LEP and Insulin resistance: MS is defined by multiple components (high blood pressure, abdominal obesity, glucose intolerance, and dyslipidemia) of risk factors that arise primarily from insulin resistance mostly mediated by inflammatory cytokines, such as tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6) together with leptin and adiponectin, which are molecules also found in PS [4].
