    摘要: Particular interest has arisen regarding the therapeutic potential of regulatory T cells (Tregs) in ischemic stroke. However, the ex vivo-expansion of Tregs usually takes several weeks to achieve a target number of cells. Allogeneic (off-the-shelf) Tregs would be desirable, but are limited by acute graft-versus-host disease (GVHD). As disclosed herein, CD83 is differentially expressed on alloreactive T cells. Therefore, disclosed herein are immune effector cells genetically modified to express a chimeric antigen receptor (CAR) polypeptide targeting CD83 that are capable of suppressing this alloreactivity. In some embodiments, the immune effector cell is used in combination with an autologous Treg therapy. In other embodiments, the autologous Treg is itself genetically modified to express the CAR polypeptide targeting CD83.

    摘要: The present disclosure is directed to methods and compositions for producing a recombinant cell expressing a T cell receptor (TCR) specific for a peptide of interest, methods and compositions for obtaining a nucleic acid or pair of TCR chain polypeptides and/or nucleic acids encoding a TCR, a cell population comprising the recombinant cell harboring the one or more nucleic acids encoding a TCR or TCR chain obtained by said method, and a method for treating a disorder of the central nervous system comprising administering to the subject said cell population.
