摘要: Provided herein are compositions and methods for modifying regulatory T cells. The inventors have identified nuclear factors that influence expression of Foxp3, a key transcriptional regulator of Treg cells. Treg cells can be modified by inhibiting and/or overexpressing one or more of these nuclear factors to produce stabilized Treg cells or destabilized Treg cells.

摘要: Methods are described herein for isolating clonal populations of T cells having a defined genetic modification. The methods are performed, at least in part, in a microfluidic device comprising one or more sequestration pens. The methods include the steps of: maintaining individual T cells (or precursors thereof) that have undergone a genomic editing process in corresponding sequestration pens of a microfluidic device; expanding the T cells into respective clonal populations of T cells; detecting, in one or more T cells of each clonal population, the absence of a cell surface marker that was present in the individual T cells (or precursors thereof); and detecting, in one or more T cells of each clonal population, the presence of a first nucleic acid sequence that is indicative of the presence of an on-target genome edit in the clonal population of T cells. Also described are compositions comprising one or more clonal populations of T cells isolated according to the methods disclosed herein.
