摘要:
This invention relates to the use of monoclonal and polyclonal antibodies that specifically bind to and have the ability in the alternative to become internalized by cells expressing endosialin and to induce an immune effector activity such as antibody-dependent cellular cytotoxicity. The antibodies are useful in specific delivery of pharmacologic agents to endosialin-expressing cells as well as in eliciting an immune-effector activity particularly on tumor and neovascular cells and precursors. The invention is also related to nucleotides encoding the antibodies of the invention, cells expressing the antibodies; methods of detecting cancer and neovascular cells; and methods of treating cancer and neovascular disease using the antibodies, derivatives and fragments.

Monoclonal antibodies and other proteins that specifically bind to cells positive for endosialin are provided. The antibodies and proteins are useful in the isolation of endosialin-positive cells, particularly cells associated with neovascularization associated with cancer and neovascular disease. The invention is also related to cells that are isolated using monoclonal antibodies; antibody derivatives, such as chimeric and humanized monoclonal antibodies; antibody fragments; mammalian cells expressing the monoclonal antibodies, derivatives and fragments; and methods of detecting and isolating endosialin-positive cells using the antibodies, derivatives and fragments.
摘要:
Dominant-negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into mammalian cells new cell lines with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation or introduction of mutations by chemical mutagens. These methods are useful for generating novel and highly active antimicrobial molecules as well as superior antimicrobial agents from pre-existing chemicals. These methods are also useful for generating cell lines expressing novel antimicrobials that are useful for pharmaceutical manufacturing.

Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into cells and transgenic animals, new cell lines and animal varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation. Methods of generating mutations in genes of interest and of making various cells mismatch repair defective through the use of chemicals to block mismatch repair in in vivo are disclosed.

Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into cells and transgenic animals, new cell lines and animal varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation. These methods are useful for generating genetic diversity within immunoglobulin genes directed against an antigen of interest to produce altered antibodies with enhanced biochemical activity. Moreover, these methods are useful for generating antibody-producing cells with increased level of antibody production. The invention also provides methods for increasing the effector function of monoclonal antibodies and monoclonal antibodies with increased effector function.

The invention is also related to nucleotides encoding the antibodies of the invention, cells expressing the antibodies; methods of detecting cancer cells; and methods of treating cancer using the antibodies.
摘要:
Bacteria are manipulated to create desirable output traits using dominant negative alleles of mismatch repair proteins. Enhanced hypermutation is achieved by combination of mismatch repair deficiency and exogenously applied mutagens. Stable bacteria containing desirable output traits are obtained by restoring mismatch repair activity to the bacteria.
摘要:
Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. Cells may be selected for expression of activation-induced cytidine deaminase (AID), stimulated to produce AID, or manipulated to express AID for further enhancement of hypermutability. These methods are useful for generating genetic diversity within immunoglobulin genes directed against an antigen of interest to produce altered antibodies with enhanced biochemical activity. Moreover, these methods are useful for generating antibody-producing cells with increased level of antibody production.
