Also, last week’s digest had an error: The country that approved the malaria vaccine was Ghana. Vaccines (basically little fat bubbles filled with mRNA and some dissolvable polymers) were physically printed onto microneedle patches using a robot. The patches have little spikes that help push the vaccines through the skin.

Scientists at the Institute for Protein Design have crafted proteins that self-assemble into nanomaterials or that can be used as vaccines for the flu and HIV. All cells make proteins in two steps: DNA is transcribed into messenger RNA, which is then translated into protein. Some catalyze reactions 30 million times per second.
The speed at which researchers developed effective vaccines to prevent the spread of COVID-19 required unprecedented international cooperation on a scale never seen before. Rollout of approved vaccines is underway in many countries across the globe, giving people hope that the end to the pandemic is finally in sight.
The researchers first compared the editing efficiency of different versions of IscB when coupled with 'ωRNA,' which guides the enzyme to the right spot on the DNA. A particular variant, named IscB*-ωRNA*, had the highest editing efficiency across multiple different sites in the genome. Read more in Nature Methods.

This is especially applicable to labs involved in the development of highly sought-after viral therapeutics and vaccines. Viral plaque assays are standard tools in the development of antiviral drugs and vaccines, but this method is traditionally time-intensive and error prone due to manual counting. Sources Zhang et al.
Small snippets of double-stranded RNA were sprayed onto hot pepper plants to control a pest, called Frankliniella occidentalis. The RNA strands shut down a specific gene in the insects, and killed half after 7 days. RNA may offer a safer form of pest control in the future. npj Vaccines. Robinson A.O. Nature Biotechnology.
Sequencing viral genome isolates and creating phylogenetic trees Sequencing a viral genome requires isolating the viral RNA, reverse transcribing it into DNA, and then performing multiple amplification steps using primers. Studying viral mutation is critical for designing effective vaccines, antiviral drugs and diagnostic assays.
Research in gene therapies and genetically engineered drugs and vaccines are growing exponentially, and will only continue to become more popular. Diving deeper, this blog explores how research sites are focusing on their institutional biosafety committee (IBC) programs as part of overall study activation time.
Read A new DNA polymerase variant, called RT-KTq I614Y, can directly detect RNA modifications, including pseudouridine (Ψ) and queuosine (Q). By combining this new variant with standard sequencing methods, it’s possible to identify RNA modifications in a really simple way. Nucleic Acids Research. Communications Biology.
This approach is facilitated by developing ASOs and RNA interference (RNAi) therapies, which target the various molecular and genetic mechanisms contributing to ALS pathophysiology and disease progression. For a more in-depth discussion on challenges and solutions to ALS research, read our blog.
In those early days, politicians and government officials who’d never heard terms like “cytokine storm” and “RNA virus” were suddenly charged with explaining what was happening. ” Twenty years later, his DYOR fueled the anti-vaccine movement, countering decades of evidence that vaccines work.
That progress includes the development of life-preserving monoclonal antibody infusions and repurposing existing drugs , to which NIH’s Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV ) public-private partnership has made a major contribution. November 5, 2021. [3] Food and Drug Administration. October 14, 2021.
But, regardless of which was first, they all operated with the same core data as their mechanism for understanding life: messenger RNA ( mRNA ). The longevity treatments that had emerged in the 2040s had become as commonplace as vaccines. He also writes for a blog focused on the intersection of biology and AI at owlposting.com.
Made from a Cas9 nickase (the histidine at amino acid position 840 is swapped for an alanine) fused to a reverse transcriptase enzyme (which makes DNA from RNA; transcription in reverse), prime editing clinical trials are expected to begin by 2025. link ) INSPECTR is a diagnostic tool to detect tiny amounts of viral RNA at room temperature.

The central dogma is often depicted as DNA→RNA→protein, but it’s much more: A biophysical marvel inside the smallest of vessels. The landmark paper enabled revolutions in insulin biomanufacturing, CAR-T therapies, and the bioproduction of most modern vaccines; in other words, much of what we take for granted today.
Most people would take the two CRISPR gene-editing components (a Cas9 protein and guide RNA), package them up inside of a virus, and then inject the viruses into the skulls of mice. Promising new malaria vaccine for kids approved in Ghana. This is not the first vaccine approved to prevent malaria, but it is by far the most effective.

This gene-editing system consists of a short segment of RNA that is attached to an enzyme. The RNA is preprogrammed to find a distinct short sequence of DNA and deliver the enzyme, which acts like a scalpel to slice the sequence out of the genome. It’s fast and pretty precise. NIAID scientists, led by Drs. Protein Cell.

PPD, Thermo Fisher Scientific’s clinical research business, surveyed more than 150 biotech and biopharma leaders this year to assess trends in the drug development industry, yielding data we’ll cite throughout this blog. Novel therapeutic platforms will drive developments in priority therapeutic areas.
With infectious diseases on the rise, she asked me to repost CDC’s Adult Vaccine Assessment Tool. could head Health and Human Services, and friends asking me which vaccines they needed to update or get for the first time. Which Vaccines Require Boosters? But which other vaccines should my daughter and her cohort get?
A few weeks ago, I noticed a surprising metric when posting my weekly DNA Science blog – at year’s end, I’d hit #500! Looking back, which blog post was the most important? Martin’s Press was about to publish my book about gene therapy in 2012, my agent urged me to start blogging. That got me thinking.
