Design and characterization of Axl synNotch in human Jurkat T cells. (A) Axl synNotch design. TF, transcriptional factor (tTA); TFBD, transcriptional factor binding domain. (B) The expression level of the Axl synNotch in Jurkat T cells. The myc-tag was stained with an anti-myc antibody for the measurement of surface synNotch expression. Control indicates non-transfected Jurkat cells that containing only tTA responsive reporter. (C) Axl synNotch response from plate bound Axl protein activation. Control indicates Jurkat T cells harboring synNotch responsible BFP reporter without Axl synNotch. (D) Axl synNotch activation via co-culturing of Axl+/Axl− K562 target cells. (E) BFP fluorescence level after co-culturing of Axl synNotch expressing Jurkat T cells with target K562 cells for 24 hr. Control indicates Jurkat T cells harboring only BFP reporter without Axl synNotch receptor. (F) IL-10 production level when co-cultured Jurkat T cells harboring tTA responsive IL-10 reporter cells with K562 cells for 24 hr. (None, no target cell or no effector cell condition. N.D., not detected: Data are representative of three biological replicates and presented as the mean ± SD).
