摘要:
This invention relates to retroviral vectors that express multiple polypeptide subunits of a eukaryotic protein from a single polycistronic mRNA and the proteins produced from these vectors. The expressed proteins are particularly useful for inducing transplantation tolerance and the vectors are useful as agents for mediating gene transfer into eukaryotic cells.
摘要:
Disclosed is a method of directing a cellular response in a mammal by expressing in a cell of the mammal a chimeric receptor which causes the cells to specifically recognize and destroy an infective agent, a cell infected with an infective agent, a tumor or cancerous cell, or an autoimmune-generated cell. Also disclosed are cells which express the chimeric receptors and DNA encoding the chimeric receptors.
摘要:
Disclosed herein are nucleic acid sequences which support episomal replication in a mammalian cell. These nucleic acid sequences, which have a length of less than 3 kb, include (a) an OriP sequence and (b) an EBNA1 sequence operably linked to a promoter.
摘要:
The invention features a synthetic gene encoding a protein normally expressed in a mammalian cell wherein at least one non-preferred or less preferred codon in the natural gene encoding the protein has been replaced by a preferred codon encoding the same amino acid.
摘要:
Fusion proteins are obtained in high yields if a mixed oligonucleotide is constructed which codes for the ballast constituent of the fusion protein. The oligonucleotide mixture is introduced in a vector in such a manner that it is functionally linked to a regulatory region and to the structural gene for the desired protein. Appropriate host cells are transformed with the plasmid population obtained in this manner and the clones producing a high yield of coded fusion protein are selected.
摘要:
Disclosed is a protein, designated RIP, which contains a death domain at its carboxy terminus and a kinase domain at its amino terminus. RIP interacts with the Fas/APO-1 intracellular domain and the TNFR1 intracellular domain. When expressed in transformed host cells, recombinant RIP promotes apoptosis. Also disclosed are DNA molecules encoding RIP, anti-RIP antibodies, and screening methods for discovering inhibitors of RIP-dependent apoptosis.
摘要:
Disclosed herein are organic molecules to which are covalently bonded a sialyl-Lex determinant and a sulfated determinant, at least one of these determinants being positioned at a non-naturally occurring site on the molecule. Also disclosed are particular P-selectin ligands and P-selectin ligand-antibody fusions. These moecules, ligands, and fusion proteins find use in methods of reducing or protecting against inflammation and extravasation-dependent adverse reactions, such as organ damage and clotting (for example, associated with adult respiratory distress syndrome or ischemic myocardial injury).
摘要:
On obtient des hauts rendements de protéines de fusion en construisant un oligonucléotide mélangé qui code pour le constituant de ballast de ladite protéine de fusion. On introduit le mélange oligonucléotide dans un vecteur de telle manière qu'il est lié fonctionnellement à une zone de régulation ainsi qu'au gène de structure pour la protéine desirée. Des cellules hôtes convenables sont transformées avec la population plasmide ainsi obtenue, les clones donnant un haut rendement de protéine de fusion codée étant sélectionnés.
