淋巴细胞的旅程

An efficient way to isolate lymphocytes from mouse genital tract is described. This method takes advantage of enzyme digestion and Percoll gradient separation to allow efficient isolation. This technique is also adaptable to for use in other...

Lymphocytes are the major players in adaptive immune responses. Here, we present a lymphocyte purification protocol to determine the physiological functions of the desired molecules in lymphocyte activation in vitro and in vivo. The described experimental procedures are suitable for comparing functional capacities between control and genetically modified...

In this video, we demonstrate the isolation of lymphocytes from a harvested mouse Peyer's patch. The isolated lymphocytes can be used for further...

In this protocol, lymphocytes are placed in the top chamber of a transmigration system, separated from the bottom chamber by a porous membrane. Chemokine is added to the bottom chamber, which induces active migration along a chemokine gradient. After 48 h, lymphocytes are counted in both chambers to quantitate...

This video demonstrates an in vitro technique to stimulate lymphocytes via non-typeable Haemophilus influenzae (NTHi) and to assess the immune response. Incubating isolated peripheral blood mononuclear cells (PBMCs) with NTHi causes the bacterial cells to stimulate T lymphocytes, leading to cytokine production. Upon inhibiting the secretion of cytokines, immunofluorescence staining is performed to detect the accumulated intracellular cytokines in stimulated T...

Here we describe a detailed protocol for the isolation of lymphocytes from the inductive sites including the gut-associated lymphoid tissue Peyer's patches and the draining mesenteric lymph nodes, and the effector sites including the lamina propria and the intestinal epithelium of the small intestinal immune...
