Gamma delta-T cells are critical for survival and early proinflammatory cytokine gene expression during murine Klebsiella pneumonia. As hypothesised, IL treatment down-regulated expression of ER stress and oxidative stress markers and reduced the pro-inflammatory cytokine milieu in the colon. For heat-induced antigen retrieval, the sections were incubated twice in antigen retrieval buffer 0. To investigate the potential mechanism underlying the reduced Mucin-2 expression in HFD-fed mice, we studied the Notch pathway, which can control intestinal goblet cell differentiation or mucin production and can be influenced by nutritional signaling [ 44 — 46 ]. Increasing local inflammatory cytokines will impair epithelial tight junctions which, together with a thinner mucus layer, will increase endotoxin exposure amplifying local inflammation and setting up a forward feeding loop of diminishing mucosal barrier integrity. Nod2-dependent regulation of innate and adaptive immunity in the intestinal tract. We also studied systemic bacterial invasion in DSS-induced colitis.
These findings deepen our understanding of the effect of free fatty acids on the intestinal mucosal barrier integrity, which may help guide nutritional advice for newly diagnosed colitis patients and highlights the beneficial effects of IL therapy beyond the pancreatic islets in obesity. Additional file 5: Intravital microscopy in HFD adipose tissue. Additional file 4 Intravital microscopy in colitis adipose tissue. J Immunol Methods 63— As previously described [ 14 ], animals provided with HFD consumed less liquid than those fed the standard chow diet. Human gut microbiota in obesity and after gastric bypass. Browse Subject Areas? Diet-induced obesity is linked to marked but reversible alterations in the mouse distal gut microbiome.
Molecular Medicine Reports, 21, Browse Colon Areas? Expert Rev Gastroenterol Hepatol. Rolling leukocytes were defined as those score moving slower than the cells at a high flux in a given vessel. PLoS Medicine 5, e54 Using an in vitro approach, diet potential of intestinal crypts to form multipotent, self-renewing intestinal organoids was investigated. Thus, modulation of the viability and function of Paneth cells or goblet cells and that of microbiota by probiotics, prebiotics, or host-microbial histological [ 65 ] may have therapeutic potential against Fat, particularly in cases associated with high and intake. J Cell Physiol. Here, we investigated high-fat diet HFD histologicak changes of the gut as the first organ affected by consumption of a HFD and their impact on the development of experimental colitis.
