Williams January 8, 2024 Credit: Susanna Hamilton, Broad Communications Researchers have developed virus-like particles that can deliver gene-editing cargo to cells, including those in the mouse brain. By Sarah C.P. However, delivering the complex gene editing machinery to cells in living animals has been challenging.
Building on previous work by the vector-engineering lab of Ben Deverman at the Broad, the team developed a pair of adeno-associated viruses (AAVs) to package and deliver the base-editing machinery to brain cells. But the researchers needed to deliver the base editors to the brain.

By Allessandra DiCorato July 19, 2023 Credit: Kevin Middleton, Broad Communications A three-dimensional model of adeno-associated viruses (AAVs), which scientists have engineered to package and deliver gene therapies to cells in the body. Qin Huang, a senior research scientist in Deverman’s group, is the first author on the study.
To deliver CHARM throughout the brain, the team collaborated with scientists in the lab of Ben Deverman , senior director of vector engineering at the Broad and a co-author of the study. They used an engineered adeno-associated virus (AAV) that crosses the blood-brain barrier after intravenous administration.
Existing methods of engineering one of the most commonly used gene-delivery vehicles, adeno-associated viruses (AAV), are often slow and inefficient. Now, researchers at the Broad Institute of MIT and Harvard have developed a machine-learning approach that promises to speed up AAV engineering for gene therapy. Nature Communications.
The other study was led by senior authors Xiao Wang , a Broad core institute member, a Merkin Institute Fellow, and an assistant professor of chemistry at MIT, and Jia Liu, an assistant professor of engineering at Harvard University. Our atlas represents the largest spatial single-cell dataset our lab has analyzed to date,” said Wang.
doi: 10.2210/rcsb_pdb/goodsell-gallery-048 The Virus that Cures It’s been over 25 years since the science magazine Discover first ran an extraordinary article about how a long-forgotten medical treatment, used in the former Soviet country of Georgia, could save us from the growing threat of untreatable, drug-resistant infections.
Some are focused on viruses called adeno-associated viruses (AAVs), which have been engineered to act only as a one-time delivery vehicle and not cause disease. Broad researchers are further engineering AAVs to efficiently deliver gene-based therapies to tissues that have been difficult to reach, such as the muscle and brain.
Spectrum’s self-contained saliva collection kit provides critical sample consistency while suspending and neutralizing viral RNA transcripts completely inactivating the live virus.
“The SDNA-1000 was engineered to innovate molecular diagnostic applications using saliva,” said Jeremy Johnson, VP of Engineering at Spectrum Solutions.
2,3 Engineering both the capsid and DNA cargo improves the safety and efficacy of rAAV vectors and expands their clinical applications. Adeno-associated virus as a delivery vector for gene therapy of human diseases. Adeno-associated virus-based gene therapy for lifelong correction of genetic disease. Labcompare. 2024;9(1):78.
The package insert for the drug, Elevidys , warns of adverse effects of acute liver injury and inflammation around the heart and muscles. First, adeno-associated virus (AAV) delivers the genes, rather than the adenovirus (AV) that had entered cells in Jesse’s liver that weren’t the targets. Cardiac markers were okay.
Codon Digest is my weekly roundup of research, news, and industry highlights about engineered biology. An engineered version of this protein can convert DNA bases with efficiencies up to 92%. This means that IscB base editors might be easier to package inside of AAVs, which can only store 4,700 bases of DNA for gene therapies.

Secondly, circRNAs can be engineered for more efficient protein expression by carefully selecting and optimising the IRES element, a sequence motif derived from viruses and used to initiate cap-independent translation from circRNA. We are now running follow-up experiments to track the advantage long-term.

But for a recent paper out of Nanjing, China, researchers engineered another enzyme and showed that, when mixed with FAST-PETase, the two worked together to break down plastic twice as fast as the Texas enzyme alone. Two of these proteins are about 30% the size of Cas9 , and thus much easier to package into viruses for gene therapy.

“These data show consistent, high levels of efficacy and reaffirm the ability of the vaccine to prevent COVID-19 amid ongoing genetic evolution of the virus. Variant Virus Strains. against the original virus strain, 86.3% It is packaged in a ready-to-use liquid formulation in 10-dose vials. Glenn, M.D.,
The research is part of an ongoing collaboration between Columbia University and Tonix that focuses on T cell and antibody responses to SARS-CoV-2 (CoV-2), the virus that causes COVID-19. The research encompasses two projects. The study led by Dr. Ilya Trakht, Ph.D., About TNX-1800.
Prevention of viral contamination is especially important as it may not be apparent that cells have been contaminated with a virus using conventional detection methods. Likewise, the selection of a cell line that was developed using a virus increases the risk of potential viral contamination.
The prebiotic may either feed the probiotic that it is packaged with, or it may feed another beneficial microbe that is intended to complement the activity of the probiotic. However, the term synthetic biotic is typically reserved for genetically engineered bacteria that intend to target a specific condition.
I’m writing long essays for Asimov every other week and my work at MIT, where I’m helping to design a genetic engineering curriculum for undergraduates, has reached its crescendo. Anyone who has tried to engineer a cell knows how tedious it can be. A phage is a virus that infects bacteria. ” So take it easy!

Once the mosquito factory has made all these insects, they are packaged into boxes or cups and then released in “strategic” areas within a city, like near swampy water or in dengue-ridden neighborhoods. But I do know this: Genetic engineering has endowed us with a radical ability to control our environments.

” By the 1850s, the Capitol was renovated to include a ventilation system featuring 14-foot rotary fans driven by subterranean steam engines. In 1965, Congress mandated labeling on all cigarette packaging that warned consumers about the risks of smoking. This included the most rudimentary of ventilation tools: windows.
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. Genetic engineering can be used to eradicate mosquitoes in two ways: Through gene drives or the “sterile insect technique.” in bioRxiv.

Making a computer-designed protein in the laboratory requires, first, that scientists synthesize a string of DNA encoding the protein, insert that DNA into living cells, and then isolate the proteins churned out by the engineered cells. The world’s supply of insulin is now made by engineered microbes.
To achieve this, E11 Bio synthesizes protein barcodes (short peptides with unique amino acid sequences), packages them into AAV vectors (engineered, non-harmful viruses for drug delivery), and delivers these into the brain tissue.
