Intestinal innate lymphocytes are composed of intraepithelial lymphocytes (IELs) and lamina propria innate lymphoid cells (ILCs). Each intestinal immune compartment is also typified by a unique composition of … Development, Homeostasis, and Functions of Intestinal Intraepithelial Lymphocytes. in vivo. Normal human lamina propria lymphocytes are in a heightened state of activation compared with periph- eral blood with regard to cell-surface activation antigen expression (transferrin receptor, interleu- kin-2 receptor, 4F2) and the increased spontaneous secretion of immunoglobulins in vitro. Lamina propria lymphocytes (see Figure for flow chart of method) Stage 1 Small intestines were removed from animals and handled in batches of three. J Immunol. Would you like email updates of new search results?  |  Most studies of the GI immune system have traditionally focused on the characterization of antigen-specific adaptive immune responses, as they are essential to maintain the mechanism of immune homeostasis by induci… In the present study, we compared the abilities of different staphylococcal superantigens (staphylococcal enterotoxin B [SEB], staphylococcal enterotoxin E [SEE], and toxic shock syndrome toxin 1 [TSST-1]) to stimulate distinct cytokine profiles in peripheral blood mononuclear cells (PBMC), lamina propria lymphocytes (LPL), and intraepithelial lymphocytes (IEL). The epithelial layer harbors intraepithelial lymphocytes (IELs), with very few B cells and antigen-presenting cells, whereas the underlying lamina propria harbors a vast variety of immune cells scattered throughout this connective tissue or aggregated within the lymphoid follicles. intestinal lamina propria lymphocytes (LPL) from patients with Crohn’s disease and control patients using dual immunofluorescence methods. This epithelium is highly infiltrated with lymphocytes and other white blood cells, presenting a greatly altered appearance from the usual pharyngeal epithelium. Front Immunol. 2 0 obj This removed all food remains and much mucus. Conversely, HLA-DR+ intestinal macrophages, which are CD 14" [14], and HLA-DR4 blood monocytes, which are CD14^ contained no detectable lymphocytes (figure 1). B lymphocyteS were not detected within the lamina propria, except when found in and adjacent to lymphoid aggregates. 90% Percoll is referred to as 100% “stock Percoll”. Thus, lamina propria lymphocytes, not macrophages, appear to be the coreceptor-bearing target cells equipped for HIV-1 entry in the lamina propria of the human intestinal mucosa. The find- ings indicate that T-cell subpopulation phenotypes of intestinal LPL differ significantly from peripheral blood lymphocytes (PBL). 2019 Nov 20;2019:6764919. doi: 10.1155/2019/6764919.
