Abstract

Peng et al. report a sensitive method to detect tumor-associated neoantigen-specific T cells. Neoantigens and fluorescent DNA barcodes, presented on nanoparticle scaffolds, permit multiplex capture and analysis of specific T cell populations from blood or tumor. Neoantigen-specific T cell numbers track tumor volume in a melanoma patient responding to immunotherapy.
