    ..However, Neoseptin-3 and lipid A form dissimilar molecular contacts to achieve receptor activation; hence strong TLR4/MD-2 agonists need not mimic LPS. ..
  2. McAlpine W, Sun L, Wang K, Liu A, Jain R, San Miguel M, et al. Excessive endosomal TLR signaling causes inflammatory disease in mice with defective SMCR8-WDR41-C9ORF72 complex function. Proc Natl Acad Sci U S A. 2018;115:E11523-E11531 pubmed publisher
    ..Deficiency of WDR41 phenocopied loss of SMCR8. Our findings provide evidence that excessive endosomal TLR signaling resulting from prolonged ligand-receptor contact causes inflammatory disease in SMCR8-deficient mice. ..
  3. Pedersen G, Àdori M, Khoenkhoen S, Dosenovic P, Beutler B, Karlsson Hedestam G. B-1a transitional cells are phenotypically distinct and are lacking in mice deficient in IκBNS. Proc Natl Acad Sci U S A. 2014;111:E4119-26 pubmed publisher
    ..This study identifies a phenotypically distinct splenic population of TrB-1a cells and establishes that the development of B-1a cells is blocked before this stage in the absence of IκBNS. ..
  4. Siggs O, Popkin D, Krebs P, Li X, Tang M, Zhan X, et al. Mutation of the ER retention receptor KDELR1 leads to cell-intrinsic lymphopenia and a failure to control chronic viral infection. Proc Natl Acad Sci U S A. 2015;112:E5706-14 pubmed publisher
    ..Antiviral immunity was also compromised, with Kdelr1 mutant mice unable to clear an otherwise self-limiting viral infection. These data reveal a nonredundant cellular function for KDELR1, upon which lymphocytes distinctly depend. ..
  5. Turer E, San Miguel M, Wang K, McAlpine W, Ou F, Li X, et al. A viable hypomorphic Arnt2 mutation causes hyperphagic obesity, diabetes and hepatic steatosis. Dis Model Mech. 2018;11: pubmed publisher
    ..These findings establish a requirement for ARNT2-dependent genes in the maintenance of the homeostatic feeding response, necessary for prevention of obesity and obesity-related diseases. ..
  6. McAlpine W, Wang K, Choi J, San Miguel M, McAlpine S, Russell J, et al. The class I myosin MYO1D binds to lipid and protects against colitis. Dis Model Mech. 2018;11: pubmed publisher
    ..Moreover, MYO1D appears to couple cytoskeletal elements to lipid in an ATP-dependent manner. These findings demonstrate that MYO1D is needed to maintain epithelial integrity and protect against DSS-induced colitis. ..
  7. Wang Y, Su L, Morin M, Jones B, Mifune Y, Shi H, et al. Adjuvant effect of the novel TLR1/TLR2 agonist Diprovocim synergizes with anti-PD-L1 to eliminate melanoma in mice. Proc Natl Acad Sci U S A. 2018;115:E8698-E8706 pubmed publisher
    ..Diprovocim induced greater frequencies of tumor-infiltrating leukocytes than alum, of which CD8 T cells were necessary for the antitumor effect of immunization plus anti-PD-L1 treatment. ..
  8. Wang Y, Cao L, Lee C, Matsuo T, Wu K, Asher G, et al. Large-scale forward genetics screening identifies Trpa1 as a chemosensor for predator odor-evoked innate fear behaviors. Nat Commun. 2018;9:2041 pubmed publisher
    ..The work establishes the first forward genetics screen to uncover the molecular mechanism of innate fear, a basic emotion and evolutionarily conserved survival mechanism. ..
  9. Wang T, Bu C, Hildebrand S, Jia G, Siggs O, Lyon S, et al. Probability of phenotypically detectable protein damage by ENU-induced mutations in the Mutagenetix database. Nat Commun. 2018;9:441 pubmed publisher
    ..We estimate the proportion of essential autosomal genes in Mus musculus (C57BL/6J) and show that viable mutations in essential genes are more likely to induce phenotype than mutations in non-essential genes. ..
