Tumor Necrosis Factor-Related Apoptosis-Inducing Ligand (TRAIL) has long been identified as a promising therapeutic due to its ability to induce apoptosis selectively in cancer cells. However, poor stability and rapid clearance of the administered TRAIL protein in circulation have hampered its clinical development…

Hepatocellular carcinoma (HCC) has limited treatment options, with modest survival after systemic chemotherapy or transarterial chemoembolization (TACE). Gene therapies hold promise for treating HCC, but delivery remains a critical hurdle. While poly(beta-amino ester) (PBAE) nanoparticles have shown efficacy in…

Bispecific T-cell engagers (BiTEs) are promising but require large amounts of purified protein, have high manufacturing costs, poor in vivo stability, and short serum half-lives. mRNA delivery could enable continuous endogenous production of BiTEs, but efficient and safe delivery systems are needed. The study…

Liver fibrosis has no approved antifibrotic therapies. Activated hepatic stellate cells (HSCs) drive fibrosis by producing collagen, and HSP47 is a key collagen chaperone in these cells. Targeted delivery of siRNA to activated HSCs remains challenging, so a ligand-tethered LNP platform was developed to deliver RNA…

Fibrosis affects millions of people with cardiac disease and contributes to heart failure. While adoptive transfer of CAR T cells targeting fibroblast activation protein (FAP) has shown promise in reducing cardiac fibrosis, conventional CAR T cells persist for months to years and could cause chronic off-target…

LNPs enabled the COVID-19 mRNA vaccines and the first siRNA-LNP drug, but there is still no one-size-fits-all LNP for every RNA therapeutic. A better chemistry-level understanding of LNP self-assembly, component roles, and whole-particle properties is needed to rationally design safer and more efficient RNA delivery…

Lipid-conjugated siRNAs can reach extrahepatic tissues, but silencing efficacy remains lower than in liver largely because only ~1–2% of internalised siRNA escapes endosomes into the cytoplasm. Ionisable lipids enhance endosomal escape in lipid nanoparticles (LNPs), but direct covalent conjugation of an ionisable…

mRNA delivery to T cells could enable ex vivo and in vivo T cell engineering, but LNPs still face poor extrahepatic delivery, endosomal recycling, and limited T cell transfection. Cholesterol analogs such as hydroxycholesterols may alter NPC1 recognition and endosomal trafficking, providing a route to improve T cell…

Ex vivo T-cell engineering is effective but complex, costly, and difficult to scale. A method to transfect T cells directly in situ could simplify T-cell immunotherapy, but T-cell targeting may also trigger activation, depletion, cytokine release, and phenotypic changes that must be understood. In vitro: 80% of…

Cardiomyocytes are hard-to-transfect cells, and gene therapy for cardiovascular disease is limited by insufficient delivery to cardiac tissue, nucleic acid degradation, and safety concerns with viral vectors. A safe, effective non-viral platform for pDNA delivery to cardiomyocytes is needed. LNP4 was the top…

LNPs can trigger innate immune responses and inflammation, which can suppress mRNA translation and cause adverse effects. There is a need for LNP formulations that reduce LNP-induced inflammation while maintaining or improving mRNA delivery. C9D1 and C10D0 had similar size, PDI, and 90% mRNA encapsulation; Dex…

Systemic LNP delivery predominantly targets the liver, while extrahepatic delivery—especially to lung airway epithelium for diseases such as cystic fibrosis—remains challenging. DOTAP is a common cationic lipid for lung gene delivery but is racemic, pseudo-glyceryl, and slowly biodegradable. Novel readily…

Polymeric gene delivery vectors require detailed physicochemical characterisation to ensure reproducible formulation and efficient transfection. PBAE-447 is a promising biodegradable cationic polymer, but its simple nanoparticles can degrade or aggregate in aqueous/physiological conditions. This study characterises…

Four-component lipid nanoparticles (LNPs) represent the leading non-viral vectors for mRNA delivery, but they have limitations including: (1) segregation of the neutral ionisable lipid as droplets in the LNP core, reducing transfection efficiency to ~1-2%; (2) the "PEG dilemma" where PEGylation increases circulation…

T cells are notoriously resistant to exogenous mRNA transfection, limiting in vivo T cell engineering for immunotherapy, CAR T generation, and HIV cure. A safe, specific, and efficient in vivo mRNA delivery platform for CD4+ T cells was needed. In vitro: anti-CD4/mRNA-LNPs bound specifically to human CD4+ T cells…

Retroviral gene delivery for T cell therapies is expensive, semi-randomly integrating, and variable between patients. Non-viral alternatives are needed, but T cells are notoriously hard to transfect, especially primary T cells. Lipofectamine LTX was the best vehicle in Jurkat cells; optimised conditions in X-VIVO…

CRISPR/Cas gene-editing components are often encoded on large plasmids (9–19 kb), which are difficult to encapsulate and transfect. Most PLGA nanoparticle (NP) gene-delivery studies use small nucleic acids (siRNA) or small plasmids (<6 kb), and the structural integrity and functional performance of large plasmids in…

Gene-editing tools are large plasmid constructs that cannot spontaneously enter mammalian cells, and viral vectors are limited by cargo size, immunogenicity, and manufacturing challenges. PBAE nanoparticles are promising nonviral carriers, but unmodified PEG-PDHA nanoparticles release encapsulated plasmid DNA too…

Non-viral vectors such as nanoparticles (NPs) show promise for RNA-based therapies, but suffer from limited cell targeting, poor cellular internalisation, and inadequate endolysosomal escape capacity. The field lacks a systematic, high-throughput approach to identify effective polymeric nanocarriers that can deliver…

Bispecific T-cell engager (BiTE) immunotherapy is a promising cancer treatment, but clinical application is limited by high production costs and short in vivo half-life of BiTE proteins. A gene delivery system that enables sustained in vivo expression of BiTE could overcome these limitations, but existing non-viral…

Exosomes are nanosized membranous vesicles with unique properties (abundant membrane proteins, high biocompatibility, low immunogenicity) that make them attractive for therapeutic development. While exosomes have been studied as drug delivery vehicles, fewer studies have focused on engineering exosome surface…

Monoclonal antibody anti-tumour therapies rely on NK cell-mediated antibody-dependent cell-mediated cytotoxicity (ADCC), but patient responses vary widely. While tumour antigen escape is one cause of treatment failure, the role of inter-individual variation in NK cell serial killing capacity—the ability of a single…
