Optineurin Deficiency Collapses the Host Endolysosomal Network and Impairs Xenophagy to Accelerate Mycobacterium tuberculosis Growth

Selective autophagy is a host defense mechanism against Mycobacterium tuberculosis (Mtb) that restricts bacterial growth by targeting ubiquitin-coated bacilli for lysosomal degradation via autophagy receptors. Optineurin is a selective autophagy receptor that targets pathogens and modulates immune signaling; however, i...

Substrate Mimicry by Inhibitors of the Mycobacterium tuberculosis 20S Proteasome and Their Activity against Mycobacteria In Vitro and in Macrophages

The remarkable and problematic capacity of Mycobacterium tuberculosis to persist in the host is dependent on a functional 20S proteasome that is structurally and functionally analogous to its mammalian counterpart. It has been proposed that this enzyme is critical for the bacterium’s adaptive response to a variety of...
