Cancer immunotherapy has improved clinical outcomes, but few patients show adequate response rates and long-term responses, and systemic side effects remain common due to the dynamic nature of the immune system. Biomaterial-assisted immunotherapy is a promising approach to improve therapeutic efficacy and reduce side…

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…

CAR T cell therapy currently relies on viral vectors or electroporation for T cell engineering. Viral vectors cause permanent CAR expression and carry safety/manufacturing limitations, while electroporation is cytotoxic and requires specialised equipment. A safer, efficient non-viral mRNA delivery platform for human…

CAR-T cell therapy is limited by complex manufacturing, viral vector use, high cost, and severe toxicities. A nonviral, transient CAR modification approach using self-assembled nanoparticles could provide a simpler, safer, and potentially broadly applicable alternative for T-cell engineering. Formulation screening…

Cancer is a leading cause of mortality worldwide, and conventional treatments and cytotoxic immunotherapies have limitations. Because tumours are complex and involve multiple genetic and cellular factors in tumorigenesis and metastasis, there is a need for an immunotherapy that targets tumours at both cellular and…

Fibrosis is observed in nearly every form of myocardial disease and contributes to heart failure, yet clinical interventions targeting fibrosis remain limited. No therapies directly target excessive cardiac fibrosis, and very few interventions improve cardiac function in patients with impaired compliance. Genetic…

CAR-T cell therapy relies mainly on retroviral/lentiviral vectors, which carry risks of carcinogenicity and complex manufacturing. PiggyBac transposon systems offer a safer, simpler non-viral alternative for stable transgene expression, but primary T lymphocytes are difficult to transfect efficiently. A polymeric…

mRNA-based cancer vaccination is a promising approach for personalised immunotherapy, but safe and effective mRNA delivery remains a major challenge due to mRNA's instability and poor cell membrane permeability. While lipid nanoparticles (LNPs) are the primary delivery strategy, they have limitations with respect to…

Genetic modification of human T lymphocytes is critical for both basic research and emerging therapies (e.g., CAR-T cells), but established non-viral methods are highly inefficient. Linear polyethylenimine (l-PEI), the "gold standard" for non-viral transfection of mammalian cells, achieves only single-digit…

Efficient mRNA delivery to lymphocytes remains a major unmet need for immunotherapy and vaccinology. Current methods rely largely on physical transfection such as electroporation, which is ex vivo, costly, and inefficient; chemical vectors generally achieve low lymphocyte mRNA transfection, especially in vivo. Lead…

CAR T cell immunotherapy requires efficient ex vivo gene delivery to primary human T cells, but viral vectors have limitations including cost, cargo size, insertional mutagenesis risk, and manufacturing complexity. Non-viral cationic polymers are attractive alternatives but historically show low gene transfer…

Cancer stem cells (CSCs) drive tumour heterogeneity, drug resistance, recurrence, and metastasis, limiting conventional chemo/radiotherapy. Liposomal drug delivery systems (LDDSs) are biocompatible, versatile nanocarriers that may overcome CSC-mediated resistance, but their clinical translation remains limited by…

Therapies based on genetically engineered immune cells (CAR T cells, HSCs) are transforming medicine, but the viral and electroporation methods used to create these cytoreagents are complex, expensive, and time-consuming. There is a growing need for transient "hit-and-run" genetic programming (transcription factors…

Genetic modification of T lymphocytes is essential for both basic research and immunotherapy (e.g., CAR-T cell generation), but existing methods rely on expensive commercial electroporation kits (Lonza Nucleofector® kits) or time-consuming viral vector production. The high cost and dependence on proprietary reagents…
