Novel Wolbachia-transinfected Aedes aegypti mosquitoes possess diverse fitness and vector competence phenotypes.

Wolbachia pipientis from Drosophila melanogaster (wMel) is an endosymbiotic bacterium that restricts transmission of human pathogenic flaviviruses and alphaviruses, including dengue, Zika, and chikungunya viruses, when introduced into the mosquito vector Aedes aegypti. To date, wMel-infected Ae. aegypti have been released in field trials in 5 countries to evaluate the effectiveness of this strategy for disease control.

Agp2p, the plasma membrane transregulator of polyamine uptake, regulates the antifungal activities of the plant defensin NaD1 and other cationic peptides.

Cationic antifungal peptides (AFPs) act through a variety of mechanisms but share the common feature of interacting with the fungal cell surface. NaD1, a defensin from Nicotiana alata, has potent antifungal activity against a variety of fungi of both hyphal and yeast morphologies. The mechanism of action of NaD1 occurs via three steps: binding to the fungal cell surface, permeabilization of the plasma membrane, and internalization and interaction with intracellular targets to induce fungal cell death.
