Soft-landing methods aim to simplify structural biology

Linking mass spectroscopy with cryo-electron microscopy could transform understanding of complex protein structures — if scientists can show that samples remain intact when they hit their target.

Switching off the cytokine storm

In a new paper published in Science, EMBL Grenoble researchers provide essential insights on the molecular activation of the MAP kinase p38α, the final switch triggering the inflammatory response.
Inflammation is a cellular coping mechanism when confronted with stress, such as an infection. However, too much inflammation can damage the functioning of cells and organs. This is the case with cytokine storms, inflammatory cascades that can lead to severe disease and death, recently highlighted during the COVID-19 pandemic.
These results open up new directions to develop drugs to prevent cytokine storms and to study similar processes in two other families of MAP kinases, involved in cancer and Alzheimer’s disease respectively. ....
