摘要: CD8+ T cells recognize and eliminate tumors in an antigen-specific manner. Despite progress characterizing the antitumor cell repertoire function, identification of target antigens remains a challenge. Here we describe use chimeric receptors called signaling antigen-presenting bifunctional (SABRs) cell-based platform for receptor (TCR) antigen discovery. SABRs present extracellular complex comprising peptide major histocompatibility (MHC), induce intracellular via TCR-like signal after binding with cognate TCR. We devised strategy discovery using SABR libraries to screen thousands antigenic epitopes. validated this by identifying targets recognized public TCRs known specificities. Moreover, extended approach personalized neoantigen
