- F-actin flashes on phagosomes mechanically deform contents for efficient digestion in macrophages
Summary: We find that internalized particles are mechanically deformed in macrophages, suggesting that the process of phagocytosis also employs a ‘chewing’ step to help destroy unwanted targets in macrophages.
- Complement-mediated ‘bystander’ damage initiates host NLRP3 inflammasome activation
Summary: This paper describes a new mechanism whereby the terminal part of complement (the membrane attack complex) can trigger host NLRP3 inflammasome activation.
