Journal ArticleDOI

Directional cell movement through tissues is controlled by exosome secretion

TL;DR: In this paper, the authors used intravital imaging to demonstrate that secretion of exosomes from late endosomes is required for directionally persistent and efficient in vivo movement of cancer cells.
Journal ArticleDOI

Optimization of Lipid Nanoparticles for Intramuscular Administration of mRNA Vaccines

TL;DR: Screening a panel of proprietary biodegradable ionizable lipids for both expression and immunogenicity in a rodent model shows that mRNA vaccine tolerability can be improved without affecting potency.
Journal ArticleDOI

A Novel Amino Lipid Series for mRNA Delivery: Improved Endosomal Escape and Sustained Pharmacology and Safety in Non-human Primates

TL;DR: Clear structure-activity relationships were developed that resulted in a new amino lipid that affords efficient mRNA delivery in rodent and primate models with optimal pharmacokinetics and is the first example of the ability to safely repeat dose mRNA-containing lipid nanoparticles in non-human primate at therapeutically relevant levels.
Journal ArticleDOI

Naturally-occurring cholesterol analogues in lipid nanoparticles induce polymorphic shape and enhance intracellular delivery of mRNA.

TL;DR: Structure-activity analysis of cholesterol analogues reveals that incorporation of C-24 alkyl phytosterols into LNPs (eLNPs) enhances gene transfection and the length ofAlkyl tail, flexibility of sterol ring and polarity due to -OH group is required to maintain high transfections.
Journal ArticleDOI

Transventricular delivery of Sonic hedgehog is essential to cerebellar ventricular zone development.

TL;DR: It is demonstrated that the cerebellum is not the source of Shh that signals to the early VZ, and a transventricular path for Shh ligand delivery is suggested, underscoring the potential contribution of VZ progenitors in the pathogenesis of cerebellar diseases associated with deregulated Shh signaling.
