Amino Acid Substitutions in the Na+/K+-ATPase May Contribute to Salinity Tolerance in Insects

Perla Achi, Victoria Iglesias, Preston Christensen, Rose C. Adrianza, Lanie Bavier, Robert Pena, Cullen McCarthy, Anil Baniya, W. Nate Collison, Simon Cornelis Groen, Adler R. Dillman

This study investigates whether amino acid substitutions in the Na+/K+-ATPase contribute to salt tolerance in insects using gene-edited Drosophila models, finding that some substitutions enhance tolerance while others do not.

Epistasis between Na+/K+-ATPase Substitutions May Influence Salinity Tolerance in Steinernema Entomopathogenic Nematodes

Perla Achi, Cullen McCarthy, Lanie Bavier, Robert Pena, Victoria Iglesias, Preston Christensen, Ahmed Aljidui, Anil Baniya, Connor J. Goldy, Rose C. Adrianza, Suraj Reddy, Simon Cornelis Groen, Adler R. Dillman

This study investigates whether two amino acid substitutions in the Na+/K+-ATPase of Steinernema carpocapsae contribute to its salt tolerance compared to congeners, finding negative epistasis between the substitutions.

A secreted fatty acid- and retinol- binding protein from Heligmosomoides polygyrus suppresses host macrophage polarization

Pakeeza Azizpor, Janice Montoya, Fayez Eyabi, Jose Ramirez, Tara Hill, Robert Pena, Manisha Mishra, Martin J. Boulanger, Adler R. Dillman

This study identifies Hp-FAR-2, a secreted fatty acid- and retinol-binding protein from H. polygyrus, which suppresses macrophage polarization by modulating both M1 and M2 markers, potentially aiding parasite persistence.
