Researchers at the University at Albany’s RNA Institute have demonstrated a new approach to DNA nanostructure assembly that does not require magnesium. The method improves the biostability of the structures, making them more useful and reliable in a range of applications. The work appears in the journal Small this month.

When we think of DNA, the first association that comes to mind is likely genetics—the double helix structure within cells that houses an organism’s blueprint for growth and reproduction. A rapidly evolving area of DNA research is that of DNA nanostructures—synthetic molecules made up of the same building blocks as the DNA found in living cells, which are being engineered to solve critical challenges in applications ranging from medical diagnostics and drug delivery to materials science and data storage.

“In this work, we assembled DNA nanostructures without using magnesium, which is typically used in this process but comes with challenges that ultimately reduce the utility of the nanostructures that are produced,” said Arun Richard Chandrasekaran, corresponding author of the study and senior research scientist at the RNA Institute.

The limited ability of microrobots to assist drugs in entering cells hinders their therapeutic efficacy. To address this, a research team, reporting in Cyborg and Bionic Systems, has introduced the cancer-targeting molecule folic acid (FA) to microrobots to promote drug uptake by cancer cells via receptor-ligand-mediated endocytosis. This results in a drug delivery system that can locate lesion areas with magnetic fields and deliver loaded drugs into the cytoplasm through endocytosis.

Untethered microrobots have shown remarkable achievements in various fields such as minimally invasive surgery, drug delivery, environmental remediation, and tissue engineering. Magnetic field actuation is a widely used method due to its good biosafety, deeper tissue penetration, and high temporal and spatial control.

However, practical problems arise when microrobots delivering drugs may only be able to deliver the drugs to the area around the cells but cannot assist the drugs to enter the cells. This limitation could potentially reduce the effectiveness of the treatment since the drugs may not reach the intended targets within the cells.

Multiple sclerosis (MS) affects roughly 2.5 million people worldwide and is a neurological disease affecting the brain and spinal cord. More specifically, MS is when the immune system attacks the body’s protective layer around nerve fibers known as myelin sheaths. The breakdown of myelin sheath leads to a disconnect between your brain and body. The immune cells responsible for myelin sheath deterioration include CD4+ T cells, or effector cells, which are part of the body’s first line of defense. In MS, the effector cells do not recognize that the myelin sheath is a normal part of the body. Therefore, the effector cells become the dominant cell type, trying to kill and get rid of the myelin sheath. The immune response will generate inflammation which destroys the myelin sheath leading to a disruption of signals along the nerves from the brain to the body.

A group of researchers at Johns Hopkins University School of Medicine recently published a therapy that controls the symptoms of MS. The goal of the therapy was to stop effector cells from attacking the myelin sheath and to promote the production of T regulatory cells-or T regs-which have been demonstrated to reduce autoimmune effects.

Dr. Giorgio Raimondi, PhD, MSc, Jordan Green, and others used three therapeutic agents to control MS symptoms. Researchers used microparticles, which are small, bioengineered spheres to deliver the agents. The first agent is a combination of two proteins which include Interleukin-2 (IL2) and an antibody that promotes T reg production. IL2 stimulates T cell expansion, while the antibody blocks specific parts of IL2 to specifically expand T regs compared to effector cells. The second agent includes a molecule that presents a protein specific to myelin so that the immune response will generate T regs specifically designed to protect the myelin sheath. Finally, the third agent is rapamycin, which is an immunosuppressant drug designed to reduce effector T cells.

The 2020 Nobel Prize for Chemistry was awarded to Dr. Jennifer Doudna and Dr. Emmanuelle Charpentier for their work on the gene editing technique known as CRISPR-Cas9. This gives us the ability to change the DNA of any living thing, from plants and animals to humans.

The applications are enormous, from improving farming to curing diseases. A decade or so from now, CRISPR will no doubt be taught in High Schools, and be a basic building block of medicine and agriculture. It is going to change everything.

Legitimately awesome paper wherein Arulkumaran et al. assemble DNA nanotubes and use them to build artificial ‘cytoskeletons’ inside of giant unilamellar vesicles. They go on to make a variety of fun variations on this theme and eventually build artificial ‘tissues’ made up of these synthetic cell-like vesicles and an ‘extracellular matrix’ that is also made of DNA nanotubes. I find this paper impressive due to how performs precise engineering at the nanoscale and builds up layers of complexity until macroscale specimens are created in a fashion reminiscent of biological systems, yet unique in its own way. #biotechnology #nanotechnology #cellbiology #bioengineering

Building synthetic protocells and prototissues hinges on the formation of biomimetic skeletal frameworks. Here, the authors harness simplicity to create complexity by assembling DNA subunits into structural frameworks which support membrane-based protocells and prototissues.
