Article Title: Adipose tissue of human omentum is a major source of dendritic cells, which lose MHC Class II and stimulatory function in Crohn's disease.

Figure Lengend Snippet: Fig. 5. Morphology of omental DC. (a) A typical DC from a control omentum is shown. (b) An example of immunogold staining of the veils of a DC. The original bars indicate 1 m. In controls, gold labeling was always 5 gold grains per cell; 10 grains was considered positive. (c) The types of myeloid cells identified in the omental cells from two control patients; the proportion positive for HLA-DR staining is shown in the solid portion of the histograms, and those negative are hatched. M , Macrophage. (d) The gold grains per cell for the surface DR-labeling in the two experiments performed are shown. No evidence of DR-labeling was seen in either of the two Crohn’s patients studied. (e) A light microscopy picture of a cluster of putative DC immunostained with CD11c on a frozen section of omentum from a Crohn’s patient showing the dark, positive-peroxidase staining, which was absent from control slides. Cell nuclei, which were stained with hematoxylin, were distinguishable, showing that the veils were associated with mononuclear cells in the section. (f) Control for e using serum instead of specific antibody and with only hematoxylin staining visible. (g) Frozen section of control omentum, showing two cells specifically labeled for CD83 (TRITC-labeled). (h) The same section as g with label specific for CD86 (FITC-labeled).

Article Snippet: To block nonspecific binding sites, sections were incubated with normal mouse serum for 1 h and then incubated with FITC-conjugated primary antibody to CD86, CD80, or CD40 (Serotec) for 4 h, washed in PBS, and mounted under cover-slips using 4 ,6-diamidino-2-phenylindole-conjugated mounting medium (Vector Laboratories).

Figure Lengend Snippet: ( A ) Expression levels of CD80 + and CD86 + in BMDCs (CD11c + ) and ( B ) production of IL-6 and TNF-α of the cell supernatant measured by ELISA after different treatments (concentration, 2 μg ml −1 NPs) for 24 hours ( n = 3). ( C ) Schematics of experimental design to evaluate the in vivo short-term immune responses activated by a single dose of various LNPs (20 μg/20 g) via subcutaneous injection. ( D ) Percentage of CD80 + and ( E ) CD86 + cells (gated on CD11c + cells) in the LNs at day 3 after immunization ( n = 6). ( F ) Percentage of CD3 + T cells, ( G ) CD8 + T cells (gated on CD3 + T cells), and ( H ) CD4 + T cells (gated on CD3 + T cells) in the spleen at day 3 after immunization ( n = 6). Naive mice without immunization were used as control. * P < 0.05, ** P < 0.01, and *** P < 0.001.

Article Title: Palmitic Acid Esterification Boosts Epigallocatechin Gallate’s Immunomodulatory Effects in Intestinal Inflammation

doi: 10.3390/biom15081208

Figure Lengend Snippet: Dot plots of representative pro-inflammatory (CD86-Coralite ® Plus 647, M1) and propidium iodide double stains of M0 macrophages (differentiated from THP-1 monocytic cells treated with Phorbol-Myristate Acetate) exposed to pro-inflammatory growth media of Caco-2 cells in the presence/absence of epigallocatechin gallate and palmitoyl epigallocatechin gallate. Distinct lowercase letters indicate significantly different values at p < 0.05 according to one-way analyses of variance (ANOVA) and Duncan’s multiple range test ( n = 3).
