Schema of nanoparticle fabrication to knockdown Kv1.3 channels (Hajdu et al., 2013)
One of our laboratory research interest is to develop nanoparticles for target delivery of siRNAs to specific T cell subsets. We have fabricated lipid nanoparticles to knock-down Kv1.3 channels in memory T lymphocytes to be used as novel immunosuppressive
agents with limited side effects. These highly versatile scaffoldings can be tailored to individual patient needs for personalized medicine. We have shown their efficacy in vitro and we are now studying their efficacy in vivo in
humanized mouse models of SLE. Further nanoparticles are currently been developed as novel targeted immunotherapies in cancer.
