What is it about?
The complement system is an important blood immune defence against pathogens like fungi and bacteria. We have shown for the first time, that immune cells called macrophages utilise their own independent complement factors after detecting pathogen signals that allows them to rapidly kill infecting cells.

Why is it important?
Our findings reveal an important immune co-signalling network that occurs within immune cells themselves, when responding to pathogen signals from fungi and bacteria. This research helps answer how these immune cells are efficient responders to diverse pathogen signals. The findings also unlocks therapeutic possibilities to harness complement with drugs to treat infection in at-risk individuals.
