Interested in #mosquito immunity, blood feeding & vector competence? @georgesaman.bsky.social & I have a new review in @frontiersin.bsky.social on how the blood meal, microbiota & endocrine signals shape immune function and pathogen transmission. 🦟 #VectorBiology www.frontiersin.org/journals/imm...

Pleased to share our recent work in collaboration with the @perrimonlab.bsky.social in which we perform the first genome-wide CRISPR knockout screen in Anopheles to examine essential fitness genes and genes associated with clodronate liposome function www.nature.com/articles/s41...

A genome-wide CRISPR screen in Anopheles mosquito cells identifies fitness and immune cell function-related genes

Nature Communications - Mosquitoes are major vectors for the transmission of many serious pathogens. This study uses genome-wide CRISPR screens in the mosquito, Anopheles gambiae, to reveal new...

To the insect folks — does anyone have experience with the World Precision Instruments injectors? Our new Nanoject III stopped working after the third use, and we’re now exploring other options, such as this one www.wpi-europe.com/products/ani... If you know anything about it, please drop a comment!

🦟 Can we "pasteurize" mosquitoes to stop dengue & Zika? Sarah Merkling @merklinglab.bsky.social uses AI + CRISPR to analyze stomach cells and understand why some mosquitoes spread viruses while others don't. Goal: Make disease-carrying mosquitoes harmless. #Zika #Dengue

Sarah Merkling wants to "pasteurize" mosquitoes!

At the Institut Pasteur, Sarah Merkling's research focuses on a topic that is still largely unknown: interactions between mosquitoes and viruses. She boldly devises novel strategies based on state-of-...

Excited to announce the final version of the Mosquito Cell Atlas is out now in @cellpress.bsky.social!! 🦟🩸 There is SO much left to find & investigate in this dataset (& the rich biology of the Aedes aegypti mosquito)! We hope this helps scientists in many fields! www.cell.com/cell/fulltex...

It was about time to leave the old platform and join this one! Excited to connect with old and new friends here 🧬✨ #vectorbiology #mosquitoes

Our new study is out in Cell Reports! We show that the DNA repair pathway ATM-γH2Av is repurposed in the gut during infection, even without DNA breaks. Pathogens, not microbiota, trigger it via NOX to clear damaged cells and drive stem cell regeneration. www.cell.com/cell-reports...

Infectious bacteria, but not the microbiota, induce a NOX-ATM-cytokine pathway that controls epithelial turnover

Nagy et al. identify a NOX-ATM-cytokine signaling axis in the Drosophila gut that is activated by infection independently of DNA damage. This pathway promotes enterocyte loss, cytokine production, and...

Celebrating the holiday weekend with another bang! Our work describing roles of TNF signaling on mosquito immune cell function and in limiting malaria parasite infection is now published. Big shout out to @georgesaman.bsky.social and others for their contributions! journals.plos.org/plospathogen...

TNF signaling mediates cellular immune function and promotes malaria parasite killing in the mosquito Anopheles gambiae

Author summary Mosquito innate immunity is a major determinant of vector competence with significant implications in malaria transmission. During infection with the Plasmodium parasite, mosquitoes mou...
