Our latest work from @brozlab.bsky.social and led by @alexandraboegli.bsky.social is out now in @embojournal.org. Check out our findings on how the intestinal #inflammasome NLRP6 senses lysosomal damage to trigger pyroptotic cell death.

Für Naturwissenschaftliche Fächer haben übrigens doppelt so viele Männer, die John heißen , einen Nobelpreis gekriegt, wie Frauen.

Hypothese: das liegt nicht daran, dass Frauen schlechtere Naturwissenschafter:innen sind als Johns.

Maybe we should honor the women who were real astronauts.

From left to right are Shannon W. Lucid, Margaret Rhea Seddon, Kathryn D. Sullivan, Judith A. Resnik, Anna L. Fisher, and Sally K. Ride. NASA selected all six women as their first female astronaut candidates in January 1978.

Most inflammasome mutations in humans are gain of function, which complicates the question of why we have these molecular machines. @sunnyshinlab.bsky.social et al provide strong evidence that we need inflammasomes to prevent Salmonella infection. A must read! elifesciences.org/articles/90107
Inflammasomes primarily restrict cytosolic Salmonella replication within human macrophages
Analysis of inflammasome responses in human macrophages reveals that inflammatory caspases and pyroptotic factors control Salmonella replication primarily within the cytosol and also within vacuoles.

The loss of TBK1, or both TBK1 and the related kinase IKKε, results in uncontrolled cell death–driven inflammation. We show that TBK1/IKKε prevent premature cell death by limiting the activity of multiple death pathways in myeloid cells. www.science.org/doi/10.1126/...
