Happy to share our recent story on the Type VII secretion system. Here were present new insights into the regulation of secretion mediated by the central pore. Thanks to all authors involved in the work. 🙂

In vivo antimicrobial activity of engineered mesoporous silica nanoparticles targeting intracellular mycobacteria - Nature Communications
Current treatment options for Mycobacterium marinum infections are extensive and challenging. In this work, authors explore the potential of functionalized mesoporous silica nanoparticles as a carrier for delivery of drugs against M. marinum.

Trehalose polyphleates participate in Mycobacterium abscessus fitness and pathogenesis - PubMed
Mycobacteria produce a large repertoire of surface-exposed lipids with major biological functions. Among these lipids, trehalose polyphleates (TPPs) are instrumental in the infection of <i>Mycobacterium abscessus</i> by the therapeutic phage BPs. However, while the biosynthesis and transport of TPPs …

Together with Abdallah and Qingtian we just published this pan-genome analysis for M. marinum. I think it is a nice catalog, but standing out for me was the variation in the cpnT gene and the fact that ESX-2 is present in the majority of the M. marinum strains, just not in the type strain M...
