Research Summary

Nicholas  Parrish(M.D., Ph.D)

I am interested in the interactions between an organism’s genome and its viruses, especially how “self,” in the immunological sense, is established at the genome level. As a medical doctor with training in surgery, I am seeking new understanding that could enable practical innovations in preventing and treating virus infections and allowing tolerance to specific “non-self,” for example transplanted organs. My colleagues and I found that viral sequences present in some mammalian genomes can generate small RNAs called piRNAs. My team will test the hypothesis that this enables RNA interference to prevent or ameliorate virus infection.
