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.

New paper alert! I’m very excited to share our paper published in @embojournal.org! @pdc-lab.bsky.social @yaleneuro.bsky.social

Rodriguez Salazar, @caglaeroglu.bsky.social et al. @dukehealth.bsky.social show that Drp1-mediated mitochondrial fission is necessary for peripheral #astrocyte process formation. Loss of Drp1 induces astrocyte reactivity & disrupts cortical astrocyte organization rupress.org/jcb/article/...

@anbangdai.bsky.social et al. @pdc-lab.bsky.social report the localization of BLTP2 in different human cell types & reveal binding partners that mediate its tethering to the PM & to PM-connected structures including certain #endosomes & #macropinosomes undergoing fusion rupress.org/jcb/article/...

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...
