Naegleria amoebae seek confinement and crawl persistently through narrow spaces

Katrina Velle, Meera Ramaswamy, Babak Vajdi Hokmabad…·Lillian K. Fritz‐Laylin

This study investigates how Naegleria amoebae navigate narrow spaces and environments, finding they use bleb-based motility and exhibit memory-guided movement that may aid in pathogenesis.

Myosin 2 drives actin contractility in fast-crawling species outside of the amorphean lineage

Sarah L Guest, Katrina Velle, Samantha M Jacques…·Lillian K. Fritz‐Laylin

The paper shows that Myosin 2-driven actin contractility is present in Heterolobosea amoebae, not just Amorphea, and correlates with fast crawling.
