Abstract

The base of the leptin resistance hypothesis promulgated several years ago consists of two tenets: the extinction of leptin-induced intracellular signaling downstream of leptin binding to the long form of neuronal receptor (LTRb) in the hypothalamus and impedance to leptin entry imposed at the blood-brain barrier (BBB). A recent comprehensive literature review [1] has led to the conclusion that central leptin insufficiency associated with the metabolic syndrome is due to reduced BBB leptin transport efficiency, and not just to leptin insensitivity in the hypothalamus.
