Abstract
Provided herein are reporter T-cells containing a reporter operably linked to the Nur77 locus. Also provided are methods for screening for an activity of a recombinant receptor, including those containing an extracellular antigen-binding domain and an intracellular signaling domain, such as a chimeric antigen receptor (CAR), including assessing activity of a cell expressing the recombinant receptor based on a detectable expression of a reporter molecule responsive to a signal through the intracellular signaling region of the recombinant receptor. In some embodiments, the activity assessed is an antigen-dependent or an antigen-independent activity. In some embodiments, the methods can be used to screen a plurality of reporter cells each containing a nucleic acid molecule encoding a candidate recombinant receptor, e.g. CAR, and assessing such cells for one or more property or activity. The methods can be high-throughput. Also provided are reporter cells, cell compositions, nucleic acids and kits for use in the methods.
