Stem Cell Related Patent Number US6407221
| Title: | Chimeric chains for receptor-associated signal transduction pathways | | Inventors: | Capon, Daniel J.; Hillsborough, CA, USA | | Summary: | Described herein is a novel chimeric protein with a non-major histocompatability complex, a restricted extracellular binding domain, a transmembrane domain, and a cytoplasmic signal-transducing domain. The invention relates to chimeric proteins and DNA encoding the chimeric proteins, in which the chimeric proteins are characterized by an extracellular domain capable of binding to a ligand in a non-MHC restricted manner. Further disclosed are properties of a transmembrane domain and a cytoplasmic domain capable of activating a signaling pathway. Claims of the invention include the binding of a ligand to the extracellular domain, resulting in the transduction of a signal and the activation of a signaling pathway in the cell, whereby the cell may be induced to carry out various functions relating to the signaling pathway. Therapeutic applications in signal transduction are provided. | | Abstract: | Chimeric proteins and DNA encoding chimeric proteins are provided, where the chimeric proteins are characterized by an extracellular domain capable of binding to a ligand in a non-MHC restricted manner, a transmembrane domain and a cytoplasmic domain capable of activating a signaling pathway. The extracellular domain and cytoplasmic domain are not naturally found together. Binding of ligand to the extracellular domain results in transduction of a signal and activation of a signaling pathway in the cell, whereby the cell may be induced to carry out various functions relating to the signalling pathway. A wide variety of extracellular domains may be employed as receptors, where such domains may be naturally occurring or synthetic. The chimeric DNA may be used to modify lymphocytes as well as hematopoietic stem cells as precursors to a number of important cell types. | | US Patent Website: | Click Here for Full Text of Patent | | Title Number: | US6407221 | | Application Number: | US1995000475442 | | Date Filed: | 07/06/1995 | | Date Published: | 18/06/2002 | | Assignee: | Cell Genesys, Inc., Foster City, CA, USA
