    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.

    摘要: 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.
