Gene Delivery & Gene Editing in the Retina

Synopsis

  • Overview of methods for “in vivo” delivery to retina
  • Genes delivery to different cell types in retina

10.10
Using CRISPR to Modulate Immunosuppressive Pathways in CAR T Cell Products

Synopsis

  • Identified a highly specific gRNA for knockout of the TGFβRII gene in primary CAR T cells using CRISPR
  • Validated that TGFβRII KO mediated CAR T cell products resistant to TGFβ-mediated suppression
  • Identified a TGFβ RNA signature that is induced when CAR T cells see antigen expressing tumor cells in the presence of TGFβ; this signature is reversed when TGFβRII is knocked out by CRISPR
