Low immunogenicity of LNP allows repeated administrations of CRISPR-Cas9 mRNA into skeletal muscle in mice

Abstract

In vivo delivery of CRISPR-Cas9 holds promise for treating muscular dystrophy, however, AAV delivery is known to be immunogenic. Here, the authors show that LNP delivery of CRISPR-Cas9 enables repeated injections into skeletal muscle and leads to restored dystrophin expression in multiple muscle groups.
