Defining potency of CAR+ T cells: Fast and furious or slow and steady

Blog Article

Genetically engineered T cells that express chimeric antigen receptors (CAR+) are heterogeneous and thus, understanding the immunotherapeutic efficacy remains a challenge in adoptive cell therapy.We developed a high-throughput single-cell click here methodology, Timelapse Imaging Microscopy In Nanowell Grids (TIMING) to monitor interactions between immune cells and tumor cells in vitro.Using TIMING we demonstrated that CD4+ CAR+ T cells participate in multi-killing and benefit from improved resistance stickers logos dallas cowboys to activation induced cell death in comparison to CD8+ CAR+ T cells.

For both subsets of cells, effector cell fate at the single-cell level was dependent on functional activation through multiple tumor cells.
