RNA modified immune therapies

Our lab focuses on applying the latest state-of-the-art in oligonucleotides for immune diseases and immune cell modification. We are embedded in the clinical department of hematology/oncology and are set out the realize the rapid bed-to-bedside potential of RNA based therapies. We are currently focusing on optimizing oligonucleotide uptake and duration of effect in essential cell based therapies, such as in stem cell transplantation, donor lymphocyte infusion, CAR T cell etc.


GRT projects

Precise immunosuppression for GvHD prophylaxis and/or treatment

  • RNA modified donor lymphocyte infusions
  • RNA modified hematopoetic stem cell grafts
  • Systemic treatment of HSCT mice (and patients) with RNA therapeutics

Aicardi Goutieres Syndrome

  • LINE1 downregulation

Duration of effect of RNA therapeutics in rapidly dividing cells


GRT expertise

  • siRNA, artificial miRNA, antimir, LNPs, extracellular vesicles, oligonucleotide pharmacokinetics
  • RNA modified cell therapies
  • hematopoetic stem cell transplantation, graft-versus-host disease
  • Main GRT methods applied in the lab
