    摘要: The invention features compositions based on thioredoxin-like fold protein domains described as engineered thioredoxin-like fold proteins (ETRXs). These proteins include one or more artificially diversified thioredoxin-like fold protein domains; each domain may be originated from the same or different thioredoxin-like fold protein domains. Features of the invention also include methods for identifying and preparing an enriched composition of target binding, loop-diversified ETRXs with additional sequence variations to improve affinity, stability, selectivity, or solubility. The invention also features compositions of ETRXs substituted with prosthetic groups, polymers, proteins, nucleic acids, carbohydrates, metals, natural or synthetic small molecules and toxins.

    摘要: Disclosed is a method of directing a cellular immune response against an HIV-infected cell in a mammal involving administering to the mammal an effective amount of therapeutic cells which express a membrane-bound, proteinaceous chimeric receptor comprising (a) an extracellular portion which includes a fragment of CD4 which is capable of specifically recognizing and binding the HIV-infected cell but which does not mediate HIV infection and (b) an intracellular portion which is capable of signalling the therapeutic cell to destroy the receptor-bound HIV-infected cell. Also disclosed are cells which express the chimeric receptors and DNA and vectors encoding the chimeric receptors.

    摘要: A simple and highly efficient method for cloning cDNAs from mammalian expression libraries based on transient expression in mammalian host cells has been discovered. Novel expression vectors allowing highly efficient construction of mammalian cDNA libraries are disclosed. The cloning method of the invention which has been used to clone genes for cell surface antigens of human lymphocytes, has general application in gene cloning. Cell surface antigens cloned according to the present invention have been purified, and the nucleotide and amino acid sequences determined. These antigens have diagnostic and therapeutic utility in immune-mediated infections in mammals, including humans.
