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…

Gene therapy requires safe and effective delivery vectors. PBAEs are biodegradable cationic polymers with excellent gene delivery properties, but a comprehensive and critical overview of their use as gene carriers is lacking. This review provides the first comprehensive and critical overview of PBAE-based gene…

Conventional micro/nanoparticle synthesis techniques (e.g., emulsion, sol–gel) can produce only a limited number of shapes—mainly spherical or rod-like—and provide poor control over size, cargo loading, and surface properties. These features critically affect particle–cell interactions and in vivo biodistribution, so…

Polarized endocytic recycling of the T cell receptor (TCR) to the immunological synapse is essential for T cell activation, yet the cellular mechanisms that coordinate internalisation of surface receptors with sustained delivery back to the plasma membrane remain incompletely understood. The role of flotillins in…

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…

Artificial antigen-presenting cells (aAPCs) are promising for immune modulation, and anisotropic (ellipsoidal) particles have shown improved T-cell stimulation over spherical particles. However, widely used methods for generating anisotropic particles, such as thin-film stretching, can be difficult to implement…

Dendritic cell (DC)-based cancer immunotherapy is promising but limited by poor antigen immunogenicity, weak stability, and short in vivo half-life. Nanotechnology can protect antigens and adjuvants from premature degradation, enhance delivery to DCs, and improve therapeutic T cell responses. This review summarises…

Free siRNA, mRNA, pDNA, and CRISPR/Cas9 components are rapidly degraded and cleared, so delivery systems are required. LNPs are the most clinically advanced non-viral siRNA carriers; Patisiran reached Phase III and market application in late 2017. The field needed a clearer understanding of LNP design parameters and…

Biodegradable polymeric nanoparticles have great potential to improve cancer therapy by enabling targeted delivery, triggered release, and reduced off-target toxicity. This review addresses how such nanocarriers can be engineered to overcome systemic, organ-level, and cellular barriers and to target cancer cells…

Nucleic acids can be used to engineer the immune system, but their clinical use requires better specificity and intracellular delivery efficiency. Viral vectors have manufacturing, cargo-capacity, safety, and immunological drawbacks; therefore, polymers are being developed as non-viral delivery vehicles whose…

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…

Systemic immune stimulation for cancer immunotherapy is associated with autoimmune-type pathologies, as the doses required to break immune tolerance can invoke undesired host-vs.-host effects. Targeting endogenous immune cell subsets in the circulation—which actively migrate into tumours—could concentrate…

Efficient cancer vaccine carriers need both antigen delivery to dendritic cells (DCs) and DC activation. Previous pH-sensitive polymer-modified liposomes delivered antigen to DC cytosol but had limited adjuvant potency, and combining cationic lipid TRX with MPLA reduced antitumor effects, suggesting a need for…

Whole tumour cell lysates (TCL) are a broad source of tumour antigens for cancer vaccines, but soluble TCL is unstable, poorly taken up by dendritic cells (DCs), and inefficient at inducing cytotoxic T lymphocyte (CTL) responses. A delivery system was needed to protect TCL antigens, target DCs, and enhance antigen…

mRNA therapeutics have enormous potential for vaccines, cancer immunotherapy, protein replacement, and gene editing, but widespread clinical application is limited by the lack of safe and effective delivery vehicles. Naked mRNA is large (~10⁵–10⁶ Da), densely negatively charged, and rapidly degraded by nucleases; its…

Nonviral DNA delivery remains inefficient, and the barriers limiting transfection are incompletely understood.

mRNA vaccines are promising for inducing cytolytic CD8⁺ T cell responses, and lipoplex carriers improve mRNA delivery to dendritic cells. However, the innate factors that regulate T cell induction by mRNA lipoplex vaccines remain unresolved. In particular, type I interferons (IFNs) are induced by mRNA but can either…
