    Quantification of Serum Ovalbumin-specific Immunoglobulin E Titre via in vivo Passive Cutaneous Anaphylaxis Assay
    Murine models of allergic airway disease are frequently used as a tool to elucidate the cellular and molecular mechanisms of tissue-specific asthmatic disease pathogenesis. Paramount to the success of these models is the induction of experimental ...
    Early Life Ovalbumin Sensitization and Aerosol Challenge for the Induction of Allergic Airway Inflammation in a BALB/c Murine Model
    The early life period represents a time of immunological plasticity whereby the functionally immature immune system is highly susceptible to environmental stimulation. Perennial aeroallergen and respiratory viral infection induced sporadic episodes ...
    Characterization of Mouse Adult Testicular Macrophage Populations by Immunofluorescence Imaging and Flow Cytometry
    Authors:  Noushin Mossadegh-Keller and Michael H. Sieweke, date: 03/05/2019, view: 206, Q&A: 0
    Testicular macrophages (tMΦ) are the most abundant immune cells residing in the testis, an immune-privileged organ. TMΦ are known to exhibit different functions, such as protecting spermatozoa from auto-immune attack by producing immunosuppressive ...
    Acute Cerebellar Slice Preparation Using a Tissue Chopper
    Authors:  Yubin Wang and Michel Baudry, date: 03/05/2019, view: 159, Q&A: 0
    Acute cerebellar slices are widely used among neuroscientists to study the properties of excitatory and inhibitory synaptic transmission as well as intracellular signaling pathways involved in their regulation in cerebellum. The cerebellar cortex ...
    Single-cell Motility Analysis of Tethered Human Spermatozoa
    Authors:  William M. Skinner, Nadja Mannowetz, Polina V. Lishko and Nadia R. Roan, date: 03/05/2019, view: 241, Q&A: 0
    Vigorous sperm flagellar motility is essential for fertilization, and so the quantitative measurement of motility is a useful tool to assess the intrinsic fertility potential of sperm cells and explore how various factors can alter sperm’s ability ...
    Differentiation of Human Induced Pluripotent Stem Cells (iPSCs) into an Effective Model of Forebrain Neural Progenitor Cells and Mature Neurons
    Induced Pluripotent Stem Cells (iPSCs) are pluripotent stem cells that can be generated from somatic cells, and provide a way to model the development of neural tissues in vitro. One particularly interesting application of iPSCs is the ...

    In many fields of biology, especially in the field of developmental biology, LacZ reporter staining is an approach used to monitor gene expression patterns. In the LacZ reporter system, the LacZ gene is inserted in the ...
    A New Efficient Method for Measuring Oxygen Consumption Rate Directly ex vivo in Human Epidermal Biopsies
    Authors:  Daniel Schniertshauer, Daniel Gebhard and Jörg Bergemann, date: 03/05/2019, view: 174, Q&A: 0
    Skin cells are constantly exposed to environmental influences such as air pollution, chemicals, pathogens and UV radiation. UV radiation can damage different biological structures, but most importantly cellular DNA. Mitochondria contain their own ...
    Quantification of Serum Ovalbumin-specific Immunoglobulin E Titre via in vivo Passive Cutaneous Anaphylaxis Assay
    [Abstract] Murine models of allergic airway disease are frequently used as a tool to elucidate the cellular and molecular mechanisms of tissue-specific asthmatic disease pathogenesis. Paramount to the success of these models is the induction of experimental antigen sensitization, as indicated by the presence of antigen-specific serum immunoglobulin E. The ...
    Early Life Ovalbumin Sensitization and Aerosol Challenge for the Induction of Allergic Airway Inflammation in a BALB/c Murine Model
    [Abstract] The early life period represents a time of immunological plasticity whereby the functionally immature immune system is highly susceptible to environmental stimulation. Perennial aeroallergen and respiratory viral infection induced sporadic episodes of lung inflammation during this temporal window represent major risk factors for initiation of ...
    Characterization of Mouse Adult Testicular Macrophage Populations by Immunofluorescence Imaging and Flow Cytometry
    Authors:  Noushin Mossadegh-Keller and Michael H. Sieweke, date: 03/05/2019, view: 206, Q&A: 0
    [Abstract] Testicular macrophages (tMΦ) are the most abundant immune cells residing in the testis, an immune-privileged organ. TMΦ are known to exhibit different functions, such as protecting spermatozoa from auto-immune attack by producing immunosuppressive cytokines and trophic roles in supporting spermatogenesis and male sex hormone production. They also ...
    Acute Cerebellar Slice Preparation Using a Tissue Chopper
    Authors:  Yubin Wang and Michel Baudry, date: 03/05/2019, view: 159, Q&A: 0
    [Abstract] Acute cerebellar slices are widely used among neuroscientists to study the properties of excitatory and inhibitory synaptic transmission as well as intracellular signaling pathways involved in their regulation in cerebellum. The cerebellar cortex presents a well-organized circuitry, and several neuronal pathways can be stimulated and recorded ...
    Single-cell Motility Analysis of Tethered Human Spermatozoa
    Authors:  William M. Skinner, Nadja Mannowetz, Polina V. Lishko and Nadia R. Roan, date: 03/05/2019, view: 241, Q&A: 0
    [Abstract] Vigorous sperm flagellar motility is essential for fertilization, and so the quantitative measurement of motility is a useful tool to assess the intrinsic fertility potential of sperm cells and explore how various factors can alter sperm’s ability to reach the egg and penetrate its protective layers. Human sperm beat their flagella many times each ...
    Differentiation of Human Induced Pluripotent Stem Cells (iPSCs) into an Effective Model of Forebrain Neural Progenitor Cells and Mature Neurons
    [Abstract] Induced Pluripotent Stem Cells (iPSCs) are pluripotent stem cells that can be generated from somatic cells, and provide a way to model the development of neural tissues in vitro. One particularly interesting application of iPSCs is the development of neurons analogous to those found in the human forebrain. Forebrain neurons play a central ...

    [Abstract] In many fields of biology, especially in the field of developmental biology, LacZ reporter staining is an approach used to monitor gene expression patterns. In the LacZ reporter system, the LacZ gene is inserted in the endogenous location of the target gene via gene knock-in or by constructing a transgenic cassette in ...

    [Abstract] Skin cells are constantly exposed to environmental influences such as air pollution, chemicals, pathogens and UV radiation. UV radiation can damage different biological structures, but most importantly cellular DNA. Mitochondria contain their own genome and accumulate UV-induced DNA mutations to a large extent. This can result, e.g., in ...
    DNA Immunization Using in vivo Electroporation for Generating Monoclonal Antibodies Against Mouse IL-9R
    [Abstract] Membrane proteins such as cytokine receptors and G protein-coupled receptors can be drug targets. Recently, we have generated specific monoclonal antibodies (mAbs) against the mouse IL-9 receptor (IL-9R) and found that IL-9R on memory B cells have critical roles in T-dependent immune response. So far, most antibodies against cell surface proteins ...
    Induced Germinal Center B Cell Culture System
    Authors:  Kei Haniuda and Daisuke Kitamura, date: 02/20/2019, view: 580, Q&A: 0
    [Abstract] The germinal center (GC) is the site where B cells undergo clonal expansion, affinity-based selection, and differentiation into memory B cells or plasma cells. It has been difficult to elucidate regulatory mechanisms for the dynamic GC B cell maturation and differentiation, partly because experimental manipulation of GC B cells in vivo ...
