One of the fundamental weaknesses in cancer treatment or any therapy based at the cellular level is entering the cell. Help us explore a novel method of targeted cell delivery using a mechanism used by clostridium to enter cells. We would like to run a study in which we use recombinant proteins from clostridium and test their effectivity in entering cells. We plan to use this drug delivery system to deliver a CRISPR/Cas9-based nanotherapeutic, already created by our team, into live cells.
