of the social amoebae Dictyostelium discoideum lead to an unusual resilience to protein aggregation» (2014)
This is a slug made up
of social amoebae.
When confronted with invading bacteria, cells within the multicellular slug stage
of the social amoeba (Dictyostelium discoideum) immediately seek to kill them, casting extracellular traps made of DNA nets studded with antimicrobial granules.
