    Eicosanoid Isolation from Mouse Intestinal Tissue for ELISA
    Author:  Isabella Rauch, date: 11/05/2018, view: 1492, Q&A: 0
    [Abstract] Activation of inflammasomes in peritoneal macrophages and intestinal epithelial cells (IEC) leads to the release of eicosanoids. To assess the amount of eicosanoids released by IEC, lipids need to be isolated from whole tissue previous to analysis by lipid mass spectrometry or ELISA. This protocol describes how to isolate lipids from intestinal ...
    Purification of Total RNA from DSS-treated Murine Tissue via Lithium Chloride Precipitation
    Authors:  Emilie Viennois, Anika Tahsin and Didier Merlin, date: 05/05/2018, view: 3304, Q&A: 0
    [Abstract] We have developed a protocol to purify RNA from DSS (Dextran Sulfate Sodium)-treated mouse tissues. This method, which prevents downstream inhibition of q-RT-PCR observed in DSS-treated tissues, relies on successive precipitations with lithium chloride.
    Oral Microbiome Characterization in Murine Models
    [Abstract] The oral microbiome has been implicated as a trigger for immune responsiveness in the oral cavity, particularly in the setting of the inflammatory disease periodontitis. The protocol presented here is aimed at characterizing the oral microbiome in murine models at steady state and during perturbations of immunity or physiology. Herein, we describe ...
    Analyzing the Properties of Murine Intestinal Mucins by Electrophoresis and Histology
    Authors:  Ran Wang and Sumaira Z. Hasnain, date: 07/20/2017, view: 10102, Q&A: 0
    [Abstract] Specialized secretory cells known as goblet cells in the intestine and respiratory epithelium are responsible for the secretion of mucins. Mucins are large heavily glycosylated proteins and typically have a molecular mass higher than 106 Da. These large proteins are densely substituted with short glycan chains, which have many important ...
    Mouse Model of Reversible Intestinal Inflammation
    [Abstract] Current therapies to treat inflammatory bowel disease by dampening excessive inflammatory immune responses have had limited success (Reinisch et al., 2011; Rutgeerts et al., 2005; Sandborn et al., 2012). To develop new therapeutic interventions, there is a need for better understanding of the mechanisms that are ...
    Preparation of Protein-containing Extracts from Microbiota-rich Intestinal Contents
    [Abstract] The contribution of microbiota in regulating multiple physiological and pathological host responses has been studied intensively in recent years. Evidence suggests that commensal microbiota can directly modulate different populations of cells of the immune system (e.g., Ivanov et al., 2008; Atarashi et al., 2011). ...
