Atherosclerotic vulnerable plaques pose a risk for acute coronary syndrome and sudden cardiac death due to plaque rupture and thrombosis. While nanomedicines modulating macrophage functions have attracted intensive interest, efficient delivery to plaque macrophages remains challenging. Here, mannose-modified lipid…

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…

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…

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…

Cancer immunotherapy needs potent, pharmaceutically defined, GMP-compatible adjuvants for clinical translation. Poly(I:C) is a widely used TLR3 agonist but has ill-defined structure, heterogeneity, pyrogen contamination, and toxicity concerns. Riboxxim is a well-defined 100-bp double-stranded RNA with a…

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…

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…

In vivo engineering of T lymphocytes is limited by poor transfection efficiency and reliance on ex vivo electroporation. A non-viral mRNA delivery platform that can target primary T cells in vivo is needed for CAR T-cell therapy, vaccines, and immunotherapy. Rough screening identified imidazole head 93 with O17O…

Tumour-associated macrophages (TAMs) are largely M2-like and promote tumour growth, angiogenesis, metastasis, and immune suppression. There is a need for systemic delivery systems that can target TAMs and manipulate their pro-tumour functions with siRNA for cancer immunotherapy. Optimised CL4H6-LNPs had 90% siRNA…

Previous red blood cell (RBC) membrane-coated nanoparticles have all been spherical, missing the physical shape component of biomimicry. Particle shape is a critical design parameter affecting biodistribution, macrophage evasion, and targeted interactions. A platform combining physical biomimicry (anisotropic shape)…

DNA vaccines require high doses because naked DNA is poorly delivered to antigen-presenting cells (APCs), and conventional PLGA microsphere encapsulation by W/O/W emulsion can damage DNA, lower supercoiled DNA content, and give low encapsulation efficiency. A controlled-release system is needed that protects DNA…

Liposome clinical translation is limited by opsonisation and rapid clearance by immune cells. Although the protein corona is recognised as the liposome’s “biological identity,” it was unclear whether pre-adsorbed corona proteins could help liposomes avoid capture by circulating leukocytes in whole blood and thereby…

Many anticancer small molecules have poor aqueous solubility, and verteporfin (VP) has mainly been used as a photodynamic therapy agent, which carries photosensitivity and delivery limitations. PBAE-based materials have been developed extensively for nucleic acid delivery but are less explored for non-genetic…

Dendritic cell (DC)-based immunotherapy requires efficient antigen delivery into DCs, DC maturation, and migration to draining lymph nodes, but real-time tracking of DC migration remains challenging with traditional methods (e.g., FITC painting). While upconversion nanoparticles (UCNPs) offer advantages for sensitive…

Current leishmaniasis chemotherapy lacks options that combine high activity, low toxicity, and affordable cost. Oryzalin (ORZ), a dinitroaniline with in vitro antileishmanial activity, is limited by poor water solubility and low accumulation in diseased organs. Lipid-based nanocarriers may overcome these limitations…

DNA vaccines can induce antibody and CTL responses, but clinical translation is limited by weak potency and the need for high or repeated doses. The study addresses this by targeting DNA to antigen-presenting cells (APCs) and improving endosomal/lysosomal release, using mannose-bearing chitosan microspheres loaded…

Naked plasmid DNA vaccination is largely limited to intramuscular, cutaneous, and intradermal routes because naked DNA is ineffective at crossing mucosal barriers and is rapidly degraded by nucleases. Delivery systems that protect plasmid DNA and target it to antigen-presenting cells are needed for mucosal DNA…

Acetalated dextran (Ac-DEX) is a pH-sensitive, biodegradable polymer useful for drug delivery, but it degrades to methanol, which can be toxic at high concentrations or with repeated dosing. A safer analog that degrades to ethanol instead of methanol is needed for high-volume clinical applications such as multiple…

Conventional adjuvants such as aluminium and Freund’s adjuvants have limitations, including poor cell-mediated immunity and local toxicity. Ginseng stem-leaf saponins (GSLS) have immunomodulatory/adjuvant activity, but improved delivery systems are needed. Cubosomes are stable lipid cubic liquid crystalline…
