Similarly, activation of the NLRP1B and NLRP3 inflammasomes depends on low K+ concentrations in intracellular compartments79, and a low K+ concentration promotes the assembly of the ASC speck6. PubMed:23702978
They include the adaptor protein, ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain), which is an essential component of the NLRP1, NLRP2 and NLRP3 inflammasomes, but not of the more complex NLRC4 inflammasome (Martinon et al., 2009; Minkiewicz et al., 2013; Schroder and Tschopp, 2010) PubMed:24561250
ATP, a danger-associated molecular pattern that is released from damaged cells after brain injury, activates the NLRP2 inflammasome, which consists of the NLRP2 receptor, ASC and caspase-1, in human astrocytes (Minkiewicz et al., 2013) PubMed:24561250
In addition, NLRC4 and ASC levels are upregulated in the brains of AD patients (Liu and Chan, 2014), suggesting a possible role of the NLRC4 inflammasome in AD pathogenesis PubMed:24561250
Using its CARD, ASC brings monomers of procaspase 1 into close proximity, which initiates caspase 1 self- cleavage and the formation of the active heterotetrameric caspase 1. PubMed:23702978

Under certain but not all conditions ASC (Martinon et al., 2009) or Naip5 (NLR family, apoptosis inhibitory protein 5) (Lightfield et al., 2011) is required for the activity of the NLRC4 inflammasome PubMed:24561250
The adaptor protein ASC is important for the activation of NLRC4 inflammasome in astrocytes, while Naip 5 is not (Liu and Chan, 2014) PubMed:24561250
Recently we identify that palmitate activates the NLRC4 inflammasome in primary astrocytes to release IL-1β, and ASC participates in the activation of the NLRC4 inflammasome (Liu and Chan, 2014) PubMed:24561250
ASC neutralization reduces the upregulation in IL-18 and IL-1β levels (de Rivero Vaccari et al., 2008) PubMed:24561250
