Spreading the Fire: Why is Pyroptotic Cell Death Contagious?
The word ¨pyroptosis¨ can be understood as ¨fiery falling¨, which describes the bursting of pro-inflammatory signals from the dying cell. Our observations indicate that pyroptosis also ¨spreads like wildfire¨ and once a cell dies via pyroptotic cell death, neighbouring cells are more prone to die as…

Researchers tackle antibiotic-resistant bacteria
When a bacterium becomes more resistant to one antibiotic, it sometimes becomes more sensitive to another. To better understand this interaction, researchers from the Leiden Institute of Biology (IBL) and the Leiden Academic Center for Drug Research (LACDR) under supervision of Daniel Rozen and Coen…

ERC-subsidie om uit te zoeken hoe kinderen luchtweginfecties te lijf gaan
De crèche en het klaslokaal zijn misschien wel de meest gunstige plekken voor ziekteverwekkers. Toch is er relatief weinig bekend over hoe kinderen reageren op virussen en bacteriën en hoe het komt dat sommige kinderen veel beter beschermd zijn dan anderen. Simon Jochems, onderzoeker aan het Leids Universitair…

Resistance and Revolt in Egypt and Babylonia: The Persian Empire (539-330 BC) in the Eyes of its Rebels
The Persian Empire (539-330 BCE) was the first world empire in history. At its height, it united a territory stretching from present-day India to Libya - and it would take 2,000 years before significantly larger empires emerged in early modern Eurasia. Its size and power was revered by some, feared…
