WebMay 27, 2010 · Intracellular bacterial pathogens, such as Listeria monocytogenes, are detected in the cytosol of host immune cells. Induction of this host response is often dependent on microbial secretion systems and, in L. monocytogenes, is dependent on multidrug efflux pumps (MDRs). WebNov 21, 2015 · Herein, we report that Caspase-11 is required for innate immunity to cytosolic, but not vacuolar, bacteria. While Salmonella typhimurium and Legionella pneumophila normally reside in the vacuole ...

WebMechanisms of cytosolic acidification [ edit] Alkaliphiles maintain cytosolic acidification through both passive and active means. In passive acidification, it has been proposed that cell walls contain acidic polymers composed of residues such as galacturonic acid, gluconic acid, glutamic acid, aspartic acid, and phosphoric acid. WebSome bacteria can exit phagosomes and survive and replicate in the cytosolic space. A diverse repertoire of PRRs exist, localized freely in the cytosol or associated with or integrated into cytoplas-mic membranes, to detect these bacteria. These cytosolic PRRs can detect components of the bacterial cell envelope, as well as bacterial nucleic acids.
WebAug 30, 2024 · The cytosol is a more permissive environment than the SCV and supports rapid bacterial growth. The physicochemical conditions encountered by S. Typhimurium within the epithelial cytosol, and the bacterial genes required for cytosolic colonization, remain largely unknown. WebApr 1, 2024 · cGAS and AIM2 are CDSs that are activated in the presence of cytosolic dsDNA and are expressed in various cell types, including immune and tumor cells. The recognition of tumor-derived dsDNA by CDSs in the cytosol of tumor-infiltrating dendritic cells (TIDCs) activates the innate and acquired immunity, thereby enhancing anti-tumor …

WebMar 27, 2009 · The concept is emerging that pathogenic bacteria evolved from environmental species by adapting to an intracellular lifestyle within free-living bacteria-eating protozoans. Consequently, cellular defense mechanisms that are active in animal immune phagocytes may have originated in amoebas ( 1, 2 ).
