Inflammasomes are multiprotein complexes that trigger the activation of caspase-1 and the maturation of IL-1β, which are critical for inflammation and control of pathogen infection. Although the function of inflammasomes in immune response and disease development is well studied, the molecular mechanism by which inflammasomes are activated and assembled remains largely unknown. In this study, w...
The ASC (apoptosis speck-like protein) is a key component of multimeric protein complexes that mediate inflammation and host defence. Comprising a PYD (Pyrin) domain and a CARD (caspase activation and recruitment domain), ASC functions downstream of NLRs (nucleotide-binding domain, leucine-rich repeat-containing receptors) and AIM2 (absent in melanoma 2) through the formation of supramolecular ...
Defence against invading DNA occurs in both mammals and bacteria. Recognition of stray DNA can initiate responses to infection, but may also protect against potentially mutagenic integration of transposons or retrotransposons into the genome. Double-stranded DNA detected in the cytosol of mammalian macrophages can elicit inflammatory cytokines and cell death following assembly of the AIM2 infla...
The innate immune system provides an essential first line of defense against infection. Innate immune cells detect pathogens through several classes of Pattern Recognition Receptors (PRR) allowing rapid response to a broad spectrum of infectious agents. Activated receptors initiate signaling cascades that lead to the production of cytokines, chemokines and type I interferons all of which are vi...
Francisella tularensis (Ft) causes a frequently fatal, acute necrotic pneumonia in humans and animals. Following lethal Ft infection in mice, infiltration of the lungs by predominantly immature myeloid cells and subsequent myeloid cell death drive pathogenesis and host mortality. However, following sub-lethal Ft challenge, more mature myeloid cells are elicited and are protective. In addition, ...
Epstein-Barr virus (EBV), etiologically linked with human B-cell malignancies and nasopharyngeal carcinoma (NPC), establishes three types of latency that facilitate its episomal genome persistence and evasion of host immune responses. The innate inflammasome responses recognize the pathogen-associated molecular patterns which lead into the association of a cytoplasmic sensor such as NLRP3 and A...
