD18 are disclosed.

Abstract: Humanized antibodies and fragments thereof that bind human CD18 are disclosed. Nucleic acids encoding anti-CD18 antibodies or fragments thereof, as well as expression vectors and host cells incorporating these nucleic acids for the recombinant expression of anti-CD18 antibodies are also encompassed by the invention. Pharmaceutical compositions comprising the antibodies of the invention are also disclosed.

Abstract: An antibody or antibody fragment with a binding affinity for the CD3 antigen, having a human constant region, and human or rat variable framework region, a heavy chain with CDRs having the amino acid sequences:(a) Ser-Phe-Pro-Met-Ala (SEQ ID NO:1),(b) Thr-Ile-Ser-The-Ser-Gly-Gly-Arg-Thr-Tyr-Tyr-Arg-Asp-Ser-Val-Lys-Gly (SEQ ID NO:2),(c) Phe-Arg-Gln-Tyr-Ser-Gly-Gly-Phe-Asp-Tyr (SEQ ID NO:3),and light chain with CDRs having the amino acid sequences:(d) Thr-Leu-Ser-Ser-Gly-Asn-Ile-Glu-Asn-Tyr-Val-His (SEQ ID NO:4),(e) Asp-Asp-Asp-Lys-Arg-Pro-Asp (SEQ ID NO:5),(f) His-Ser-Tyr-Val-Ser-Ser-Phe-Asn-Val (SEQ ID NO:6),in which the heavy chain CDRs are arranged in the order (a), (b), (c) in the leader.fwdarw.constant region direction and the light chain CDRs are arranged in the order (d), (e), (f) in the leader.fwdarw.constant region direction.

Abstract: An antibody is produced, which will bind effectively with the antigen Campath-1, and which has at least one complementarity determining region of rat origin, as identified in FIG. 2, which may be combined with a range of different foreign variable domain framework regions as desired, including framework regions of human origin.
