Immunological detection of altered cells
Abstract
Disclosed are methods, compositions of matter, and protocols useful for the detection of altered cells in a patient. Immune cells capable of clonal expansion are engineered to produce a soluble signal upon activation and/or clonal expansion. The cells may possess a suicide gene, inducible upon administration pharmacological or light/radiation activatable, so as to eliminate the cells from body when desired. In another embodiment, immune cells produce a localized marker, the marker being visible with imaging technology. In other embodiments cells capable of non-clonal expansion are utilized. The disclosure provides means of utilizing the immunosurveillance properties of immune cells to diagnose and localize diseases associated with alteration of host cells.
