Obesity is a major risk factor for insulin resistance and type 2 diabetes. Adipose tissue is now considered to be an active endocrine organ that secretes various adipokines such as adiponectin, leptin, resistin, tumour necrosis factor-α, and interleukin-6. Recent studies have shown that these factors might provide a molecular link between increased adiposity and impaired insulin sensitivity. Si...

This chapter is a review of the effects of excessive, formerly known as morbid, obesity on circulating levels and gene expression of adipokines and related factors in the visceral omental adipose tissue of women undergoing bariatric surgery. The current paradigm is that most of the deleterious metabolic effects of excessive obesity are due to Type 2 diabetes and/or hypertension secondary to the...

There is increasing evidence that obesity may have pathophysiological effects that extend beyond its well-known co-morbidities; in particular its role in cancer has received considerable epidemiological support. As adipose tissue becomes strongly established as an endocrine organ, two of its most abundant and most investigated adipokines, leptin and adiponectin, are also taken beyond their trad...

Chronic inflammation and angiogenesis are the most common complications in patients undergoing maintenance peritoneal dialysis (PD), resulting in progressive peritoneum remolding and, eventually, utrafiltration failure. Contributing to the deeper tissue under the peritoneal membrane, adipocytes play a neglected role in this process. Some adipokines act as inflammatory and angiogenic promoters, ...

Several recent studies have found an increased prevalence of non-alcoholic fatty liver disease within psoriasis patients. The exact pathophysiological mechanisms behind these observations are unclear, but are likely related to the high prevalence of obesity and metabolic syndrome within this patient population. Chronic inflammation, mediated by either proinflammatory adipokines or skin-derived ...

The cardiometabolic syndrome, associated with increased cardiovascular disease risk in the industrialized world, is estimated to affect one in four adults. Although the mechanisms linking obesity and cardiovascular disease remain unclear, research continues to unravel the molecular pathways behind this pandemic. Adipose tissue has emerged as a metabolically active participant in mediating vascu...
