FoxO1 regulates Tlr4 inflammatory pathway signalling in macrophages.
The macrophage-mediated inflammatory response is a key etiologic component of obesity-related tissue inflammation and insulin resistance. The transcriptional factor FoxO1 is a key regulator of cell metabolism, cell cycle and cell death. Its activity is tightly regulated by the phosphoinositide-3-kinase-AKT (PI3K-Akt) pathway, which leads to phosphorylation, cytoplasmic retention and inactivatio...
متن کاملTLR4 signalling in the intestine in health and disease.
The colonic epithelium is lined along its apical membrane with approximately 10(14) bacteria/g of tissue. Commensal bacteria outnumber mammalian cells in the gut severalfold. The reason for this degree of commensalism probably resides in the recent recognition of the microbiome as an important source of metabolic energy in the setting of poorly digestible nutrients. As in many themes in biology...
متن کاملHexameric S100A12 is required for pro-inflammatory TLR4-signalling
Introduction The human granulocyte-specific Ca-binding protein S100A12 is particularily over-expressed in autoinflammatory diseases such as juvenile idiopathic arthritis (JIA) as well as other inflammatory conditions (i.e. infections, vasculitides) and has been ascribed to the group of pro-inflammatory damage associated molecular pattern molecules (DAMPs). In order to operate as DAMP, S100A12 r...
متن کاملThe serine protease prostasin regulates hepatic insulin sensitivity by modulating TLR4 signalling
The effects of high-fat diet (HFD) and postprandial endotoxemia on the development of type 2 diabetes are not fully understood. Here we show that the serine protease prostasin (PRSS8) regulates hepatic insulin sensitivity by modulating Toll-like receptor 4 (TLR4)-mediated signalling. HFD triggers the suppression of PRSS8 expression by inducing endoplasmic reticulum (ER) stress and increases the...
متن کاملIntegrin CD11b positively regulates TLR4-induced signalling pathways in dendritic cells but not in macrophages
Tuned and distinct responses of macrophages and dendritic cells to Toll-like receptor 4 (TLR4) activation induced by lipopolysaccharide (LPS) underpin the balance between innate and adaptive immunity. However, the molecule(s) that confer these cell-type-specific LPS-induced effects remain poorly understood. Here we report that the integrin α(M) (CD11b) positively regulates LPS-induced signallin...
