- • On November 20, 2017, Cellectis announced the
publication of a study in Molecular Therapy — Nucleic Acids describing the educated engineering of highly specific and efficient TAL nucleases (TALEN®) targeting PD1, a key T-cell immune checkpoint. In this report, Anne-Sophie Gautron, Ph.D., Alexandre Juillerat, Ph.D., and their collaborators used a strategy developed by Cellectis to control TALEN® targeting based on a proprietary technology leveraging the exclusion capacities of non-conventional
RVDs. This approach allows combined disruptions of the desired TRAC and PDCD1 loci by TALEN® while eliminating low frequency off-site processing. By adjusting a few RVDs, they provided a rapid and straightforward redesign of optimal TALEN® combinations for multiplex gene editing. This approach can greatly benefit gene editing for therapeutic applications where high editing efficiencies need to be associated with maximal specificity and safety.
