Combinatorial Screening of Biscarbamate Ionizable Lipids Identifies a Low Reactogenicity Lipid for Lipid Nanoparticle mRNA Delivery

Advanced Functional Materials
AbstractMessenger RNA (mRNA) has emerged as a promising therapeutic modality for various diseases. However, efficient delivery of mRNA into target cells remains a significant challenge. In this study, the combinatorial synthesis and characterization of a novel series of ionizable biscarbamate lipids (IBLs) for mRNA lipid nanoparticle (LNP) delivery are

Radiotherapy Enhancement by Gold Nanocluster‐functionalized Nanoliposomes Using Polychromatic Orthovoltage X‐ray Irradiation

Advanced Materials Interfaces, EarlyView.
Lipid drug carriers to which ultra‐small gold nanoparticles were added enabled more efficient radiotherapy of cultured pancreatic cancer tumors. These nanoparticles boosted radiation‐induced damage to tumors by generating more reactive molecules, though higher gold levels are needed for strong benefits.

Disengaging the Engine: Histone Deacetylases 1 and 2‐Mediated Acetylation of Hexokinase‐2 Regulates Energy Metabolism in Microglia Following Intracerebral Hemorrhage

Advanced Science, EarlyView.
This study demonstrates that HDAC1/2 knockout in microglia alleviates neurological deficits, preserves white matter, and accelerates hematoma clearance after ICH. HDAC1/2 inhibition reduces HK2 acetylation, shifts metabolism from glycolysis to fatty acid oxidation, reduces inflammation, and enhances phagocytosis.

Linkage between endosomal escape of LNP-mRNA and loading into EVs for transport to other cells

Nature Communications, 2019
Lipid nanoparticles (LNPs) are potential platforms for RNA-based therapeutics, but the fate of LNP-RNAs upon internalization into the cell is unclear. Here, the authors show that LNP-mRNAs and ionizable lipids escape the endosomes and are re-released via

Dynamics of the Mammalian Placental Metabolome in Placentogenesis and Embryonic Development

Advanced Science, EarlyView.
This study identifies three metabolic stages (E8.5, E9.5–10.5, E11.5–14.5) and two transition periods (E8.5–9.5, E10.5–11.5) in mouse placental development. NAD(H) emerges as a key dynamic metabolite that enhances embryonic growth through accelerated segmentation and increased proliferation of mouse embryonic stem cell (mESC)‐induced presomitic ...

Mitochondria-targeted gene delivery using fluorinated lipid nanoparticles to alleviate Leber’s hereditary optic neuropathy

Nature Communications
Mutations in mitochondrial DNA (mtDNA) lead to various mitochondrial diseases for which no cure is currently available. Despite the promising potential of mtDNA correction to treat these disorders, the double mitochondrial membranes have proven to be a ...

Regulating Tumor Metabolic Reprogramming with Biomimetic Co‐Delivery of Simvastatin and Kynureninase for Immunotherapy

Advanced Science, EarlyView.
After the intravenous injection of biomimetic and pH/ROS‐responsive PTSK@CRM, the nanoparticles can be accumulated in tumors and release Sim and KYNase to inhibit the tumor growth, regulate the metabolism of cholesterol and Kyn, and reverse the immunosuppressive tumor microenvironment.

Spotlighting the criticality of lipid quality control through a mechanistic investigation of mRNA activity loss in lipid nanoparticles

Communications Chemistry
Lipid nanoparticles (LNPs) have gained much attention after the recent launch of mRNA based Covid vaccines. For mRNA encapsulated within LNPs to be successfully translated into target proteins, the mRNA must maintain its integrity and also be free of any

Testicular mRNA‐LNP Delivery: A Novel Therapy for Genetic Spermatogenic Disorders

Advanced Science, EarlyView.
In the current study, we developed a novel therapy for genetic spermatogenic disorders. It was revealed that in vivo delivery of mRNA LNP3 could restore spermatogenesis in Msh5D486Y/D486Y and Maps KO mouse models with meiotic arrest. Notably, the offspring without genomic integration was born using ICSI derived from the rescue of Msh5D486Y/D486Y mouse ...
