Isolation and in vitro Activation of Mouse Peyer’s Patch Cells from Small Intestine Tissue
[Abstract]  The lumen of gastrointestinal tract is exposed to several potentially pathogenic microorganisms, thus it is extremely relevant to understand how immunosurveilance can be established. Peyer’s Patches (PPs) are oval or round lymphoid nodules that protrude from the outer wall of the ileum portion of small intestine. PPs contain a high percentage of B and T lymphocytes, macrophages and dendritic cells. Here we summarize a protocol for isolation and culture of mouse PP cells, which can be used to ...

Identification of Helminth-induced Type 2 CD4+ T Cells and ILC2s
[Abstract]  After activation, T cells differentiate into different T helper (Th) subsets, namely Th1, Th2, and Th17. These different Th subsets are associated with the production of particular cytokines endowing them with different functions. In immunity against helminth infections the Th2 cell subset plays an important role. Th2 cells typically produce IL-4, IL-5, IL-13, and IL-9 resulting in antibody-isotype switching to IgE, eosinophilia, basophilia, mucin production, and smooth muscle cell ...

Intracellular Cytokine (INF-gamma) Staining Assay
[Abstract]  An intracellular cytokine (INF-gamma) staining assay is used to analyze the function of lymphocytes at the single cell level. By combining surface staining and intracellular cytokine staining, this assay can reveal the percentage of cytokine-releasing cells in a particular population, which cannot be obtained from an ELISpot assay.
