Abstract:
The invention is directed to a compound comprising one or more CD1d complexes in association with an antibody specific for a cell surface marker. The CD1d complexes comprise a CD1d, a β2-microglobulin molecule, and may further comprise an antigen bound to the CD1d binding groove. The invention is further directed to methods of inhibiting or stimulating an immune response with the CD1d-antibody compounds, in particular anti-tumor and autoimmunity responses.

Abstract:
The invention is directed to methods of modulating an immune response in an animal, comprising administering a composition comprising one or more soluble CD1d complexes, in particular non-specific soluble CD1d complexes. Soluble CD1d complexes comprise a soluble CD1d polypeptide, a β2-microglobulin polypeptide, and a ceramide-like glycolipid antigen bound to the CD1d antigen binding groove, and in certain embodiments, an immunogen. The administration of compositions of the present invention affects the activity of CD1d-restricted NKT cells, and in particular, allows for multiple administrations without causing CD1d-restricted NKT cell anergy.
Abstract:
The invention relates to multispecific antibody constructs comprising Fab fragments having mutations at the interface of the CH1 and CL domains, said mutations preventing heavy/light chain mispairing.
Abstract:
The present invention relates to a pharmaceutical composition representing a novel immunomodulating principle comprising bacterial endotoxin, fetal hemoglobin or more particularly a heme-free derivative or the γ-chain thereof, and optionally, components which are present in the fetal liver in addition to HbF. The composition is delivered to humans in a pharmaceutically acceptable carrier and/or diluent. In accordance with the present invention it was surprisingly found that endotoxin and fetal hemoglobin partial structures display a pronounced synergistic biomedical activity. The biomedical effect of fetal hemoglobin and its partial structures is surprisingly not based on a classical hemoglobin function as an oxygen transporter but related to a modulation of endotoxin-mediated bioactivity. This biomedical activity is surprisingly also observed after oral application of the composition. The composition of the invention finds a variety of applications which have in common the stimulation of the immune system and the reversion in polarization of cytokines and chemokines from a Th2-directed response to a Th1-type response. The proposed applications would therefore include the treatment of allergic conditions, malignancies, chronic infections, autoimmune phenomena and age-related imbalances.

Abstract:
The invention concerns novel monoclonal antibodies with high specificity to and affinity for human carcinoembryonic antigen (CEA), derivatives thereof, processes for the preparation of these antibodies and their derivatives, hybridoma cell lines secreting the antibodies, and processes for the preparation of said cell lines. The monoclonal antibodies of the invention and their derivatives are useful in the diagnosis and therapy of cancer and serial monitoring of cancer patients for recurrent disease or response to therapy. Test kits and pharmaceutical compositions containing said monoclonal anti-CEA antibodies are also subject of the invention.
Abstract:
The present invention concerns an oligomer comprising more than 2 units, wherein each unit comprises a peptidic domain capable of oligomerizing and a domain capable of binding to an acceptor (ligand), wherein the oligomerizing domain is not an antibody or a functional antibody fragment from the constant region. Also described is the use and synthesis of this oligomer.
