Redirected, genetically-engineered t regulatory cells and their use in suppression of autoimmune and inflammatory disease
InactiveUS20100135974A1Effective quantityOvercome scarcityBiocideAntipyreticIntracellular signallingInflammatory Bowel Diseases
A redirected Treg cell is endowed with specificity toward a selected target antigen or ligand. The cell contains a chimeric receptor polypeptide that is expressed in a single, continuous chain, with an extracellular recognition region displayed on the surface of the cell, a transmembrane region and an intracellular signaling region. The extracellular recognition region is specific for the selected target antigen or ligand. The intracellular signaling region includes a combination of T-cell signaling polypeptide moieties, which combination, upon binding of the extracellular recognition region to the selected target antigen or ligand, triggers activation of the redirected Treg cells to cause suppression of T-cell mediated immunity. Such redirected Treg cells may be used to suppress undesired activity of T effector cells thereby mediating an immune or inflammatory response. They are particularly useful in treating T effector cell-mediated diseases, such as inflammatory bowel disease, transplant rejection and GVH disease.

Genome-wide analysis of copy number changes in breast and colorectal tumors used approaches that can reliably detect homozygous deletions and amplifications. The number of genes altered by major copy number changes—deletion of all copies or amplification of at least twelve copies per cell—averaged thirteen per tumor. These data were integrated with previous mutation analyses of the Reference Sequence genes in these same tumor types to identify genes and cellular pathways affected by both copy number changes and point alterations. Pathways enriched for genetic alterations include those controlling cell adhesion, intracellular signaling, DNA topological change, and cell cycle control. These analyses provide an integrated view of copy number and sequencing alterations on a genome-wide scale and identify genes and pathways that are useful for cancer diagnosis and therapy.
