A brain-sparing diphtheria toxin for chemical genetic ablation of peripheral cell lineages
Abstract
Diphtheria toxin selectively kills cells engineered to express the diphtheria toxin receptor (DTR). Here the authors report a PEGylated version of diphtheria toxin that does not enter the brain, allowing for ablation of only peripheral cells when using Cre lines that drive DTR expression in both the periphery and in the brain.
