    Atmospheric particulate matter aggravates CNS demyelination through involvement of TLR-4/NF-kB signaling and microglial activation

    Bing Han, Xing Li ... Yuan Zhang
    An atmospheric trigger, the respirable particulate matter boost microglia pathogenic activities in the context of CNS demyelination by activating TLR-4/NF-kB signaling axis in animal models of immune- and toxicity-induced demyelination, as well as myelinogenesis during postnatal development.

    Structures of NF-κB p52 homodimer-DNA complexes rationalize binding mechanisms and transcription activation

    Wenfei Pan, Vladimir A Meshcheryakov ... Vivien Ya-Fan Wang
    Structural and biophysical characterization of NF-κB p52 in complex with closely related DNAs reveals the dynamic states of central base pair(s) have a strong influence on transcriptional activity of p52.

    Age-related islet inflammation marks the proliferative decline of pancreatic beta-cells in zebrafish

    Sharan Janjuha, Sumeet Pal Singh ... Nikolay Ninov
    During aging, the pancreatic endocrine islets undergo chronic inflammation, which is associated with a reduced capacity for self-renewal of the insulin-producing beta-cells in zebrafish.

    Stimulus-selective crosstalk via the NF-κB signaling system reinforces innate immune response to alleviate gut infection

    Balaji Banoth, Budhaditya Chatterjee ... Soumen Basak
    The integration of signals via the pleiotropic NF-kappaB (NF-κB) system enables microenvironmental cues to tune cellular responses to pathogenic substances.

    Inflammatory osteolysis is regulated by site-specific ISGylation of the scaffold protein NEMO

    Naga Suresh Adapala, Gaurav Swarnkar ... Yousef Abu-Amer
    Site-specific modification of NEMO facilitates RANKL signal specificity in myeloid progenitors and serves as a potential target to modulate inflammatory osteolysis through ISG15-dependent autophagy.

    Hepatic NF-kB-inducing kinase (NIK) suppresses mouse liver regeneration in acute and chronic liver diseases

    Yi Xiong, Adriana Souza Torsoni ... Liangyou Rui
    Genetic mouse models show that hepatic NIK and IKKα inhibit hepatocyte proliferation and liver regeneration in part by inhibiting the JAK2/STAT3 pathway.

    TRAF2 regulates TNF and NF-κB signalling to suppress apoptosis and skin inflammation independently of Sphingosine kinase 1

    Nima Etemadi, Michael Chopin ... John Silke
    Intrinsic defects in keratinocytes can cause skin inflammation through excessive cell death and production of inflammatory molecules.

    Caspase-8 contributes to angiogenesis and chemotherapy resistance in glioblastoma

    Giulia Fianco, Maria Patrizia Mongiardi ... Daniela Barilà
    Retention of Caspase-8 confers a selective advantage to glioblastoma and represents a novel therapeutic target.

    Inflammatory stress signaling via NF-kB alters accessible cholesterol to upregulate SREBP2 transcriptional activity in endothelial cells

    Joseph Wayne M Fowler, Rong Zhang ... William C Sessa
    Detailed biochemical and metabolic analysis of the inflammatory response in human endothelial cells reveals that inflammation directly regulates cholesterol homeostasis.
