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)
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)
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)
