Besides their well-known anti-diabetic effects, the peroxisome proliferator-activated receptor γ (PPARγ) thiazolidinedione ligands (TZD) have been suggested to also display anti-inflammatory properties. The receptor role in mediating such effects is far from being elucidated. Here, we demonstrate that PPARγ is necessary for TZD to interfere with TNFα and IFNγ inflammatory activity in human endothelial cells. Different PPARγ ligands similarly inhib...

Rosiglitazone interferes with the inflammatory response induced in human endothelial cells by TNFalpha and IFNgamma through a new mechanism involving extracellular signal-regulated kinases (ERKs)

Microvascular endothelium is one of the main character and target involved in the inflammatory response. Upon specific activation, endothelial cells massively recruit Th1 IFNgamma secreting lymphocytes at the inflammatory site. In the present study, we investigate the intracellular signalling mediating TNFalpha (T) and IFNgamma (I) inflammatory response in a human endothelial cell line (HMEC-1) in vitro and the interfering effects of rosiglitazone (RGZ), a peroxisome pr...

White adipose tissue acts as an endocrine organ that secretes a variety of adipokines and coordinates a number of biological processes such as energy homeostasis, neuroendocrine and immune functions. Recent studies demonstrated that abundant adipose tissue depots (particularly visceral adipose tissue), by producing inflammatory cytokines, contribute to chronic low-grade inflammation processes which may underlie the pathogenesis of metabolic disorders such as obesity, atheroscl...
