Despite the success of chimeric antigen receptor (CAR)-T cell therapies in hematological malignancies, clinical success against solid tumors is limited due to low therapeutic efficacy or dose-limiting toxicity. Developing therapies that trigger potent, yet manageable, immune responses capable of eliminating highly heterogeneous and immunosuppressive tumor cell populations remains a key challenge. Here, we harness multiple genetic approaches to develop a CAR-T cell therapy targeting tumors.

We have previously developed a PC-CAR targeting a neuroblastoma-associated PHOX2B peptide, leading to robust tumor cell lysis restricted by two common HLA allotypes. Here, we determine the 2.

To circumvent this limitation, we developed a novel cytoplasmic display platform, Retained Display (ReD), and used it to screen for human scFv frameworks that are highly soluble and stable in the bacterial cytoplasm. ReD, based on the retention of high-molecular weight complexes within detergent-permeabilized Escherichia coli, enabled presentation of exogenous targets to antibodies that were expressed and folded in the cytoplasm.

During meiosis, cohesin is required for the establishment and maintenance of sister-chromatid cohesion, for the formation of the synaptonemal complex, and for recombination between homologous chromosomes. We show that REC8 has an essential role in mammalian meiosis, in that Rec8 null mice of both sexes have germ cell failure and are sterile.
