Participation of c-FLIP in NLRP3 and AIM2 inflammasome activation
No full textCellular FLICE-inhibitory protein (c-FLIP) is an inhibitor of caspase-8 and is required for macrophage survival. Recent studies have revealed a selective role of caspase-8 in noncanonical IL-1 beta production that is independent of caspase-1 or inflammasome. Here we demonstrated that c-FLIPL is an unexpected contributor to canonical inflammasome activation for the generation of caspase-1 and active IL-1 beta. Hemizygotic deletion of c-FLIP impaired ATP-and monosodium uric acid (MSU)-induced IL-1 beta production in macrophages primed through Toll-like receptors (TLRs). Decreased IL-1 beta expression was attributed to a reduced activation of caspase-1 in c-FLIP hemizygotic cells. In contrast, the production of TNF-alpha was not affected by downregulation in c-FLIP. c-FLIPL interacted with NLRP3 or procaspase-1. c-FLIP is required for the full NLRP3 inflammasome assembly and NLRP3 mitochondrial localization, and c-FLIP is associated with NLRP3 inflammasome. c-FLIP downregulation also reduced AIM2 inflammasome activation. In contrast, c-FLIP inhibited SMAC mimetic-, FasL-, or Dectin-1-induced IL-1 beta generation that is caspase-8-mediated. Our results demonstrate a prominent role of c-FLIPL in the optimal activation of the NLRP3 and AIM2 inflammasomes, and suggest that c-FLIP could be a valid target for treatment of inflammatory diseases caused by over-activation of inflammasomes
Digital-twin-based active input refinement for insertion loss estimation and QoT optimization in C and C + L networks
No full textQuality of transmission (QoT) prediction is a fundamental function in optical networks. It is typically embedded within a digital twin and used for operational tasks, including service establishment, service rerouting, and (per-channel or per-amplifier) power management to optimize the working point of services and hence to maximize their capacity. Inaccuracy in QoT prediction results in additional, unwanted design margins. A key contributor to QoT inaccuracy is the uncertain knowledge of fiber insertion loss, e.g., the attenuation due to connector losses at the beginning or at the end of each fiber span, as such loss cannot be directly monitored. Indeed, insertion losses drive the choice of the launch power in fiber spans, which in turn drive key physical effects, including the Kerr and stimulated Raman scattering (SRS) effects, which affect services’ QoT. It is thus important to estimate (and detect possibly anomalous) fiber insertion losses at each span. We thereby propose a novel active input refinement (AIR) technique using active probing to estimate insertion losses in C and C
L systems. Here, active probing consists of adjusting amplifier gains span by span to slightly alter SRS. The amount of adjustment must be sufficient to be measurable (such that insertion losses can be inferred from the measures) but small enough to have a negligible impact on running services in a live network. The method is validated by simulations on a European network with 30 optical multiplex sections (OMSs) in C and C
L configurations and by lab experiments on a C-band network, demonstrating that AIR significantly improves insertion loss estimation, network QoT optimization, and QoT prediction compared with other state-of-the-art monitoring techniques. This work underscores the critical role of accurate estimation of QoT inputs in enhancing optical network performance

No full textElectrochemical Detection of High-Sensitivity C-Reactive Protein Based on Biomimic Design of Electroactive Nanoassembly Multilayers
No full textIn this study, the gold electrode was modified with a ferrocene-terminated alkanethiol and phospholipid complex layer, which is designed and fabricated to serve as a C-reactive protein sensor using electrochemical determination. The scope of this research is to know whether a ferrocene-terminated self-assembled monolayer and hydrogenated phosphocholine hybrid bilayer could be used to perform C-reactive protein detection or not. After a series of experiments, the result shows that mixed electroactive SAM can facilitate electrons transferring from the solution to the electrode. And after coating phospholipids, this phenomenon seems to be hindered from the electrode. But this provoked small electrical signal of the recognition layer still allows for further usage. According to the result, it can be used to measure C-reactive protein and its electrochemical property and the changes of the electrode's electron transfer ability are characterized by cyclic voltammetry. This study demonstrates self-assembled ferrocene-terminated alkanethiol and phospholipid complex structure has potential as a C-reactive protein sensor and is stable to detect in the aqueous phase.補正完

Tumor necrosis factor-related apoptosis-inducing ligand-induced death-inducing signaling complex and its modulation by c-FLIP and PED/PEA-15 in glioma cells.
No full textTumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can trigger apoptosis in some tumor cells but not other tumor cells. To explore the signal transduction events in TRAIL-triggered apoptosis and its modulation in nontransfected tumor cells, we analyzed TRAIL-induced death-inducing signaling complex (DISC) in TRAIL-sensitive and -resistant glioma cells. Caspase-8 and caspase-10 were recruited to the DISC, where they were proteolytically activated to initiate apoptosis in TRAIL-sensitive glioma cells. Caspase-8 and caspase-10 were also recruited to the DISC in TRAIL-resistant cells, but their further activation was inhibited by two antiapoptotic proteins termed cellular Fas-associated death domain-like interleukin-1beta-converting enzyme-inhibitory protein (c-FLIP) and phosphoprotein enriched in diabetes/phosphoprotein enriched in astrocytes-15kDa (PED/PEA-15). Both long and short forms of c-FLIP were recruited to the DISC, where the long form c-FLIP was cleaved to produce intermediate fragments. Of the three isoforms of PED/PEA-15 proteins, only the doubly phosphorylated form was expressed and recruited to the DISC in TRAIL-resistant cells, indicating that the phosphorylation status of PED/PEA-15 determines its recruitment in the cells. Treatment with calcium/calmodulin-dependent protein kinase inhibitor rescued TRAIL sensitivity in TRAIL-resistant cells, providing a potential new approach to sensitize the cells to TRAIL-induced apoptosis

Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
