The Emerging Role of 3-Hydroxyanthranilic Acid on C. elegans Aging Immune Function

L. S. Espejo, D. D. DeNicola, L. M. Chang, V. D. Silbar, A. E. Haskins, A. B. Antenor, J. r. Balsa, S. Freitas, S. Hamming, B. Hull, H. Dang, R. Castro-Portuguez, G. L. Sutphin

This paper investigates how 3HAA and haao-1 inhibition affect C. elegans immune function and aging, finding that 3HAA improves immune function and acts as an antimicrobial against gram-negative bacteria.

SICKO: Systematic Imaging of Caenorhabditis Killing Organisms

L. S. Espejo, S. Freitas, V. Hofschneider, L. Chang, A. Antenor, J. Balsa, A. Haskins, D. DeNicola, H. Dang, S. Hamming, D. Kelser, G. L. Sutphin

SICKO enables longitudinal tracking of microbial colonization and host survival in C. elegans, revealing that gut colonization by E. coli or Pseudomonas aeruginosa shortens lifespan and that pmk-1-deficient animals are more susceptible.

Facultative parthenogenesis: a transient state in transitions between sex and obligate asexuality in stick insects?

C. Larose, G. Lavanchy, S. Freitas, D. J. Parker, T. Schwander

The paper identifies and characterizes facultative parthenogenetic populations in stick insects, showing they lose heterozygosity and may transition to obligate parthenogenesis through increased frequency.
