SIK2 orchestrates actin-dependent host response upon Salmonella infection
2021
Significance Through conducting quantitative proteomics upon Salmonella infection, we identified a SIK2 signaling network, implementing the kinase into a so far concealed biological function. Our data exposed SIK2 as a central orchestrator of an actin regulatory network, coordinating the stability of Salmonella-containing vacuole (SCV) and cellular actin assembly, in order to limit the acute phase of the infection. Most strikingly, SIK2 is not exclusively acting locally on actin assembly associated with the SCV but impacts the actin cytoskeleton architecture in its entirety upon Salmonella infection. Our work provides a mechanistic framework for how the actin cytoskeleton is regulated and h…
A New Phylogenetic Framework for the Animal-Adapted
2018
Tuberculosis (TB) affects humans and other animals and is caused by bacteria from the Mycobacterium tuberculosis complex (MTBC). Previous studies have shown that there are at least nine members of the MTBC infecting animals other than humans; these have also been referred to as ecotypes. However, the ecology and the evolution of these animal-adapted MTBC ecotypes are poorly understood. Here we screened 12,886 publicly available MTBC genomes and newly sequenced 17 animal-adapted MTBC strains, gathering a total of 529 genomes of animal-adapted MTBC strains. Phylogenomic and comparative analyses confirm that the animal-adapted MTBC members are paraphyletic with some members more closely relate…
