Glioblastoma (GBM) remains one of the most aggressive brain malignancies, with limited therapeutic success largely due to the restrictive nature of the Blood-Brain Barrier (BBB) and intrinsic drug resistance mechanisms. Despite standard treatment strategies, the median survival remains approximately 16 months…

LAF-Stp xenopeptides (XPs) comprising lipoamino fatty acid (LAF) units connected with the tetraethylene pentamine derived polyamino acid Stp were identified as a novel class of amphiphilic mRNA carriers. A 'chameleon-like' polarity switch is observed upon transition from neutral physiological to endosomal acidic pH…

Nucleoside-modified mRNA lipid nanoparticle (modmRNA-LNP) technology is clinically successful, but its behaviour in pre-existing inflammatory or immune-challenged conditions is poorly characterised. This gap raises the risk of adverse effects when modmRNA-LNPs are administered to patients with ongoing inflammation…

Congenital protein deficiencies often begin irreversible pathology in utero, but postnatal treatments are limited. In utero mRNA delivery could enable protein replacement before disease onset, yet LNP stability in fetal amniotic fluid and how it affects mRNA delivery had not been previously investigated. LNP A12 was…

Modified mRNA (modRNA) is a promising cardiac regeneration therapeutic, but naked mRNA is large, negatively charged, and rapidly degraded. It is unknown whether systemically administered lipid nanoparticles (LNPs) can functionally deliver mRNA to ischaemic/damaged myocardium after myocardial infarction. LNPs were…

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…

CAR T cell therapy for solid malignancies typically results in poor responses. Systemic administration of immunomodulatory biologics (cytokines, BiTEs) can augment T cell activity but off-target toxicity narrows the therapeutic window. A method to spatially and temporally control transgene expression by engineered T…

T-cell-based immunotherapies such as CAR-T cells and bispecific T-cell engagers (BiTEs) have shown promise but have significant limitations: (1) poor pharmacokinetics requiring continuous infusion (BiTE half-life ~2 h), and (2) single-antigen targeting leading to antigen-loss tumour escape and relapse. A modular…

Glioblastoma (GBM) is one of the deadliest primary adult tumours with a median survival of only 14.6 months post-diagnosis, a statistic that has changed little in two decades. While cancer immunotherapy has shown remarkable progress in other solid tumours, the blood-brain barrier (BBB) and the immune-privileged…

Microfluidic mixing can produce precise LNPs but is limited in throughput, while bulk mixing is scalable but yields larger, heterogeneous particles with variable potency. A scalable microfluidic device is needed to produce potent RNA-LNPs across discovery and clinical scales. PMD achieved 18.4 L/h production…

PLGA microspheres are widely used for controlled drug release, but they often exhibit pronounced initial or mid-term burst release. A strategy is needed to finely tune drug release kinetics and suppress burst release, especially for water-soluble drugs. MSNs: Average size 119 nm; specific surface area 902.53 m²/g…

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…

Regulatory T cell (Treg)-based therapeutics show promise for treating autoimmune diseases and preventing transplant rejection, but adoptive Treg transfer is expensive, complex, and difficult to implement. "Off-the-shelf" non-cellular alternatives that can induce endogenous Tregs in vivo are needed. Existing…

CAR T and TCR T cell therapies are powerful but face prohibitive costs and manufacturing complexity due to the need for leukapheresis, ex vivo transduction, expansion, and quality control—all under GMP conditions. An "off-the-shelf" injectable nanocarrier that can transiently reprogram circulating T cells in vivo…

Macropinocytosis has been shown to regulate the growth of Ras-transformed tumour cells under amino acid (AA)-limiting conditions by providing extracellular proteins that are degraded into AA to fuel cell growth and activate mTORC1. However, whether macropinocytosis regulates the growth of non-transformed mammalian…

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…

T-cell receptor (TCR)-modified T-cell gene therapy can target a variety of extracellular and intracellular tumour-associated antigens, yet has had little clinical success. A potential explanation for limited antitumor efficacy is a lack of T-cell activation in vivo, particularly when tumour cells downregulate…

Ultrasmall silica nanoparticles (USSN, <10 nm diameter) were recently shown to stimulate T lymphocytes directly at relatively low exposure doses, but the underlying mechanisms and associated cell signalling were unknown. Understanding whether USSN directly engage the T cell receptor (TCR) complex or act through other…

Small-sized lipid nanoparticles (LNPs) are attractive for tissue penetration but often lose potency because lipid components diffuse out and serum proteins adsorb onto poorly packed surfaces. The study asked how the hydrophobic scaffold structure of pH-sensitive cationic lipids affects small-LNP stability, lipid…

LNP libraries are usually screened in vitro, which poorly predicts in vivo mRNA delivery. A high-throughput in vivo platform was needed to screen many LNP formulations simultaneously and identify lead carriers for functional mRNA delivery. b-mRNA could be detected in liver at doses as low as 17 ng; b-mRNA delivery…

Folic acid (FA)-mediated active targeting improves nanocarrier tumour specificity but exposes targeting ligands to the immune system, causing rapid clearance and nonspecific uptake. Existing acid-labile benzoic-imine PEG sheddable systems are insufficiently stable at physiological pH. A more stable, tumour-triggered…
