The Long History of mRNA Vaccines - Johns Hopkins
2021年10月6日 · Messenger RNA, or mRNA, was discovered in the early 1960s; research into how mRNA could be delivered into cells was developed in the 1970s. So, why did it take until the global COVID-19 pandemic of 2020 for the first mRNA vaccine to be brought to market?
Understanding COVID-19 mRNA Vaccines - National Human …
2021年8月30日 · Messenger RNA (mRNA) is a molecule that encodes a sequence that can be made into a protein. Scientists first learned about mRNA nearly 60 years ago, and researchers have been studying vaccines using mRNA for decades. The earliest COVID-19 vaccines authorized for use in the United States by the Food and …
Messenger RNA (mRNA) | Description & Function | Britannica
2024年10月29日 · messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes). The molecule that would eventually become known as mRNA was first described in 1956 by scientists Elliot Volkin and Lazarus Astrachan.
The tangled history of mRNA vaccines - Nature
2021年9月14日 · In late 1987, Robert Malone performed a landmark experiment. He mixed strands of messenger RNA with droplets of fat, to create a kind of molecular stew. Human cells bathed in this genetic gumbo...

4 天之前 · Messenger RNA (abbreviated mRNA) is a type of single-stranded RNA involved in protein synthesis. mRNA is made from a DNA template during the process of transcription.
mRNA Technology: What It Is and How It Works - Pfizer
mRNA—or messenger RNA—is a molecule that contains the instructions or recipe that directs the cells to make a protein using its natural machinery. To enter cells smoothly, mRNA travels within a protective bubble called a Lipid Nanoparticle.
COVID-19 mRNA Vaccine Production - National Human Genome …
2021年8月31日 · Once a sequence is selected, a new plasmid can be produced within a couple of weeks, allowing new mRNA vaccines to be tested and distributed rapidly. Researchers then use established in-vitro (laboratory-based, such as in a test tube) protocols to create mRNA in a method that mimics our own biological processes.

2020年11月10日 · For decades, scientists have dreamed about the seemingly endless possibilities of custom-made messenger RNA, or mRNA. Researchers understood its role as a recipe book for the body’s trillions of...
How Drew Weissman and Katalin Karikó Developed the mRNA …
2021年11月18日 · Modern medicine was transformed in an instant. But the story of how scientist Drew Weissman (MED’87, GRS’87) and his research partner Katalin Karikó developed the revolutionary mRNA technology that powers the world’s most effective COVID-19 vaccines was a much slower burn—one that easily could have flickered out.
How mRNA technology came to the rescue - Nature
For decades after mRNA was first isolated in the 1960s, scientists worked to understand how it might help fight disease — using the body’s instruction manual to replace defective proteins or ...
