mRNA-based gene editing therapeutics offer the potential to permanently cure diseases but are hindered by suboptimal delivery platforms. Here, we devise a robust combinatorial chemistry for plug-and-play assembly of diverse biodegradable ionizable lipids and identify a lead candidate that produces superior lipid nanoparticles for various gene editing tools delivery . Our study highlights the utility of this synthetic approach and the generality of this platform for potent gene editing.

Base editing, a CRISPR-based genome editing technology, enables precise correction of single-nucleotide variants, promising resolutive treatment for monogenic genetic disorders like recessive dystrophic epidermolysis bullosa (RDEB). However, the application of base editors in cell manufacturing is hindered by inconsistent efficiency and high costs, contributed by suboptimal delivery methods. Nanoneedles have emerged as an effective delivery approach, enabling highly efficient, non-perturbing gene therapies both in vitro and in vivo.

A20/Tnfaip3, an early NF-κB response gene and key negative regulator of NF-κB signaling, suppresses proinflammatory responses. Its ubiquitinase and deubiquitinase activities mediate proteasomal degradation within the NF-κB pathway. This study investigated the involvement of A20 signaling alterations in podocytes in the development of kidney injury.

mRNA-based therapies have broad applications in various disease treatments and have been applied in protein replacement therapy, gene editing, and vaccine development. Numerous research studies have been carried out aiming to increase the stability of mRNA, improve its translational efficiency, and reduce its immunogenicity. However, given mRNA's large molecular size and strong electronegativity, the safety and efficient delivery of mRNA into the target cells remains the critical rate-limiting step in current mRNA drug development.

Wheat is cultivated across diverse global environments, and its productivity is significantly impacted by various biotic stresses, most importantly but not limited to rust diseases, Fusarium head blight, wheat blast, and powdery mildew. The genetic diversity of modern cultivars has been eroded by domestication and selection, increasing their vulnerability to biotic stress due to uniformity. The rapid spread of new highly virulent and aggressive pathogen strains has exacerbated this situation.
