Rapid host adaptations in response to viral infections
Viruses threaten all living organisms leading to molecular conflicts which have shaped hosts over evolutionary timescales. This meeting seeks to gather scientists from diverse disciplines including genomics, population genetics, innate immunology, virology, and beyond, to explore the evolution, diversity, molecular basis, and dynamics of these conflicts.

Our latest paper on bat Dicer! 🦇 we show that Dicer antiviral RNAi activity is context-dependent also in bats 👩‍🔬 Specifically in Myotis myotis nasal epithelial cells, Dicer relocalizes to sites of viral replication upon alphavirus infection, which correlates with a proviral activity of Dicer 🦠

Vaccines work! As measles cases have recently been reported in Alaska, Georgia, New York, Rhode Island and Texas, it's important to remember that prior to the introduction of the measles vaccine in 1963, measles killed 400-500 people and resulted in ~48,000 hospitalizations per year.
Graph showing that prior to 1963 when the measles vaccine was introduced, there were around 300,000-700,000 measles cases per year. Within a few years of the vaccine, the number of cases fell below 20,000/year. There were a blips where cases rose, but shortly after the second vaccine dose was recommended in 1989, annual cases have generally been well below 1,000 cases. In 2000, measles elimination was declared in the US. Now we have sporadic outbreaks that typically spread among unvaccinated people. Chart is from Center for American Progress and is based on CDC data on measles cases.

And more:

Data on the CDC's website are being removed to comply with the Trump administration’s ongoing attempt to scrub federal agencies of any mention of gender, DEI, and accessibility, @katherinejwu.com reports. 9/x
CDC Data Are Disappearing
The agency has already removed scientific data from public view. More could follow.

1/n So, this is out in NAR, finally. The longest, the most expensive and the most challenging project in the lab. Sparked by controversy concerning mammalian antiviral RNAi and our identification of Dicer variant, which is sufficient to increase RNAi.

Enhanced RNAi does not provide efficient innate antiviral immunity in mice
Abstract. In RNA interference (RNAi), long double-stranded RNA is cleaved by the Dicer endonuclease into small interfering RNAs (siRNAs), which guide degra
