摘要
Indirect evidence implicates leptin resistance in the pathogenesis of the lipotoxicity that complicates obesity and results in the metabolic syndrome. In this issue of Developmental Cell, two groups identify protein tyrosine phosphatase 1B (PTP1B) as a cause of leptin resistance through dephosphorylation of Jak2.
