Inflammation is the sign that our body is defending itself against an aggression. But when this response escalates, for example in the brain, it can lead to serious neurological or psychiatric diseases. A team investigated a marker protein targeted by medical imaging to visualize cerebral inflammation, but whose interpretation was still uncertain. The team reveals that a large quantity of this protein goes hand in hand with a large quantity of inflammatory cells, but its presence is not a sign of their overactivation. These results pave the way for optimal observation of neuroinflammatory processes and a re-reading of previous studies on the subject.

Among available immunotherapies, the use of 'CAR-T' cells is proving extremely effective against certain blood cancers, but only in half of patients.

By inhibiting a very specific metabolic mechanism, the team has succeeded in creating CAR-T cells with enhanced immune memory, capable of fighting tumor cells for much longer.

Researchers provide essential insights on the molecular activation of the MAP kinase p38?, 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.
