Divergence of a Tandem Duplication of Manganese Superoxide Dismutase in Nosema bombycis (opens in new window)
JOURNAL OF EUKARYOTIC MICROBIOLOGY 2018 JAN-FEB; 65(1):93-103
Manganese superoxide dismutase (MnSOD) is a key enzyme in the protection of cells from oxidative stress. A tandem duplication of the MnSOD gene (NbMnSOD1 and NbMnSOD2) in the genome of Nosema bombycis, a parasite of the silkworm Bombyx mori, was previously identified. Here, we compare the protein structures of NbMnSOD1 and NbMnSOD2 and characterize these two proteins in terms of cellular localization, timing of transcription, protein structure, and enzyme activity. Despite a similarity in the primary sequence of NbMnSOD1 and NbMnSOD2, the latter shows a remarkable degree of amino acid sequence difference on the protein's surface and in the active site, where there is a substitution of a phenylalanine for a histidine in NbMnSOD2. Immuno-electron microscopy demonstrates that NbMnSOD1 is present in the cytosol of mature spores, whereas NbMnSOD2 is localized on the polar tube and the spore wall. Immunofluorescence confirms the localization of NbMnSOD2 on the polar tube of the germinated spore. Quantitative measurement of gene expression (qRT-PCR) demonstrates production of both alleles during the first day of infection followed by a dramatic decrease during the second to fourth day of infection. From the fifth day onward, the two alleles show a complementary pattern of expression. The qRT-PCR of the host manganese superoxide dismutase (BmMnSOD) shows a notable increase in transcription upon infection, leading to a three-fold spike by the first day of infection, followed by a decrease in transcription. Measurement of overall MnSOD activity shows a similar peak at day 1 followed by a decrease to a constant rate of enzyme activity. The differences in cellular localization and pattern of gene expression of NbMnSOD2 compared to NbMnSOD1, as well as the differences in protein structure seen for NbMnSOD2 compared to other microsporidial MnSODs, strongly suggest a unique, recently evolved role for NbMnSOD2.

Chromosomal instability during neurogenesis in Huntington's disease (opens in new window)
DEVELOPMENT 2018 JAN; 145(2):? Article UNSP dev156844
Huntington's disease (HD) is a fatal neurodegenerative disease caused by expansion of CAG repeats in the Huntingtin gene (HTT). Neither its pathogenic mechanisms nor the normal functions of HTT are well understood. To model HD in humans, we engineered a genetic allelic series of isogenic human embryonic stem cell (hESC) lines with graded increases in CAG repeat length. Neural differentiation of these lines unveiled a novel developmental HD phenotype: the appearance of giant multinucleated telencephalic neurons at an abundance directly proportional to CAG repeat length, generated by a chromosomal instability and failed cytokinesis over multiple rounds of DNA replication. We conclude that disrupted neurogenesis during development is an important, unrecognized aspect of HD pathogenesis. To address the function of normal HTT protein we generated HTT+/- and HTT-/- lines. Surprisingly, the same phenotype emerged in HTT-/- but not HTT+/- lines. We conclude that HD is a developmental disorder characterized by chromosomal instability that impairs neurogenesis, and that HD represents a genetic dominant-negative loss of function, contrary to the prevalent gain-of-toxic-function hypothesis. The consequences of developmental alterations should be considered as a new target for HD therapies.

Stimulation of Hair Cells with Ultraviolet Light (opens in new window)
TO THE EAR AND BACK AGAIN - ADVANCES IN AUDITORY BIOPHYSICS 2018; 1965(?):? Article UNSP 060005
Hair bundles are specialized organelles that transduce mechanical inputs into electrical outputs. To activate hair cells, physiologists have resorted to mechanical methods of hair-bundle stimulation. Here we describe a new method of hair-bundle stimulation, irradiation with ultraviolet light. A hair bundle illuminated by ultraviolet light rapidly moves towards its tall edge, a motion typically associated with excitatory stimulation. The motion disappears upon tip-link rupture and is associated with the opening of mechanotransduction channels. Hair bundles can be induced to move sinusoidally with oscillatory modulation of the stimulation power. We discuss the implications of ultraviolet stimulation as a novel hair-bundle stimulus.

Immunologic, microbial, and epithelial interactions in atopic dermatitis (opens in new window)
ANNALS OF ALLERGY ASTHMA & IMMUNOLOGY 2018 JAN; 120(1):34-41
Objective: To provide an overview of studies contributing to the understanding of immunologic, microbial, and epithelial interactions in atopic dermatitis. Data Sources: PubMed literature review (2000-2017) and meeting abstracts from recent international dermatology conferences. Study Selections: Articles discussing primarily human disease. Results: Clinical studies showed that atopic dermatitis is a type 2 immune-centered disease with a systemic inflammatory component but with heterogeneous treatment responses. This suggests that other factors are likely involved in shaping the skin disease phenotype, including microbial dysbiosis and epidermal barrier dysfunction. Conclusion: Recent clinical investigation has significantly expanded our knowledge on disease pathogenesis in atopic dermatitis, and current and future clinical trials will most likely further help to elucidate this complex, heterogeneous skin disease.

Incomplete prophage tolerance by type III-A CRISPR-Cas systems reduces the fitness of lysogenic hosts (opens in new window)
NATURE COMMUNICATIONS 2018 JAN 4; 9(?):? Article 61
CRISPR-Cas systems offer an immune mechanism through which prokaryotic hosts can acquire heritable resistance to genetic parasites, including temperate phages. Co-transcriptional DNA and RNA targeting by type III-A CRISPR-Cas systems restricts temperate phage lytic infections while allowing lysogenic infections to be tolerated under conditions where the prophage targets are transcriptionally repressed. However, long-term consequences of this phenomenon have not been explored. Here we show that maintenance of conditionally tolerant type III-A systems can produce fitness costs within populations of Staphylococcus aureus lysogens. The fitness costs depend on the activity of prophage-internal promoters and type III-A Cas nucleases implicated in targeting, can be more severe in double lysogens, and are alleviated by spacer-target mismatches which do not abrogate immunity during the lytic cycle. These findings suggest that persistence of type III-A systems that target endogenous prophages could be enhanced by spacer-target mismatches, particularly among populations that are prone to polylysogenization.

Modeling the effect of boost timing in murine irradiated sporozoite prime-boost vaccines (opens in new window)
PLOS ONE 2018 JAN 12; 13(1):? Article e0190940
Vaccination with radiation-attenuated sporozoites has been shown to induce CD8+ T cell-mediated protection against pre-erythrocytic stages of malaria. Empirical evidence suggests that successive inoculations often improve the efficacy of this type of vaccines. An initial dose (prime) triggers a specific cellular response, and subsequent inoculations (boost) amplify this response to create a robust CD8+ T cell memory. In this work we propose a model to analyze the effect of T cell dynamics on the performance of prime-boost vaccines. This model suggests that boost doses and timings should be selected according to the T cell response elicited by priming. Specifically, boosting during late stages of clonal contraction would maximize T cell memory production for vaccines using lower doses of irradiated sporozoites. In contrast, single-dose inoculations would be indicated for higher vaccine doses. Experimental data have been obtained that support theoretical predictions of the model.

Search for low mass vector resonances decaying into quark-antiquark pairs in proton-proton collisions at root s=13 TeV (opens in new window)
JOURNAL OF HIGH ENERGY PHYSICS 2018 JAN 22; ?(1):? Article 097
A search for narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in proton-proton collisions at root s = 13 TeV with the CMS detector at the LHC, corresponding to an integrated luminosity of 35.9 fb(-1). The hypothetical resonance is produced with sufficiently high transverse momentum that its decay products are merged into a single jet with two-prong substructure. A signal would be identified as a peak over a smoothly falling background in the distribution of the invariant mass of the jet, using novel jet substructure techniques. No evidence for such a resonance is observed within the mass range of 50-300 GeV. Upper limits at 95% confidence level are set on the production cross section, and presented in a mass-coupling parameter space. The limits further constrain simplified models of dark matter production involving a mediator interacting between quarks and dark matter particles through a vector or axial-vector current. In the framework of these models, the results are the most sensitive to date, extending for the first time the search region to masses below 100 GeV.

An Optimized Synthetic-Bioinformatic Natural Product Antibiotic Sterilizes Multidrug-Resistant &ITAcinetobacter baumannii&IT-Infected Wounds (opens in new window)
MSPHERE 2018 JAN-FEB; 3(1):? Article e00528-17
The antibiotic paenimucillin A was originally identified using a culture-independent synthetic-bioinformatic natural product (syn-BNP) discovery approach. Here we report on a bioinformatics-guided survey of paenimucillin A analogs that led to the discovery of paenimucillin C. Paenimucillin C inhibits the growth of multidrug-resistant (MDR) Acinetobacter baumannii clinical isolates, as well as other Gram-negative bacterial pathogens. In a rat cutaneous wound model, it completely sterilized MDR A. baumannii wound infections with no sign of rebound. Mechanistic studies point to a membrane-associated mode of action that results in leakage of intracellular contents.& para;& para;IMPORTANCE Natural product-inspired antibiotics have saved millions of lives and played a critical role in modern medicine. However, the emergence of drug-resistant pathogens is outpacing the rate at which new clinically useful antibiotics are being discovered. The lack of a means to combat infections caused by multidrug-resistant ( MDR) Acinetobacter baumannii is of particular concern. The sharp increase in cases of MDR A. baumannii infections in recent years prompted the CDC (https://urldefense.proofpoint.com/v2/url?u=https-3A__www.cdc.gov_drugresistance_biggest-5Fthreats.html&d=DwIDaQ&c=JeTkUgVztGMmhKYjxsy2rfoWYibK1YmxXez1G3oNStg&r=bWJiylK2oqB9vBxAFHE1PJcvSYL9TVkBaaVMsMDsLbs&m=2yuUL-2W7Hn85BsfNdK7hhyh8bnrdh_fMoQqJ9Htz3A&s=bDZnP6LOg-9-zPxCn3yWB-BTWAqDNVhYprYUDiz_xg0&e=) and WHO (https://urldefense.proofpoint.com/v2/url?u=http-3A__www.who.int_medicines_publications_global-2Dpriority-2Dlist-2Dantibiot&d=DwIDaQ&c=JeTkUgVztGMmhKYjxsy2rfoWYibK1YmxXez1G3oNStg&r=bWJiylK2oqB9vBxAFHE1PJcvSYL9TVkBaaVMsMDsLbs&m=2yuUL-2W7Hn85BsfNdK7hhyh8bnrdh_fMoQqJ9Htz3A&s=mLdKhjQZCnXH_xMNCKtB0EJAsaf-aR0e8Zxzzn4pctE&e= ic-resistant-bacteria/en/) to list this pathogen as a "serious threat" and "critical pathogen,"respectively. Here we report a new antibiotic, paenimucillin C, active against Gram-negative bacterial pathogens, including many clinical isolates of MDR A. baumannii strains. Mechanistic studies point to membrane disruption leading to leakage of intracellular contents as its antibacterial mode of action. Paenimucillin C sterilizes MDR A. baumannii infections in a rat cutaneous wound model with no sign of rebound infection, providing a potential new therapeutic regimen.
