BACKGROUND Adipose tissue inflammation may play a critical role in the pathogenesis of insulin resistance (IR). The present study examined the role of lymphocytes in adipose tissue inflammation and IR. METHODS AND RESULTS In a mouse model of obesity-mediated IR, high-fat diet (HFD) induced IR already after 5 weeks, which was associated with a marked(More)
The endothelium releases multiple mediators, not only regulators of vasomotor function but also important physiological and pathophysiological inflammatory mediators. Endothelial dysfunction is caused by chronic exposure to various stressors such as oxidative stress and modified low-density lipoprotein (LDL) cholesterol, resulting in impaired nitric oxide(More)
OBJECTIVE The angiotensin type 1 receptor blocker (ARB) and peroxisome proliferator-activated receptor (PPAR) gamma modulator telmisartan has been recently demonstrated to reduce plasma triglycerides in nondiabetic and diabetic hypertensive patients. The present study investigates the molecular mechanisms of telmisartans hypolipidemic actions, in particular(More)
Estrogen receptors (ER) are important regulators of metabolic diseases such as obesity and insulin resistance (IR). While ERalpha seems to have a protective role in such diseases, the function of ERbeta is not clear. To characterize the metabolic function of ERbeta, we investigated its molecular interaction with a master regulator of insulin(More)
BACKGROUND Inflammation of adipose tissue (AT) has been recently accepted as a first step towards obesity-mediated insulin resistance. We could previously show that mice fed with high fat diet (HFD) develop systemic insulin resistance (IR) and glucose intolerance (GI) associated with CD4-positive T-lymphocyte infiltration into visceral AT. These(More)
When normal endothelial function is shifted to a pathological degree, the foundation is laid for possibly following diseases. This endothelial dysfunction is characterized by a proinflammatory state, reduced vasodilation, and a prothrombotic state. In the continuation this dysfunction is strongly associated cardiovascular morbidity and mortality.(More)
Estrogen receptors (ER) are important regulators of metabolic diseases such as obesity and insulin resistance (IR). While ERa seems to have a protective role in such diseases, the function of ERb is not clear. To characterize the metabolic function of ERb, we investigated its molecular interaction with a master regulator of insulin signaling/glucose(More)
Migration of CD4-positive lymphocytes into the vessel wall represents an important step in early atherogenesis. Telmisartan is an angiotensin type 1 receptor (AT1R) blocker with peroxisome proliferator-activated receptor (PPAR)-gamma-activating properties. The present study examined the effect of telmisartan on CD4-positive cell migration and the role of(More)
