Linking immunity and nutrition: Vital DNA extracellular trap formation in Dictyostelium discoideum reveals an ancestral strategy for microbial management

Antonia Ramos, Paulina Aguilera‐Cortés, Sebastian Farias, Ian Pérez, Viviana Barros, Boris Riveros, Tabata Soto, Miguel Ángel Ibáñez-Hernández, Camilo Berríos-Pastén, Diego Rojas, Andrés E. Marcoleta, Francisco P. Chávez

This study shows that Dictyostelium discoideum uses mitochondrial DNA-based extracellular traps for microbial management, revealing an ancestral function of ETosis outside classical immunity.

Expanding the toolbox for hypervirulent Klebsiella pneumoniae using the social amoeba Dictyostelium discoideum as a virulence biosensor

Ian Pérez, Matías Gálvez-Silva, Diego Rojas, Antonia Ramos, Miranda Bravo, Yahua Chen, Yunn‐Hwen Gan, Francisco P. Chávez, Andrés E. Marcoleta

This paper introduces a biosensing approach using Dictyostelium discoideum to detect hypervirulent Klebsiella pneumoniae strains through measurable host behavioral responses.

Inhibition of cytosolic DNA sensing and transposon activity safeguards pluripotency

Ferran Garcia-Llagostera, Audrey L. K. Putman, Alexandros Choromidis, Bryony J. Leeke, Klaudia Stanik, Antonia Ramos, Benjamin Moyon, Jesús Gil, Alexis R. Barr, Michelle Percharde

The paper identifies mechanisms that prevent innate immune activation by TE-derived cytosolic DNA, preserving pluripotency in ESCs.
