Proud to share our work in collaboration with @labvanni.bsky.social on how malaria parasites solved a membrane cell biology challenge in the RBC using a new class of eukaryotic lipid transporters. Nice data for molecular parasitology and/or general lipid transfer enthusiasts!

Our article is now out in its final form in @natcomms.nature.com. Thankful to reviewers for making our preprint better and of course all contributors and funders. Hopefully my first of many stories understanding the complex membrane cell biology of malaria parasites 🙌 www.nature.com/articles/s41...

The outer membrane of Gram-negative bacteria blocks many antibiotics. Our latest work reveals that L-type pyocins bypass this barrier by inactivating the BAM complex, killing Pseudomonas aeruginosa without entering the cell, providing a new blueprint for beating antibiotic resistance.

A Protein Antibiotic Inhibits the BAM Complex to Kill Without Cell Entry
Many antibiotics are ineffective against Gram-negative pathogens such as Pseudomonas aeruginosa because they cannot penetrate the bacterial outer membrane. Here, we show that protein antibiotics calle...

One for the Apicomplexa peeps: ever wonder how does the IMC grow so fast during progeny formation? Where do all the lipids come from? In our latest work on malaria RBC stages we implicate this monster protein (~6000 residues!) and ER contact sites. Happy+proud to share and keen to hear thoughts!

Our paper is out just in time for #EM_Monday! It is about a specialized neuron-specific ER, called the spine apparatus, which is found close to synapses and has a very peculiar shape. If you think neurons are special, the spine apparatus is their🦄 horn! But how does it form?! doi.org/10.1016/j.cu...
