Fig. 1: The molecular design, expression, and cellular characterization of our antibody-TCR.

From: A novel antibody-TCR (AbTCR) platform combines Fab-based antigen recognition with gamma/delta-TCR signaling to facilitate T-cell cytotoxicity with low cytokine release

a Schematic of our antibody-TCR (AbTCR) platform compared to a TCR and a second-generation CAR platform. b ET190L1-AbTCR is expressed on the surface of primary T cells following lentiviral transduction. Anti-human Fab antibody was used to detect AbTCR expression. Representative flow cytometry plots and images (40×) of T cells stained with anti-human Fab antibody are shown. c AbTCR expression stabilizes the cell surface presentation of CD3ɛ on TCRβ negative J.RT3-T3.5 cells. d The CD3 complex co-immunoprecipitates with the AbTCR. Cell lysates and anti-FLAG immunoprecipitates from primary T cells expressing a FLAG-tagged ET190L1-AbTCR (or untransduced; Mock) were subjected to western blot analysis for CD3δ, ε, γ, and ζ chains
