Figure Lengend Snippet: Model of danger signals activation of the NALP3 inflammasome. Tissue injury leads to the formation and release of danger signals such as ATP or uric acid crystals that are recognized by the innate immune system. A number of these signals mediate a potassium efflux or other secondary intracellular danger signals that are required for NALP3 inflammasome activation [ , ]. NALP3 inflammasome then oligomerizes to recruit the adaptor ASC and caspase-1 . Activation of caspase-1 results in the processing and maturation of pro IL-1 β into its biologically active form, active IL-1 β [ , ]. Active IL-1 β will then trigger the IL-1 β receptor, leading to the activation of multiple cytokines involved in the inflammation cascade .

Figure Lengend Snippet: Cellular distribution of NALP3 inflammasome components and IL-1 β in the ischemic penumbra zone of cerebral cortex. Sections were triple-stained for NALP3, ASC, caspase-1 and IL-1 β (red), NeuN (green), and nucleus (blue). In tMCAO group, the neuronal karyopyknosis and chromatin margination could be observed and there was a small amount of neutrophils in marginal zone of infarction. In the normal brain (Sham), caspase-1 and NALP3 were mainly present in the nucleus of neurons whereas IL-1 β was mainly localized in the cytoplasm. ASC was present in both the nucleus and cytoplasm. After tMCAO, NALP3 and caspase-1 were redistributed predominantly to the cytoplasm, while ASC and IL-1 β location remained unchanged.

Figure Lengend Snippet: Immunohistochemical staining of NALP3, ASC, caspase-1, and IL-1 β in the cerebral cortex at 24 h after ischemia (400x magnification). As compared with tMACO and Vehicle groups, the expression of NALP3, caspase-1, and IL-1 β was significantly reduced in CHR-H and CHR-M groups, but the expression of ASC remained unchanged.
