Peroxisome proliferator-activated receptors (PPAR)-α and -γ in astrocytes play important roles in inflammatory brain pathologies. Understanding the regulation of both activity and expression levels of PPARs is an important neuroscience issue. Toll-like receptor (TLR) agonists are inflammatory stimuli that could modulate PPAR, but the mechanisms of their(More)
Peroxisome proliferator-activated receptor β/δ (PPARβ/δ) is a potential regulator of neuroinflammation. Toll-like receptors (TLR) are innate immunity-related receptors of inflammatory stimuli. In the present report, we evaluate the molecular mechanisms of regulation of mRNA, protein, and transcriptional activity levels of PPARβ/δ by agonists of TLR4,(More)
Epidemiological studies have shown that severe inflammatory responses occur in patients with hyperglycemia. The molecular nature of these changes is currently under intense investigations. A central role of nuclear receptors PPAR has been shown in the regulation of metabolic changes associated with hyperglycemia, a selective agonist of nuclear receptor(More)
It has recently become clear that regulation of mRNA stability plays an important role in the development of cell responses to stimulation of toll-like receptors during inflammation. This discovery motivated a search for low molecular weight substances modulating the stability of mRNA encoding proteins involved in inflammatory responses. In this work,(More)
Endotoxin tolerance (ET) represents a state of an altered immune response induced by multiple stimulations of a cell, a tissue, or an organism with lipopolysaccharide. Characteristics of ET include downregulation of induction of proinflammatory genes (TNFα, IL6, and others) and enhancement of induction of antiinflammatory genes (IL10, TGFβ). ET generally(More)
