TL;DR: In this article, chemically modified short interfering RNAs (siRNAs) were used to silence an endogenous gene encoding apolipoprotein B (apoB) after intravenous injection in mice.

TL;DR: The best-performing lipid recovered after screening (DLin-KC2-DMA) was formulated and characterized in SNALP and demonstrated to have in vivo activity at siRNA doses as low as 0.01 mg/kg in rodents and 0.1 mg/ kg in nonhuman primates, a substantial improvement over previous reports of in vivo endogenous hepatic gene silencing.

TL;DR: It is shown that siRNAs, when delivered systemically in a liposomal formulation, can silence the disease target apolipoprotein B in non-human primates, supporting RNAi therapeutics as a potential new class of drugs.

TL;DR: It is estimated that escape of siRNAs from endosomes into the cytosol occurs at low efficiency (1–2%) and only during a limited window of time when the LNPs reside in a specific compartment sharing early and late endosomal characteristics.

TL;DR: A targeting approach using an exogenous ligand containing a multivalent N-acetylgalactosamine (GalNAc)-cluster, which binds with high affinity to the asialoglycoprotein receptor (ASGPR) expressed on hepatocytes appears to be highly effective for the delivery of iLNPs to liver.
