COMPOSITIONS AND METHODS FOR SURROGATE ANTIBODY MODULATION OF AN IMMUNE RESPONSE AND TRANSPORT

摘要

Methods and compositions for the modulation of an immune response are provided. Compositions comprise a bi-functional surrogate antibody molecule that interacts with a ligand of interest, wherein the bi-functional surrogate antibody further has attached thereto an immunomodulatory agent and/or a transporting agent. The compositions of the invention find use in a method for delivering an immunomodulatory agent to a ligand of interest. Further provided are methods for modulating an immune response in a subject against a ligand of interest. The method comprises administering a therapeutically effective amount of a bi-functional surrogate antibody of the invention. The methods of the invention also find use in improving the clinical outcome of a subject in need of a modulation in the immune response. Methods are further provided for the treatment or prevention of a variety of conditions and/or disorders including cancer, autoimmune diseases, allergies, prions, and various diseases or conditions of bacterial, parasitic, yeast or viral etiology.
