Must mRNA be cloaked in a lipid coat to serve as a vaccine?

The Uchida Laboratory of Innovation Center of NanoMedicine has demonstrated that intradermal administration of mRNA alone (naked mRNA) without protection by nanoparticles induced robust vaccination against SARS CoV-2, a virus ...

Q&A: The engineer who delivers mRNA inside human cells

Messenger RNA became a household term when it was used as the backbone of the first COVID-19 vaccines, especially after the Nobel Prize was awarded to two mRNA pioneers at the University of Pennsylvania.

Designing nanoparticles for pregnancy-safe treatments

Too often, the lack of clinical trials means that pregnant women suffer because available medications are prescribed off-label for them or not at all. A new study offers proof of concept for the important parameters to develop ...

Silencing a gene could lower cholesterol

Durable repression of a gene that has a role in controlling cholesterol levels, achieved without permanent genome editing, has been demonstrated in a mouse study published in Nature this week.

Nanoparticles amplify potential cancer vaccine power

Johns Hopkins researchers have identified minuscule particles that supercharge therapeutic cancer vaccines, which train the immune system to attack tumors. These new lipid nanoparticles—tiny structures made of fat—not ...
