    Herpes Simplex Virus Type 1 Propagation, Titration and Single-step Growth Curves
    Given the endemic seroprevalence of herpes simplex viruses (HSV), its associated human diseases, and the emergence of acyclovir-resistant strains, there is a continuous need for better antiviral therapies. Towards this aim, identifying mechanistic ...
    Localizing Genome Segments and Protein Products of a Multipartite Virus in Host Plant Cells
    Authors:  Marie-Stephanie Vernerey, Elodie Pirolles, Stephane Blanc and Anne Sicard, date: 12/05/2019, view: 94, Q&A: 0
    A founding paradigm in virology is that the spatial unit of the viral replication cycle is an individual cell. This concept applied to multipartite viruses–which have a genome composed of two or more nucleic acid segments, each individually ...

    Authors:  Nils Y. Meiresonne, Elisa Consoli, Laureen M.Y. Mertens and Tanneke den Blaauwen, date: 12/05/2019, view: 127, Q&A: 0
    This protocol was developed to qualitatively and quantitatively detect protein-protein interactions in all compartments of Escherichia coli by Förster Resonance Energy Transfer (FRET) using the Superfolder mTurquoise2 ox-mNeonGreen FRET ...
    Quantification of Nitric Oxide and Reactive Oxygen Species in Leishmania-infected J774A.1 Macrophages as a Response to the in vitro Treatment with a Natural Product Compound
    Authors:  Kalliopi Karampetsou, Olga S. Koutsoni and Eleni Dotsika, date: 12/05/2019, view: 64, Q&A: 0
    Leishmaniasis is a parasitic disease caused by the obligatory intracellular protozoa Leishmania spp. Current therapeutic options are limited and thus, drug discovery against leishmaniasis is very important. Nevertheless, there is a great ...
    Intracellular cAMP Measurements in Candida albicans Biofilms
    Authors:  Liuliu Jiang, Shengyan Chen, Kairui Sun, Peng Zhou and Xin Wei, date: 12/05/2019, view: 76, Q&A: 0
    Candida albicans is the most common cause of fungal infections worldwide. Infection by C. albicans is closely associated with its ability to form a biofilm, closely packed communities of cells attached to the surfaces of human ...
    Herpes Simplex Virus Type 1 Propagation, Titration and Single-step Growth Curves
    [Abstract] Given the endemic seroprevalence of herpes simplex viruses (HSV), its associated human diseases, and the emergence of acyclovir-resistant strains, there is a continuous need for better antiviral therapies. Towards this aim, identifying mechanistic details of how HSV-1 manipulates infected cells, how it modulates the immune responses, and how it ...
    Localizing Genome Segments and Protein Products of a Multipartite Virus in Host Plant Cells
    Authors:  Marie-Stephanie Vernerey, Elodie Pirolles, Stephane Blanc and Anne Sicard, date: 12/05/2019, view: 94, Q&A: 0
    [Abstract] A founding paradigm in virology is that the spatial unit of the viral replication cycle is an individual cell. This concept applied to multipartite viruses–which have a genome composed of two or more nucleic acid segments, each individually encapsulated–implies that all segments constituting a viral genome need to coinfect the same host cell for ...
    Detection of in vivo Protein Interactions in All Bacterial Compartments by Förster Resonance Energy Transfer with the Superfolder mTurquoise2 ox-mNeongreen FRET Pair
    Authors:  Nils Y. Meiresonne, Elisa Consoli, Laureen M.Y. Mertens and Tanneke den Blaauwen, date: 12/05/2019, view: 127, Q&A: 0
    [Abstract] This protocol was developed to qualitatively and quantitatively detect protein-protein interactions in all compartments of Escherichia coli by Förster Resonance Energy Transfer (FRET) using the Superfolder mTurquoise2 ox-mNeonGreen FRET pair (sfTq2ox-mNG). This FRET pair has more than twice the detection range for FRET ...
    Quantification of Nitric Oxide and Reactive Oxygen Species in Leishmania-infected J774A.1 Macrophages as a Response to the in vitro Treatment with a Natural Product Compound
    Authors:  Kalliopi Karampetsou, Olga S. Koutsoni and Eleni Dotsika, date: 12/05/2019, view: 64, Q&A: 0
    [Abstract] Leishmaniasis is a parasitic disease caused by the obligatory intracellular protozoa Leishmania spp. Current therapeutic options are limited and thus, drug discovery against leishmaniasis is very important. Nevertheless, there is a great difficulty to develop therapeutic strategies against the disease because the parasite deploys various ...
    Intracellular cAMP Measurements in Candida albicans Biofilms
    Authors:  Liuliu Jiang, Shengyan Chen, Kairui Sun, Peng Zhou and Xin Wei, date: 12/05/2019, view: 76, Q&A: 0
    [Abstract] Candida albicans is the most common cause of fungal infections worldwide. Infection by C. albicans is closely associated with its ability to form a biofilm, closely packed communities of cells attached to the surfaces of human tissues and implanted devices, in or on the host. When tested for susceptibility to antifungals, such as ...
    Imaging Cryptococcus spp. Capsule by Differential Interference Contrast Microscopy Using Percoll®
    [Abstract] The most important virulence factor in the Cryptococcus genus is the polysaccharide capsule. This genus includes several species that cause life-threatening invasive disease. An increase in capsule thickness is important during fungal infection. The capsule is usually imaged using India ink, and crucial insights on the dynamics of its ...
    Method for Assessing Virulence of Colletotrichum higginsianum on Arabidopsis thaliana Leaves Using Automated Lesion Area Detection and Measurement
    Authors:  Ayako Tsushima, Pamela Gan and Ken Shirasu, date: 11/20/2019, view: 566, Q&A: 0
    [Abstract] The plant pathogenic fungus, Colletotrichum higginsianum is widely used to understand infection mechanisms, as it infects the model plant Arabidopsis thaliana. To determine the virulence of C. higginsianum, several methods have been developed, such as disease reaction scoring, lesion measurement, entry rate assays, and ...
    Assessing Different Ways of Bacillus subtilis Spreading over Abiotic Surfaces
    Authors:  Marco Bartolini and Roberto Grau, date: 11/20/2019, view: 305, Q&A: 0
    [Abstract] Surface-associate motility on biotic and abiotic environments is a key mechanism used by the model bacterium Bacillus subtilis and its closest relatives (i.e., B. amyloliquefaciens, B. thuringiensis, B. cereus, B. pumilus) for surface colonization and spreading across surfaces. The study of ...
    Leishmania Parasite Quantification by Bioluminescence in Murine Models
    Authors:  Marta Reverte and Nicolas Fasel, date: 11/20/2019, view: 189, Q&A: 0
    [Abstract] Leishmaniasis remains a major public health problem worldwide with a prevalence of 12 million, an incidence of 1 million persons, and 350 million people being at risk. Murine models have been largely used for studying the host-pathogen relationship and developing effective chemotherapies against Leishmania parasites. Thus, preclinical ...
    Model of Chemotherapy-associated Mucositis and Oral Opportunistic Infections
    Authors:  Takanori Sobue, Martinna Bertolini, Angela Thompson and Anna Dongari-Bagtzoglou, date: 11/05/2019, view: 203, Q&A: 0
    [Abstract] Oral mucositis is a common complication of cancer chemotherapy treatment. Because of the lack of relevant oral mucositis experimental models, it is not clear how chemotherapeutic agents injure the oral mucosa and if commensal microorganisms accelerate tissue damage. We developed an organotypic oral mucosa model that mimics cellular responses ...
