    BAFF-R, a newly identified TNF receptor that specifically interacts with BAFF (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-08-18
    Description: B cell homeostasis has been shown to critically depend on BAFF, the B cell activation factor from the tumor necrosis factor (TNF) family. Although BAFF is already known to bind two receptors, BCMA and TACI, we have identified a third receptor for BAFF that we have termed BAFF-R. BAFF-R binding appears to be highly specific for BAFF, suggesting a unique role for this ligand-receptor interaction. Consistent with this, the BAFF-R locus is disrupted in A/WySnJ mice, which display a B cell phenotype qualitatively similar to that of the BAFF-deficient mice. Thus, BAFF-R appears to be the principal receptor for BAFF-mediated mature B cell survival.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Thompson, J S -- Bixler, S A -- Qian, F -- Vora, K -- Scott, M L -- Cachero, T G -- Hession, C -- Schneider, P -- Sizing, I D -- Mullen, C -- Strauch, K -- Zafari, M -- Benjamin, C D -- Tschopp, J -- Browning, J L -- Ambrose, C -- New York, N.Y. -- Science. 2001 Sep 14;293(5537):2108-11.

    Syk kinase signalling couples to the Nlrp3 inflammasome for anti-fungal host defence (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-04-03
    Description: Fungal infections represent a serious threat, particularly in immunocompromised patients. Interleukin-1beta (IL-1beta) is a key pro-inflammatory factor in innate antifungal immunity. The mechanism by which the mammalian immune system regulates IL-1beta production after fungal recognition is unclear. Two signals are generally required for IL-1beta production: an NF-kappaB-dependent signal that induces the synthesis of pro-IL-1beta (p35), and a second signal that triggers proteolytic pro-IL-1beta processing to produce bioactive IL-1beta (p17) via Caspase-1-containing multiprotein complexes called inflammasomes. Here we demonstrate that the tyrosine kinase Syk, operating downstream of several immunoreceptor tyrosine-based activation motif (ITAM)-coupled fungal pattern recognition receptors, controls both pro-IL-1beta synthesis and inflammasome activation after cell stimulation with Candida albicans. Whereas Syk signalling for pro-IL-1beta synthesis selectively uses the Card9 pathway, inflammasome activation by the fungus involves reactive oxygen species production and potassium efflux. Genetic deletion or pharmalogical inhibition of Syk selectively abrogated inflammasome activation by C. albicans but not by inflammasome activators such as Salmonella typhimurium or the bacterial toxin nigericin. Nlrp3 (also known as NALP3) was identified as the critical NOD-like receptor family member that transduces the fungal recognition signal to the inflammasome adaptor Asc (Pycard) for Caspase-1 (Casp1) activation and pro-IL-1beta processing. Consistent with an essential role for Nlrp3 inflammasomes in antifungal immunity, we show that Nlrp3-deficient mice are hypersusceptible to Candida albicans infection. Thus, our results demonstrate the molecular basis for IL-1beta production after fungal infection and identify a crucial function for the Nlrp3 inflammasome in mammalian host defence in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gross, Olaf -- Poeck, Hendrik -- Bscheider, Michael -- Dostert, Catherine -- Hannesschlager, Nicole -- Endres, Stefan -- Hartmann, Gunther -- Tardivel, Aubry -- Schweighoffer, Edina -- Tybulewicz, Victor -- Mocsai, Attila -- Tschopp, Jurg -- Ruland, Jurgen -- MC_U117527252/Medical Research Council/United Kingdom -- England -- Nature. 2009 May 21;459(7245):433-6. doi: 10.1038/nature07965.

    The PIDDosome, a protein complex implicated in activation of caspase-2 in response to genotoxic stress (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-04-10
    Description: Apoptosis is triggered by activation of initiator caspases upon complex-mediated clustering of the inactive zymogen, as occurs in the caspase-9-activating apoptosome complex. Likewise, caspase-2, which is involved in stress-induced apoptosis, is recruited into a large protein complex, the molecular composition of which remains elusive. We show that activation of caspase-2 occurs in a complex that contains the death domain-containing protein PIDD, whose expression is induced by p53, and the adaptor protein RAIDD. Increased PIDD expression resulted in spontaneous activation of caspase-2 and sensitization to apoptosis by genotoxic stimuli. Because PIDD functions in p53-mediated apoptosis, the complex assembled by PIDD and caspase-2 is likely to regulate apoptosis induced by genotoxins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tinel, Antoine -- Tschopp, Jurg -- New York, N.Y. -- Science. 2004 May 7;304(5672):843-6.

    A role for mitochondria in NLRP3 inflammasome activation (2010)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2010-12-03
    Description: An inflammatory response initiated by the NLRP3 inflammasome is triggered by a variety of situations of host 'danger', including infection and metabolic dysregulation. Previous studies suggested that NLRP3 inflammasome activity is negatively regulated by autophagy and positively regulated by reactive oxygen species (ROS) derived from an uncharacterized organelle. Here we show that mitophagy/autophagy blockade leads to the accumulation of damaged, ROS-generating mitochondria, and this in turn activates the NLRP3 inflammasome. Resting NLRP3 localizes to endoplasmic reticulum structures, whereas on inflammasome activation both NLRP3 and its adaptor ASC redistribute to the perinuclear space where they co-localize with endoplasmic reticulum and mitochondria organelle clusters. Notably, both ROS generation and inflammasome activation are suppressed when mitochondrial activity is dysregulated by inhibition of the voltage-dependent anion channel. This indicates that NLRP3 inflammasome senses mitochondrial dysfunction and may explain the frequent association of mitochondrial damage with inflammatory diseases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zhou, Rongbin -- Yazdi, Amir S -- Menu, Philippe -- Tschopp, Jurg -- England -- Nature. 2011 Jan 13;469(7329):221-5. doi: 10.1038/nature09663.

    The NLRP3 inflammasome: a sensor for metabolic danger? (2010)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2010-01-16
    Description: Interleukin-1beta (IL-1beta), reactive oxygen species (ROS), and thioredoxin-interacting protein (TXNIP) are all implicated in the pathogenesis of type 2 diabetes mellitus (T2DM). Here we review mechanisms directing IL-1beta production and its pathogenic role in islet dysfunction during chronic hyperglycemia. In doing so, we integrate previously disparate disease-driving mechanisms for IL-1beta, ROS, and TXNIP in T2DM into one unifying model in which the NLRP3 inflammasome plays a central role. The NLRP3 inflammasome also drives IL-1beta maturation and secretion in another disease of metabolic dysregulation, gout. Thus, we propose that the NLRP3 inflammasome contributes to the pathogenesis of T2DM and gout by functioning as a sensor for metabolic stress.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schroder, Kate -- Zhou, Rongbin -- Tschopp, Jurg -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):296-300. doi: 10.1126/science.1184003.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry, University of Lausanne, CH-1066 Epalinges, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20075245" target="_blank"〉PubMed〈/a〉
