    Modular Chimeric Cytokine Receptors with Leucine Zippers Enhance the Antitumour Activity of CAR T Cells via JAK/STAT Signaling

    Investigators showed that replacement of the extracellular domains of heterodimeric cytokine receptors in T cells with two leucine zipper motifs provided optimal Janus kinase (JAK)/signal transducer and activator of transcription (STAT) signaling.
