    摘要: The invention provides T-cell receptor (TCR) molecules comprising a Vα chain and a Vβ chain that bind peptides derived from the p53 protein, preferably, the human p53 protein. The TCR molecules include both heterodimeric molecules and single chain molecules which specifically bind a sequence preferably spanning about amino acid positions 264-272 of the p53 protein displayed in the context of an HLA molecule, preferably, HLA-A2.1. Also disclosed are methods for making and using such TCR molecules. The invention has a wide spectrum of useful application including therapeutic uses and use in the detection of cells expressing p53 protein.

    摘要: The present invention is related to methods of assaying potency of a vaccine composition, wherein the potency is a pre-defined minimum level of potential biological activity for the vaccine composition. The method includes providing a vaccine composition and delivering same to an antigen presenting cell, wherein the vaccine composition is processed into peptides and the peptides are presented by MHC complexes on the cell surface. An agent, such as a T cell receptor mimic, that is reactive against a specific peptide/MHC complex is provided and reacted with the vaccine-treated antigen presenting cell, whereby the agent binds to the cell surface of the vaccine-treated antigen presenting cell if the specific peptide/MHC complex recognized by the agent is present on the cell surface. A density of the specific peptide/MHC complex on the surface of the vaccine-treated antigen presenting cell is measured by agent binding. The potency of the vaccine is then determined based upon the measured density of specific peptide/MHC complex present on the surface of the vaccine-treated antigen presenting cell.

    摘要: The present invention relates to a methodology of producing antibodies that recognize peptides associated with a tumorigenic or disease state, wherein the peptides are displayed in the context of HLA molecules. These antibodies will mimic the specificity of a T cell receptor (TCR) but will have higher binding affinity such that the molecules may be used as therapeutic, diagnostic and research reagents. The method of producing a T-cell receptor mimic of the present invention includes identifying a peptide of interest, wherein the peptide of interest is capable of being presented by an MHC molecule. Then, an immunogen comprising at least one peptide/MHC complex is formed, wherein the peptide of the peptide/MHC complex is the peptide of interest. An effective amount of the immunogen is then administered to a host for eliciting an immune response, and serum collected from the host is assayed to determine if desired antibodies that recognize a three-dimensional presentation of the peptide in the binding groove of the MHC molecule are being produced. The desired antibodies can differentiate the peptide/MHC complex from the MHC molecule alone, the peptide alone, and a complex of MHC and irrelevant peptide. Finally, the desired antibodies are isolated.
