The Salmonella inner membrane is a coordinated adaptive network, and this view can help identify antibacterial targets that weaken bacterial adaptation rather than simply blocking one isolated protein.
The extent to which chaperones are universally required for effector secretion is evaluated, through analysis of the conservation of chaperone sequence and structure, to discuss how these proteins interact with and support the secretion of diverse substrates.

The data establish OMVs as a robust new platform for structure-activity analysis of OM proteins in situ, offer new insights about the complexity of the bacterial OM, and reveal additional functional aspects of OMVs as key ancillary units of bacterial infection.

The T2SS is a fascinatingly complex “machine” whose contributing parts can vary and whose ability to recognize substrates is primarily conformational, involving spatially separated elements that interact with the T2SS apparatus through transient, multivalent interactions rather than a single dedicated binding motif.

This review synthesizes current knowledge of Mtb Mce systems with an emphasis on transporter organization, regulatory mechanisms, functional specialization, and biological significance during infection and highlights the key unresolved questions that should guide the next phase of the field.
Mycobacteria possess a complex double-membrane cell envelope critical for survival and pathogenesis. Proper assembly of this architecture requires the biosynthesis and transport of major components, including arabinogalactan (AG) polysaccharides and mycolic acids (MAs), but how these processes are effectively coordinat...
Current knowledge on T9SS architecture and function is summarized, the embedded gliding machinery is described, and conceptual advances and open questions regarding the mechanisms, dynamics, and ecological implications of this unique system are highlighted.
