DNA nanotechnology is a unique field, where physics, chemistry, biology, mathematics, engineering, and materials science can elegantly converge. Since the original proposal of Nadrian Seeman, significant advances have been achieved in past four decades. During this glory time, origami technique developed by Paul Rothemund further pushed field forward with vigorous momentum, fostering plethora concepts, models, methodologies, applications that were not thought before. This review focuses on recent progress origami-engineered nanomaterials five years, outlining exciting achievements as well unexplored research avenues. We believe spirit assets Seeman left for scientists will continue to bring interdisciplinary innovations useful next decade.

Enhancing antibody responses by multivalent antigen display on thymus-independent DNA origami scaffolds

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Янв. 30, 2024

Protein-based virus-like particles (P-VLPs) are commonly used to spatially organize antigens and enhance humoral immunity through multivalent antigen display. However, P-VLPs thymus-dependent that themselves immunogenic can induce B cell responses may neutralize the platform. Here, we investigate thymus-independent DNA origami as an alternative material for display using receptor binding domain (RBD) of SARS-CoV-2 spike protein, primary target neutralizing antibody responses. Sequential immunization mice with DNA-based VLPs (DNA-VLPs) elicits protective antibodies in a manner depends on valency displayed T help. Importantly, immune sera do not contain boosted, class-switched against scaffold, contrast elicit strong memory both scaffold. Thus, DNA-VLPs immunogenicity without generating scaffold-directed thereby offer important particulate vaccine design.

The clustering of death receptors (DRs) at the membrane leads to apoptosis. With goal treating tumours, multivalent molecular tools that initiate this mechanism have been developed. However, DRs are also ubiquitously expressed in healthy tissue. Here we present a stimuli-responsive robotic switch nanodevice can autonomously and selectively turn on display cytotoxic ligand patterns tumour microenvironments. We demonstrate switchable DNA origami normally hides six ligands but displays them as hexagonal pattern 10 nm diameter once under higher acidity. This effectively cluster trigger apoptosis human breast cancer cells pH 6.5 while remaining inert 7.4. When administered mice bearing xenografts, decreased growth by up 70%. data feasibility opportunities for developing switches path targeted treatment.

Evaluation of Nonmodified Wireframe DNA Origami for Acute Toxicity and Biodistribution in Mice

ACS Applied Bio Materials, Год журнала: 2023, Номер 6(5), С. 1960 - 1969

Опубликована: Апрель 11, 2023

Wireframe DNA origami can be used to fabricate virus-like particles for a range of biomedical applications, including the delivery nucleic acid therapeutics. However, acute toxicity and biodistribution these wireframe nanoparticles (NANPs) have not been previously characterized in animal models. In present study, we observed no indications BALB/c mice following therapeutically relevant dosage nonmodified DNA-based NANPs via intravenous administration, based on liver kidney histology, biochemistry, body weight. Further, immunotoxicity was minimal, as indicated by blood cell counts type-I interferon pro-inflammatory cytokines. an SJL/J model autoimmunity, NANP-mediated DNA-specific antibody response or immune-mediated pathology intraperitoneal administration NANPs. Finally, studies revealed that accumulate within one hour, concomitant with substantial renal clearance. Our observations support continued development next-generation therapeutic platforms.
