摘要:
The instant invention provides plant expression vectors comprising a first promoter operable in a plant, an expressible nucleic acid sequence encoding a mammalian tissue factor protein or functional fragment thereof, wherein the nucleic acid sequence is peparatively associated with the promoter, and a termination sequence operatively associated with the nucleic acid sequence. The invention further provides methods of making the tissue factor protein, or functional fragment thereof, using the claimed vectors and plants, and methods of treating or preventing blood loss, of promoting wound healing, promoting angiogenesis, or promoting vascular remodeling in a subject by administering the tissue factor proteins to a subject.
摘要:
Disclosed are compositions and methods for detecting cells or tissue comprising a peptide antigen presented in the context of an MHC or HLA complex. The invention has a wide range of applications including providing a highly sensitive method for detecting cancer cells.
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 applications 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 provides soluble fusion protein complexes having at least two soluble fusion proteins. The first fusion protein is a biologically active polypeptide covalently linked to an interleukin-15 (IL-15) polypeptide or a functional fragment thereof. The second fusion protein is a second biologically active polypeptide covalently linked to a soluble interleukin-15 receptor alpha (IL-15Rα) polypeptide or a functional fragment thereof. In the complexes of the invention, one or both of the first and second fusion proteins further includes an immunoglobulin Fc domain or a functional fragment thereof; and the first fusion protein binds to the soluble IL-15Rα domain of the second fusion protein to form a soluble fusion protein complex. The invention further provides methods for making and using the complexes of the invention.

摘要:
The invention provides T-cell receptor (TCR) molecules 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 to 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 applications including therapeutic uses and use in the detection of cells expressing p53 protein.
