STING–NF-κB signaling builds an influenza spillover barrier Influenza pandemics are often traced back to the spillover of avian influenza A viruses (IAVs) to humans. However, barriers against IAV transmission remain elusive. We demonstrated human stimulator of...

Increasing evidence that STING has functions beyond DNA viruses. A new study reports that STING restricts influenza infection, independently of IFN. This work complements prior studies that STING prevents infection with diverse RNA viruses.

Hi Erik, I just wanted to follow up on being included in the science feed? Thank you!

Hi Dani, I wrote to be included in the science feed some time ago but my science communication posts with all the requested information but they don't appear here yet. Would you mind adding me to the list? Thank you!

Yeah both the authors and peer reviewers have clearly seemed to miss the point....

I'm not sure, often evaluation of the central dogma comes from a position of misunderstanding or superficial evaluation of the key tenet. The main point (that has yet to be violated) is that information does not flow backward from protein.

Chrysanthi Moschandrea and I have developed a new conceptual framework for understanding the role of metabolism in cancer, which we term metabolic permissiveness. We are eager to hear your thoughts on this topic.

Single Cell Glucose Uptake Assays: A Cautionary Tale Assays to monitor the metabolic state or nutrient uptake capacity of immune cells at a single cell level are increasingly in demand. One assay, used by many immunologists, employs 2-(N-(7-Nitrobenz-2-oxa-1,3-diazol-4-yl)Amino)-2-Deoxyglucose ...

****2-NBDG does not measure glucose uptake****

Just your regular reminder of this fact 😁.

See the rigorous proof of this fact in @lindavsinclair.bsky.social 2020 paper.

This paper was 6 years ago!! Stop using 2NBDG to measure glucose uptake already 🙄
