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.
Reporting in Science , researchers at Massachusetts General Hospital and the Broad Institute of MIT and Harvard have made a surprising discovery about these drugs. They found that mIDH1 inhibitors trick the tumor cells into thinking they are infected with a virus, causing the immune system to mount an antiviral response.
The drugs work by blocking a protein, PD-1 — which helps keep immuneresponses in check — and stimulating the immune system to attack tumors. The researchers soon partnered with Calico Life Sciences , which in collaboration with AbbVie , discovered drug candidates that block the PTPN2 protein.
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.
These factors are converging to enable both identification of novel infectious diseases as well as microbial resistance, before these threats can impact public health, write a team from the European Society for Clinical Microbiology and Infectious Diseases in Frontiers in Science. Work on vaccines ensued too.

One thread that has run throughout it has been my passion for science as a lens for looking at the world. In particular, I love connecting science to daily life. Pfizer’s recent campaign around “ Science Will Win ” similarly appealed to the ethos of the power of science to help humanity. Remember life’s Central Dogma.
Making a little tangle of DNA visible to the eye and understanding that this is the basis of complex organisms, which might be altered in disease, was the defining moment for my future path in life sciences. Communication and networking are key in any career, with science being no exception.
” The report accompanies an article in Science , also released today, entitled “Confronting Risks of Mirror Life.” For the article in Science , more than 30 scientists from ten countries are calling on the broader community to confront the risks of mirrored life. ” But what, exactly, is a mirrored organism?
This method was more about serendipity than science. Another promising avenue is the use of technologies like RNA interference and gene editing, which allow scientists to turn off the production of certain proteins altogether. But as molecular biology has advanced, so too has our approach to finding new drugs.
Strong Th1 cell-mediated immuneresponses were also observed for the vaccine candidates with either adjuvant. We are encouraged by the high level of neutralizing antibodies in combination with the strong Th1 response which we believe could play an important role in controlling infection.
AAV-based therapies often can’t be dosed more than once due to concerns about an immuneresponse. Additionally, the COVID-19 RNA vaccines have already demonstrated how safe RNA can be, and we look forward to seeing additional safety data on RNA approaches as the field continues to grow.

But, regardless of which was first, they all operated with the same core data as their mechanism for understanding life: messenger RNA ( mRNA ). While mRNA data was often illuminating, their interpretation was tricky; more akin to art than science. There was scFormer in 2022, scGPT in 2023, and plenty of others.
Adjuvanted S-Trimer COVID-19 vaccine candidates demonstrated favorable safety and tolerability profiles and strong neutralizing immuneresponses in a phase 1 trial.
GSK is a science-led global healthcare company with a special purpose: to help people do more, feel better, live longer.

As soon as I learned about DNA and RNA, I wanted to be a molecular biologist. Last stops at RNA My last roles in biotech were where my original passion began: DNA and RNA. My last stop at Arrakis Therapeutics is with a company targeting RNA with small molecules. I wanted to use molecular biology to create drugs.
The study appears in Science. 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. Prokaryotic innate immunity through pattern recognition of conserved viral proteins.
The Phase 1 interim analysis showed that mRNA-1273 was generally well-tolerated across all age groups and induced rapid and strong immuneresponses against SARS-CoV-2. Moderna is advancing messenger RNA (mRNA) science to create a new class of transformative medicines for patients. 26, 2020 11:00 UTC. CAMBRIDGE, Mass.–(
Dr Ashley Seifert, an associate professor in the Department of Biology at the UK College of Arts and Sciences, and his research group have pioneered the use of spiny mice and other animal models to understand how complex tissue can regenerate, bridging regenerative biology and medicine. The Innate ImmuneResponse to Infection [Internet].
“Computer science is to biology what calculus is to physics.” 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. My goal is to reach 100 supporters!
Immunization of non-human primates (rhesus macaques) with BNT162b2, a nucleoside-modified messenger RNA (modRNA) candidate that expresses the SARS-CoV-2 spike glycoprotein, resulted in strong anti-viral effects against an infectious SARS-CoV-2 challenge. producing CD8+ T cell responses, which is thought to promote an anti-viral effect.
From an article in Science : “After 6 months, the most promising varieties had their lignin content reduced by 49.1% in Science. Their cone cells, which are responsible for color vision, don’t work like normal. Because it turns out that at least half of them , in humans, also bind to RNA molecules.

But HIV’s ability to mutate isn’t unique among RNA viruses – most viruses develop mutations, or changes in their genetic code, over time. ” In the same time period, mRNA vaccines were being deployed and immuneresponses to those vaccines were being studied.
The messenger RNA (mRNA) vaccines encode a form of the spike (S) protein of SARS-CoV-2 virus. The vaccine teaches the cells to make a piece of the spike protein, which triggers an immuneresponse to help prevent illness if later exposed to the virus.
How do they work?
The Moderna COVID-19 Vaccine contains messenger RNA (mRNA), which is genetic material. After a person receives this vaccine, their body produces copies of the spike protein, which does not cause disease, but triggers the immune system to learn to react defensively, producing an immuneresponse against SARS-CoV-2.

I remember my sister being held down to get her triple vaccine, then given in two shots in the arms, which DNA Science covered here. Another subset of T cells, called memory cells, enable a rapid immuneresponse should the person encounter the pathogen again.
I’m the same age as RFK Jr, and a geneticist and science writer. All 38 editions of the life science textbooks I’ve written have chapters on immunology that clearly define vaccine: “an inactive, disabled, or part of a pathogen that stimulates an immuneresponse. I know that because I helped write them.
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.
Skin microbes can trigger strong immuneresponses. These microbes were engineered to express tumor antigens that could “elicit T cells that were licensed by the commensal immune program but specific for a tumor,” including both CD4+ and CD8+ T cells, according to the study.
