    In vitro Differentiation of Thymic Treg Cell Progenitors to Mature Thymic Treg Cells
    体外胸腺调节性T细胞祖细胞向成熟胸腺调节性T细胞的分化
    作者:David L. Owen and Michael A. Farrar日期:08/20/2019,浏览量:45,Q&A: 0
    Thymic Treg cell differentiation occurs via a two-step process. Step one generates Treg cell progenitors (TregP) and is driven by strong TCR interactions with antigens presented in the thymus. Step two is initiated ...
    Fibroblast Gap-closure Assay-Microscopy-based in vitro Assay Measuring the Migration of Murine Fibroblasts
    基于成纤维细胞间隙封闭显微成像的鼠成纤维细胞的体外迁移分析

    [Abstract] Thymic Treg cell differentiation occurs via a two-step process. Step one generates Treg cell progenitors (TregP) and is driven by strong TCR interactions with antigens presented in the thymus. Step two is initiated by activation of STAT5 via IL-2, or IL-15, leading to mature Treg cells capable of ...

    [Abstract] Pulmonary fibrosis is characterized by pathological scaring of the lung. Similar to other fibrotic diseases, scar formation is driven by excessive extracellular matrix deposition by activated, proliferative, and migratory fibroblasts.

    Currently, the two most widely used chemotaxis and cell migration assays are the scratch assay and the ...
    Visualizing Hypoxia in a Murine Model of Candida albicans Infection Using in vivo Biofluorencence
    用活体生物荧光法观察小鼠白念珠菌感染模型中的缺氧情况
    作者:José Pedro Lopes and Constantin F. Urban日期:08/05/2019,浏览量:292,Q&A: 0
    [Abstract] Candida albicans is a leading human fungal pathogen that uses several metabolic adaptations to escape immune cells and causes systemic disease. Here, we describe a protocol for measuring one of these adaptations, the ability to thrive in hypoxic niches. Hypoxia was generated after successful subdermal infection with C. albicans ...
    Precision Technique for Splenectomy Limits Mouse Stress Responses for Accurate and Realistic Measurements for Investigating Inflammation and Immunity
    脾切除术限制小鼠应激反应的精准技术用于精确现实检测炎症和免疫
    作者:Shengwen Calvin Li, Anthony D. Rangel and Mustafa H. Kabeer日期:08/05/2019,浏览量:241,Q&A: 0
    [Abstract] Splenectomy in an animal model requires a standardized technique utilizing best practice to avoid variability which can result in adverse impact to the animal resulting in flawed physiologic responses simply due to technique rather than to the studied variables. In the case of the spleen, often investigators are analyzing the animal immune or ...
    Isolation and Long-term Cultivation of Mouse Alveolar Macrophages
    小鼠肺泡巨噬细胞的分离与长期培养
    作者:Clara Jana-Lui Busch, Jérémy Favret, Laufey Geirsdóttir, Kaaweh Molawi and Michael H. Sieweke日期:07/20/2019,浏览量:788,Q&A: 0
    [Abstract] Alveolar macrophages (AM) are tissue-resident macrophages that colonize the lung around birth and can self-maintain long-term in an adult organism without contribution of monocytes. AM are located in the pulmonary alveoli and can be harvested by washing the lungs using the method of bronchoalveolar lavage (BAL). Here, we compared different ...
    Gentamicin Protection Assay to Determine the Number of Intracellular Bacteria during Infection of Human TC7 Intestinal Epithelial Cells by Shigella flexneri
    庆大霉素保护试验确定福氏志贺菌侵染人TC7肠上皮细胞的胞内寄生数目
    作者:Atin Sharma and Andrea Puhar日期:07/05/2019,浏览量:527,Q&A: 0
    [Abstract] Shigella flexneri is an intracellular bacterial pathogen that gains access to the gut epithelium using a specialized Type III Secretion System (T3SS). Various determinants mediating this invasive infection have been experimentally verified using the classical gentamicin protection assay presented here. In this assay epithelial cell lines ...
    In vitro Infection of Primary Human Monocytes with HIV-1
    原代人单核细胞的体外HIV-1侵染
    作者:Patrick O’Connell, Yong-Hui Zheng, Andrea Amalfitano and Yasser A. Aldhamen日期:07/05/2019,浏览量:493,Q&A: 0
    [Abstract] Monocyte infection by HIV-1 is an important component of chronic HIV pathogenesis. Following infection by HIV-1, monocytes are able to cross the blood brain barrier and set up a viral reservoir in the central nervous system. Additionally, in the setting of chronic HIV-1 infection, monocytes can become activated either directly through HIV-1 ...
    Morphological Evaluation of Wound Healing Events in the Excisional Wound Healing Model in Rats
    在大鼠切除创面愈合模型中进行伤口愈合的形态学评估
    [Abstract] Skin wound healing is a complex process involving different events such as blood coagulation, inflammation, new blood vessels formation, and extracellular matrix deposition. These events can be observed by using histology techniques. However, the lack of the standardization of such parameters impacts on the reproducibility of results. Here, we ...
    Production and Purification of Dengue Virus-like Particles from COS-1 Cells
    从COS-1细胞中制备和纯化登革热病毒样颗粒
    作者:Jedhan Ucat Galula, Gwong-Jen J. Chang and Day-Yu Chao日期:06/20/2019,浏览量:606,Q&A: 0
    [Abstract] Non-infectious virus-like particles (VLPs) containing dengue virus (DENV) pre-membrane (prM) and envelope (E) proteins have been demonstrated to be highly immunogenic and can be used as a potential vaccine candidate as well as a tool for serodiagnostic assays. Successful application of VLPs requires abundant, and high-purity production methods. ...
    Measurement of CD74 N-terminal Fragment Accumulation in Cells Treated with SPPL2a Inhibitor

    作者:Rubén Martínez-Barricarte, Xiao-Fei Kong and Jean-Laurent Casanova日期:06/05/2019,浏览量:517,Q&A: 0
    [Abstract] The recent discovery of human signal peptide peptidase-like 2a (SPPL2a) deficiency in humans revealed the toxicity associated with the accumulation of one of its substrates, CD74 N-terminal fragment (CD74-NTF), for certain type of dendritic cells (cDC2). We developed a two-step protocol for monitoring the accumulation of this molecule in different ...
