Excited to share our latest work from first author @PatrickWoida. Using a novel surface display platform for expression of split TurboID, we discovered that CYLD is recruited to the Listeria surface via the effector InlC and that it supports cell-to-cell spread

Thrilled to share our latest story from postdoc @sit_brandon! Using a functional genetic screen, he discovered an unexpected way that Rickettsia relies on the host to stabilize the Sca2 surface protein that drives pathogen motility and virulence.

We are excited to kick off the new year with a new publication from the lab!

Acevedo-Sánchez et al. @lamasonlab @MITBiology characterize a novel interkingdom contact site between the ER and a cytosolic bacterial pathogen. They report that these bacteria–ER contacts (BERCs) require the tethering proteins VAPA and VAPB. hubs.la/Q031sGkq0

Editor's Pick: Advancing new models is often tied to technical advances. Lamason et al. add to the toolkit for studying Rickettsia parkeri with new expression and gene silencing approaches. @ASMicrobiology @JBacteriology

More publication alerts from the lab! The final version ( some new data) of our paper using BONCAT to identify novel Rickettsia parkeri secreted effectors is out @NatureComms. nature.com/articles/s41467-0…

Thrilled to share our latest preprint! Most of the Rickettsia secretome is a mystery, and 1st author Allen Sanderlin pioneered the use of BONCAT in this obligate intracellular pathogen to solve this problem, uncovering many new effectors largely unique to this pathogen.

Ever wonder how to engineer Mtb to deliver heterologous cargo to the phagosome? Look no further!!! After trying many strategies over 6 years, we figured out a strategy. (1/10)

New preprint is out detailing the discovery of a novel interaction between Sca4 and clathrin. Great work from authors Cassandra and Brandon @sit_brandon and our collaborators Nam and Kevin from the Macaluso lab!
