Järås' Research Group

 

Gruppbild 191108

To idenify new therapeutic opportunities in cancer, we work on the following projects:

  • In vivo CRISPR-screens using leukemia stem cells.
  • CRISPR screens in leukemia cells co-cultured with NK cells or macrophages.
  • Development of therapeutic antibodies directed to new targets.

Successful completion of these projects will identify new therapeutic targets in acute myleoid leukemia (AML) and expand our knowledge regarding how cancer cells evade the immune system, findings that may translate into new therapeutic opportunities.
