摘要:
The invention relates to aglycosyl anti-CD154 antibodies or antibody derivatives, characterized by a modification at the conserved N-linked site in the CH2 domains of the Fc portion of said antibody. The invention also relates to the treatment of immune response related diseases and inhibition of unwanted immune responses with such aglycosylated anti-CD154 antibodies or antibody derivatives thereof.
摘要:
The present invention relates to methods for designing and producing novel CD40:CD154 binding interrupter compounds and methods using these compounds to treat conditions associated with inappropriate CD154 activation in a subject. This invention also relates to novel methods for screening candidate compounds for the properties of specifically binding CD154 and interrupting CD40:CD154 interaction. This invention further relates to methods of improving the binding affinity, or the ability to block CD40/CD154 interaction, of a synthetic molecule for a trimeric protein, such as CD154. These methods comprise converting a first synthetic molecule that cannot promote lattice or aggregate formation of its target trimeric protein to a second synthetic molecule that can promote lattice or aggregate formation of its target trimeric protein. This invention also relates to a two-dimensional lattice or aggregate comprising a plurality of trimeric CD154 on a cell surface or in solution, wherein the lattice or aggregate is formed by bivalent anti-CD154 antibodies associated with trimeric CD154 molecules.

This invention relates to compositions and methods useful for activating LT-β receptor signaling, which in turn elicits potent anti-proliferative effects on tumor cells. More particularly, this invention relates to lymphotoxin heteromeric complexes formed between lymphotoxin-α and multiple subunits of lymphotoxin-β, which induce cytotoxic effects on tumor cells in the presence of lymphotoxin-β receptor activating agents. Also within the scope of this invention are antibodies directed against the lymphotoxin-β receptor which act as lymphotoxin-β receptor activating agents alone or in combination with other lymphotoxin-β receptor activating agents either in the presence or absence of lymphotoxin-α/β complexes. A screening method for selecting such antibodies is provided. This invention also relates to compositions and methods using cross-linked anti-lymphotoxin-β receptor antibodies either alone or in the presence of other lymphotoxin-β receptor activating agents to potentiate tumor cell cytotoxicity.
摘要:
This invention relates to compositions and methods comprising “lymphotoxin-β receptor blocking agents”, which block lymphotoxin-β receptor signalling. Lymphotoxin-β receptor blocking agents are useful for treating lymphocyte-mediated immunological diseases, and more particularly, for inhibiting Th1 cell-mediated immune responses. This invention relates to soluble forms of the lymphotoxin-β receptor extracellular domain that act as lymphotoxin-β receptor blocking agents. This invention also relates to the use of antibodies directed against either the lymphotoxin-β receptor or its ligand, surface lymphotoxin, that act as lymphotoxin-β receptor blocking agents. A novel screening method for selecting soluble receptors, antibodies and other agents that block LT-β receptor signalling is provided.
摘要:
The present invention provides novel ion channel polypeptides and polynucleotides that identify and encode them. In addition, the invention provides expression vectors, host cells and methods for their production. The invention also provides methods for the identification of ion channel agonists/antagonists, useful for the treatment of human diseases and conditions.
