Inflammasomes are multiprotein complexes that induce downstream immune responses to specific pathogens, environmental stimuli, and host cell damage. Components of specific viruses activate different inflammasomes; for example, the influenza A virus M2 protein and encephalomyocarditis virus (EMCV) 2B protein activate the nucleotide-binding oligomerization domain (NOD)-like receptor family pyrin domain (PYD)-containing 3 (NLRP3) inflammasome, whereas viral double-stranded RNA (dsRNA) activates the retinoic acid inducible gene-I (RIG-I) inflammasome. Once activated in response to viral infection, inflammasomes induce the activation of caspases and the release of mature forms of interleukin-1β (IL-1β) and IL-18. Here we review the association between viral infection and inflammasome activation. Identifying the mechanisms underlying virus-induced inflammasome activation is important if we are to develop novel therapeutic strategies to target viruses.

UI MeSH Term Description Entries
D011971 Receptors, Immunologic Cell surface molecules on cells of the immune system that specifically bind surface molecules or messenger molecules and trigger changes in the behavior of cells. Although these receptors were first identified in the immune system, many have important functions elsewhere. Immunologic Receptors,Immunologic Receptor,Immunological Receptors,Receptor, Immunologic,Receptors, Immunological
D002352 Carrier Proteins Proteins that bind or transport specific substances in the blood, within the cell, or across cell membranes. Binding Proteins,Carrier Protein,Transport Protein,Transport Proteins,Binding Protein,Protein, Carrier,Proteins, Carrier
D003598 Cytoskeletal Proteins Major constituent of the cytoskeleton found in the cytoplasm of eukaryotic cells. They form a flexible framework for the cell, provide attachment points for organelles and formed bodies, and make communication between parts of the cell possible. Proteins, Cytoskeletal
D004268 DNA-Binding Proteins Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases.

D000071198 Pyrin A tripartite motif protein that consists of an N-terminal pyrin domain, a central coiled-coil region and B-box type ZINC FINGER, and C-terminal regions that mediate homotrimerization and interactions with other proteins (the B30.2/SPRY DOMAIN). It is expressed primarily by mature GRANULOCYTES and associates with the cytoskeleton in the perinuclear area as well as AUTOPHAGOSOMES, where it co-ordinates the assembly of AUTOPHAGY-RELATED PROTEINS and degradation of INFLAMMASOME components. It functions in INNATE IMMUNITY and INFLAMMATION; mutations in the Pyrin protein (MEFV) gene are associated with FAMILIAL MEDITERRANEAN FEVER. MEFV Protein,Marenostrin,Mediterranean Fever Protein,TRIM20 Protein
D000071199 NLR Family, Pyrin Domain-Containing 3 Protein An NLR protein that contains an N-terminal PYRIN DOMAIN and ATP-binding site and 9 C-terminal LEUCINE-rich repeats; it is expressed primarily by MACROPHAGES. It is a core component of the INFLAMMASOME and directs its assembly in response to pathogen infection and damage-associated stimuli. Mutations in the NLRP3 gene are associated with FAMILIAL COLD AUTOINFLAMMATORY SYNDROME. Cold Autoinflammatory Syndrome 1 Protein,NACHT, LRR and PYD Domains-Containing Protein 3,NLRP3 Protein,NACHT, LRR and PYD Domains Containing Protein 3,NLR Family, Pyrin Domain Containing 3 Protein
D000071457 DEAD Box Protein 58 A DEAD-box RNA helicase that contains an N-terminal DEATH-LIKE DOMAIN, AAA+ ATPase domain, and C-terminal RNA HELICASE activity. It functions as an innate immune receptor through its recognition of viral nucleic acids. It also induces the expression of INTERFERON TYPE I and proinflammatory CYTOKINES. Its ligands include: 5'-triphosphorylated SINGLE-STRANDED RNA, DOUBLE-STRANDED RNA (dsRNA), and short dsRNA (less than 1 kb in length). DEAD (Asp-Glu-Ala-Asp) Box Polypeptide 58,Probable ATP-Dependent RNA Helicase DDX58,RIG-I-like Receptor 1,Probable ATP Dependent RNA Helicase DDX58,RIG I like Receptor 1

D012330 RNA, Double-Stranded RNA consisting of two strands as opposed to the more prevalent single-stranded RNA. Most of the double-stranded segments are formed from transcription of DNA by intramolecular base-pairing of inverted complementary sequences separated by a single-stranded loop. Some double-stranded segments of RNA are normal in all organisms. Double-Stranded RNA,Double Stranded RNA,RNA, Double Stranded
