In addition to adipokines, we also found an overproduction of ROS, which damage cellular structures and trigger, together with underproduction of NO, progressive accumulation of fat and, eventually, the development of other pathologies. Bennett, K. Liang, and B. Received Oct 23; Accepted Dec

Another adipokine is omentin, a peptide secreted by visceral fat and, contrary to visfatin, it appears to be produced to a greater degree in vascular stromal cells within the fat than in the adipocytes themselves. Ito et al. America PON -1 activity in overweight and obese children and adolescents: association with obesity-related inflammation and oxidative stress. On the other hand, a reduced level of adiponectin, a significant predictor of cardiovascular mortality, is associated with impaired fasting glucose, leading to type-2 diabetes development, metabolic abnormalities, coronary artery calcification, and stroke. Abstract Purpose: Some researchers found decreased levels of plasma taurine in obese subjects and animals, and reduced expression of an important enzyme of taurine synthesis. Figure 2.

Finally, exposition of adipocytes to high ROS levels suppresses adiponectin expression and secretion [ 26 ]. We propose that age-related exacerbation of obesity-induced vascular oxidative stress and the resulting inflammation and increased cellular senescence increase the risk for the development of vascular diseases in the elderly individuals. Physiologically, ROS can mediate cellular function, receptor signals, and immune responses on vascular cells.
