WebAug 1, 2024 · Cytosolic bacteria benefit from a broad volume to replicate as well as direct access to cytosolic nutrients (Table 1). By contrast, vacuolar residence restricts access to nutrients that do not freely diffuse across phospholipid bilayers [20]. This barrier is overcome by mechanisms allowing the import of nutrients across the vacuolar membrane.
WebJan 24, 2013 · Canonical inflammasomes, such as NLRP3, NLRC4, and AIM2, are cytosolic sensors that detect pathogens or danger signals and activate caspase-1, which leads to secretion of the proinflammatory cytokines interleukin-1β (IL-1β) and IL-18 and pyroptosis, a form of programmed cell death ( 1 ). earlimart middle school caWebDec 12, 2024 · One adaptation common to most cytosolic bacterial pathogens is the ability to coopt the host's actin polymerization machinery in order to generate force for intracellular movement. earlimart ca is in what countyWebNov 21, 2015 · Herein, we report that Caspase-11 is required for innate immunity to cytosolic, but not vacuolar, bacteria.
