摘要:
The present invention relates to novel complexes of major histocompatibility complex (MHC) molecules and uses of such complexes. In one aspect, the invention relates to loaded MHC complexes that include at least one MHC molecule with a peptide-binding groove and a presenting peptide non-covalently linked to the MHC protein. In another aspect, the invention features single chain MHC class II peptide fusion complexes with a presenting peptide covalently linked to the peptide binding grove of the complex. MHC complexes of the invention are useful for a variety of application including: 1) in vitro screens for identification and isolation of peptides that modulate activity of selected T cells, including peptides that are T cell receptor antagonists and partial agonists, and 2) methods for suppressing or inducing an immune response in a mammal.

摘要:
The invention relates to transgenic non-human animals capable of producing heterologous T-cell receptors and transgenic non-human animals having inactivated endogenous T-cell receptor genes. The invention also relates to methods and vectors and transgenes for making such transgenic non-human animals.
摘要:
The present invention features fully soluble and functional single-chain T-cell receptor proteins. In one aspect, the invention features soluble fusion proteins comprising an immunoglobin light chain constant region or fragment thereof covalently linked to a single-chain T-cell receptor, wherein the single-chain T-cell receptor comprises a V-α chain covalently linked to a V-β chain by a peptide linker sequence. The single-chain T-cell receptor proteins have a variety of uses including use in screens to detect cells expressly desired MHC-peptide complexes.
摘要:
Featured is T cell receptor complexes designed to redirect the immune system against various diseases. The T cell receptor complexes of the invention have been engineered to recognize target antigen in a functionally bispecific nature. Fusion protein complexes and protein conjugate complexes are comprised of high affinity antigen-specific TCR and biologically active proteins and/or effector molecules. Also featured are methods of production of T cell receptor fusion and conjugate complexes as well as therapeutic compositions for use of the complexes.
