Inflammation is characterized by activation of innate immune cells and production of pro-inflammatory cytokines IL-1α, IL-1β, and TNFα. Inflammasomes are intracellular multiprotein complexes expressed in both parenchymal and non-parenchymal cells of the liver that in response to cellular danger signals activate caspase-1, and release IL-1β and IL-18. The importance of inflammasome activation in various forms of liver diseases in relation to liver damage, steatosis, inflammation and fibrosis is discussed in this review. Inflammation is a common element in the pathogenesis of most chronic liver diseases that lead to fibrosis and cirrhosis. Inflammation is characterized by activation of innate immune cells and production of pro-inflammatory cytokines IL-1α, IL-1β, and TNFα. Inflammasomes are intracellular multiprotein complexes expressed in both parenchymal and non-parenchymal cells of the liver that in response to cellular danger signals activate caspase-1, and release IL-1β and IL-18. The importance of inflammasome activation in various forms of liver diseases in relation to liver damage, steatosis, inflammation and fibrosis is discussed in this review. The term “inflammasome”, introduced by Tschopp and colleagues [[1]Martinon F. Burns K. Tschopp J. The inflammasome: a molecular platform triggering activation of inflammatory caspases and processing of pro-IL-beta.Mol Cell. 2002; 10: 417-426Abstract Full Text Full Text PDF PubMed Scopus (1678) Google Scholar] refers to large multiprotein complexes that sense intracellular danger signals via NOD-like receptors (NLR) [[2]Martinon F. Mayor A. Tschopp J. The inflammasomes: guardians of the body.Annu Rev Immunol. 2009; 27: 229-265Crossref PubMed Scopus (994) Google Scholar]. NOD-like receptors, members of the pattern recognition receptor family, contain a C-terminal leucin-rich-repeat (LRR) domain that plays a role in the recognition of ligands, a central NACHT domain that is responsible for the oligomerization and dNTPase activity, and an N-terminal CARD, pyrin (PYD), BIR (baculoviral inhibitory repeat), or acidic transactivation domain. Based on the NACHT domain, three subfamilies of proteins are defined: (a) NODs, (NOD1–5, CIITA), (b) NLRPs or NALPs (NLRP/NALP 1–14), and (c) IPAF (IPAF, NAIP) subfamily [[2]Martinon F. Mayor A. Tschopp J. The inflammasomes: guardians of the body.Annu Rev Immunol. 2009; 27: 229-265Crossref PubMed Scopus (994) Google Scholar] (summarized in Fig. 1). Other classifications, based on the N-terminal effector domain, are also known [[3]Ye Z. Ting J.P. NLR, the nucleotide-binding domain leucine-rich repeat containing gene family.Curr Opin Immunol. 2008; 20: 3-9Crossref PubMed Scopus (113) Google Scholar]. Several, but not all, NLRs play a role in the formation of inflammasomes. With the exception of AIM2, which is a member of the HIN-200 family, the nomenclature of inflammasomes is based on the NOD-like receptor (NLR).Fig. 1Structure of inflammasome and non-inflammasome NLRs and non-NLR inflammasomes.View Large Image Figure ViewerDownload Hi-res image Download (PPT) The sensor, NLR, forms a complex with the effector molecule, pro-caspase-1, with or without the contribution of an adapter molecule, such as the apoptosis-associated speck like CARD-domain containing protein (ASC) [1Martinon F.

Inflammasome activation leads to auto-activation of the 45 kDa inactive pro-caspase-1 precursor into p20 and p10 subunits that form the active caspase-1 [1Martinon F. Burns K. Tschopp J.

The IL-1-like cytokine IL-33 is inactivated after maturation by caspase-1.Proc Natl Acad Sci USA. 2009; 106: 9021-9026Crossref PubMed Scopus (296) Google Scholar]. IL-1β is a pro-inflammatory cytokine, a central regulator of inflammation that binds to the IL-1 receptor (IL-1R) to exert its broad biological effects. IL-1R also recognizes IL-1α and binds IL-1R antagonist (IL-1Ra), the latter inhibiting IL-1R activation [[6]Dinarello C.A.

Inflammasome activation is thought to be a two-step process in which signal 1 (mostly from TLR activation) upregulates inflammasome expression and signal 2 triggers functional inflammasome activation by an inflammasome ligand [2Martinon F.

Schmid-Burgk J. Cavlar T. et al.Inflammasomes: current understanding and open questions.Cell Mol Life Sci. 2011; 68: 765-783Crossref PubMed Scopus (148) Google Scholar]. A recent publication suggests that the priming step is required only for activation of NLRP3 and not other inflammasomes such as NLRC4 or AIM2 [[7]Bauernfeind F. Bartok E. Rieger A. Franchi L.

Cutting edge: reactive oxygen species inhibitors block priming, but not activation, of the NLRP3 inflammasome.J Immunol. 2011; 187: 613-617Crossref PubMed Scopus (187) Google Scholar].

To date, four main prototypes of inflammasomes have been characterized: NLRP1 (NALP1); NLRP3 (NALP3, cryporin); NLRC4 (IPAF) and AIM2 [2Martinon F. Mayor A. Tschopp J.

They have different ligand recognition sites and utilization of adapter molecules but all culminate in caspase-1 activation.Table 1Known activators of inflammasome NLRs. Open table in a new tab NLRP1 (NACHT, LRR, and PYD domains-containing protein 1), the first inflammasome described, can directly interact with caspase-1 through its C-terminal CARD domain, and in humans, the presence of ASC enhances the activity of the complex [[34]Schroder K. Tschopp J. The inflammasomes.Cell. 2010; 140: 821-832Abstract Full Text Full Text PDF PubMed Scopus (1384) Google Scholar]. Murine NLRP1 is unable to bind to ASC because it lacks a functional PYD domain [[34]Schroder K. Tschopp J.

NALP1/NLRP1 genetic variants are associated with Alzheimer disease.Alzheimer Dis Assoc Discord. 2011; (Dec. 6 [Epub ahead of print])Google Scholar]. NLRP1 is activated by the muramyl dipeptide (MDP) and the Bacillus anthracis lethal toxin [8Boyden E.D. Dietrich W.F.

NLRP3 (NACHT, LRR, and PYD domains-containing protein 3, cryoporin) was first described by Hoffman et al. who discovered four single mutations in the NLRP3 gene, in families with familial cold autoinflammatory syndrome and Muckle–Wells syndrome, which lead to increased IL-1β production [[37]Hoffman H.M.

Later, Agostini et al. reported that NLRP3 forms an IL-1β-processing inflammasome complex [[38]Agostini L. Martinon F. Burns K. McDermott M.F. Hawkins P.N. Tschopp J.

To date, NLRP3 is the most fully characterized member of the inflammasome family. It consists of the NOD-like receptor NLRP3, the adaptor molecule ASC, and the effector molecule pro-caspase-1. Since NLRP3 does not contain a CARD domain, the presence of the adaptor molecule is necessary for the complex formation [[34]Schroder K. Tschopp J. The inflammasomes.Cell. 2010; 140: 821-832Abstract Full Text Full Text PDF PubMed Scopus (1384) Google Scholar].

Consistent with the role of lysosomal damage in inflammasome activation, the role of a lysosomal protease, cathepsin B, has been implicated in certain forms of NLRP3 activation [4Bauernfeind F. Ablasser A. Bartok E. Kim S. Schmid-Burgk J.

NLRP3 inflammasome activation: the convergence of multiple signaling pathways on ROS production?.Nat Rev Immunol. 2010; 10: 210-215Crossref PubMed Scopus (437) Google Scholar]. Third, some studies suggest that reactive oxygen species (ROS) contribute to inflammasome activation. This is based on the observation that inhibitors or scavengers that block mitochondrial ROS or NADPH oxidase suppress inflammasome activation [4Bauernfeind F. Ablasser A. Bartok E. Kim S.

ROS induction may represent a common pathway from different cellular insults. For example, large particles [[43]Fubini B. Hubbard A.

ROS-dependent release of thioredoxin-interacting protein (TXNIP) from thioredoxin and direct interaction between TXNIP and NLRP3 have been described [[45]Zhou R. Tardivel A. Thorens B. Choi I. Tschopp J. Thioredoxin-interacting protein links oxidative stress to inflammasome activation.Nat Immunol. 2010; 11: 136-140Crossref PubMed Scopus (660) Google Scholar]. However, ROS production does not always result in inflammasome activation [4Bauernfeind F. Ablasser A. Bartok E. Kim S. Schmid-Burgk J.
