What modifications could Moderna make to its lipid nanoparticle delivery system to increase cellular uptake of mRNA therapeutics?

Introduction

To improve Moderna's lipid nanoparticle (LNP) delivery system for increased cellular uptake of mRNA therapeutics, we need to analyze the current system, identify key challenges, and propose innovative modifications. I'll approach this by examining the LNP components, cellular uptake mechanisms, and potential areas for enhancement.

Clarifying Questions
