By adding synergistic self-adjuvanting properties to Covid-19 RNA vaccines, researchers showed they could significantly boost the immuneresponse generated in mice.
The reference, called the Immune Dictionary , appears today in Nature. Using single-cell RNA sequencing to analyze gene expression in individual cells, the researchers have found how 86 major cytokines affect 17 immune cell types in mice. For many immune-mediated diseases, there's no cure or treatment.
When faced with a viral threat, bacterial cells developed an immuneresponse by capturing and copying DNA fragments of viruses. It was also discovered that the Cas enzyme was responsible for DNA cleavage. Using a synthetic guide RNA (gRNA), scientists can target a specific DNA sequence and employ Cas9 to cut it.
In research published in Scientific Reports , 1 investigators focused on mesenchymal stem cells (MSCs), known for their potential in treating cell defects and regulating immuneresponses. In the lab, they labelled RNA molecules with fluorescent markers, enabling them to easily locate them within individual cells.
Natural killer (NK) cells are another immune cell type that, as the name suggests, also have potent cell-killing activity, and have a well-known role in the anti-tumour immuneresponse. In the context of a tumour microenvironment, Tregs are often present in high numbers, preventing an effective immuneresponse to the tumour.
“Sam has an exceptional talent in software engineering, and his contributions reflect a deep understanding of both the technical and biological aspects required for bioinformatics tool development,” says Laura Luebbert, now a postdoctoral fellow in the Sabeti lab at the Broad Institute of MIT and Harvard and Harvard University.
Better activation of innate and adaptive immuneresponses was achieved with CV2CoV, resulting in faster response onset, higher titers of antibodies, and stronger memory B and T cell activation as compared to the first-generation candidate, CVnCoV. “In Induction of innate immunity was investigated via specific cytokine markers.
Scientists from the Massachusetts Institute of Technology (MIT) and the University of Massachusetts Medical School (UMass), US, have collaborated to create a novel type of nanoparticle that can deliver messenger RNA that encodes for beneficial proteins to the lungs.
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. Online June 27, 2024.
The drugs work by blocking a protein, PD-1 — which helps keep immuneresponses in check — and stimulating the immune system to attack tumors. The team studied the immuneresponse to CRISPR and designed a new technology that they published in 2021 — a way of removing immune-triggering molecules from CRISPR-edited cells.
Treatment with mIDH1 blockers unearths these remnants, triggering an immuneresponse against the tumor cells. IDH1 normally facilitates the activity of enzymes called demethylases, which remove chemical flags called methylation marks from DNA, allowing genes to be transcribed into RNA.
But, regardless of which was first, they all operated with the same core data as their mechanism for understanding life: messenger RNA ( mRNA ). Prior therapeutic viruses had had their replication capabilities crippled out of fear of severe immuneresponses. There was scFormer in 2022, scGPT in 2023, and plenty of others.
Tissue engineering techniques using induced pluripotent stem cells (iPSC), which are differentiated into cardiomyocytes, are being developed to create functional cardiac tissues from patient-derived cells. RNA-based therapies, including mRNA and RNA interference (RNAi), are being explored to modulate gene expression in heart cells.
If present before vaccination, memory immune cells primed to destroy the environmental relatives might cross-react with and neutralize the BCG strain before it has a chance to set up an immuneresponse against itself and M. Testing the engineered cells against four common drugs, I found that the M. tuberculosis.
We had built a machine learning classifier that has been trained to identify amino acid sequences that have the potential to mimic ‘host defense peptides’ from the human innate immune system. Such peptides play a critical role in the machinery for amplifying innate immuneresponses.
DNA and RNA molecules are also built from exclusively right-handed nucleic acids. As Richard Dawkins said of biological wheels : “the engineering solution can be seen in plain view, yet [it is] unattainable in evolution because it lies [on] the other side of a deep valley.”
Anderson Professor of Chemical and Biomolecular Engineering, and his colleagues, are reporting in iScience the event of an intranasal subunit vaccine that gives durable local immunity against inhaled pathogens. A fundamental limitation of intramuscular vaccines is that they’re not designed to elicit mucosal immunity.
LanzaTech announced a partnership with H&M Move to convert factory carbon emissions into fabrics using engineered microbes. Small snippets of double-stranded RNA were sprayed onto hot pepper plants to control a pest, called Frankliniella occidentalis. RNA may offer a safer form of pest control in the future. Shrock E.L.

Often, when we engineer a cell, we only mess with the magnitude of an effect; this study suggests that we should think more about the timing, too. From Zhang et al.

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. Because it turns out that at least half of them , in humans, also bind to RNA molecules. RNA export systems.

As research developments into RNA vaccines help scientists accelerate drug candidates to arm the immune system against coronavirus, Pharma IQ ’s Keeping tabs on Covid-19 update returns with news from some of the biotechnology innovators leading the fight against the global pandemic.
The vaccine targeted both the inner nucleocapsid (N) and the outer spike (S) proteins of the virus to maximize the immuneresponse. The study showed this broad immuneresponse led to the complete clearance of the virus in a matter of days after infection of previously-vaccinated primates.
In the new study, they homed in on a handful of these genes encoding enzymes that are members of the STAND ATPase family of proteins, which in eukaryotes are involved in the innate immuneresponse. Most known bacterial defense systems work by sensing viral DNA or RNA, or cellular stress due to the infection.
A gene encoding green fluorescent protein was placed alongside one of the three promoters, and as the engineered cells cycled from one gene to the next, they blinked between green—dark—green—dark. The RNA Exporter , which was developed by Felix Horns and others in my lab, is one example. Another one is immunogenicity.
Fitusiran is an investigational, subcutaneously administered small interference RNA therapy in development for the treatment of people with hemophilia A or B, with or without inhibitors and has the potential to transform treatment as it would be the only prophylactic therapy with as few as six injections per year.
Galidesivir is a broad-spectrum antiviral, an adenosine nucleoside analog that blocks viral RNA polymerase. STP705 is a small interfering RNA (siRNA) therapy that leverages a dual-targeted inhibitory property and polypeptide nanoparticle (PNP)-enhanced delivery to knock down both TGF-beta1 and COX-2 gene expression.

RNA polymerase — the enzyme responsible for replicating influenza’s genetic material — lacks proofreading abilities, meaning that mutations aren’t corrected and can rapidly accumulate. The vaccine must cross the mucosal barrier, ignite a robust immuneresponse, yet not cause excessive inflammation.
Interferon gamma release assays pick up an immuneresponse to the infection. tuberculosis known as rpoB , which codes for part of its RNA polymerase. tuberculosis in his system, his T cells will recognize the antigen and mount an intense immuneresponse at the injection site, leaving behind a red and swollen bull’s-eye.
Codon Digest is my weekly roundup of research, news, and industry highlights about engineered biology. Skin microbes can trigger strong immuneresponses.

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. Unfortunately, they can also trigger immuneresponses, and they are not super efficient at gene-editing some parts of the brain. Ming Li et al.
