Anne Warren Peled,1 Elisabeth A Kappos2 1Private Plastic and Reconstructive Surgery Practice, San Francisco, CA, USA; 2Department of Plastic, Reconstructive, Aesthetic and Hand Surgery, University ...Hospital, Basel, Switzerland Abstract: Lipedema is an uncommon disorder characterized by localized adiposity of the lower extremities, often occurring in females with a family history of the condition. The adiposity extends from hips to ankles and is typically unresponsive to weight loss. In addition to the aesthetic deformity, women also describe pain in the lower extremities, particularly with pressure, as well as easy bruising. Although the condition is well described, it is relatively rare and often misdiagnosed. The purpose of this review is to describe the initial evaluation and diagnosis of lipedema and discuss treatment options. Keywords: lipedema, leg swelling, lipodystrophy, localized adiposity, lower extremity liposuction

Journal Article
In acute experimental autoimmune encephalomyelitis (EAE), demyelination is induced by myelin‐specific CD4+ T lymphocytes and myelin‐specific antibodies. Recovery from the disease is initiated by ...cytokines which suppress T cell expansion and the production of myelin‐toxic molecules by macrophages. Th2/3 cell‐derived signals may also be involved in central nervous system (CNS) repair. Remyelination is thought to be initiated by the recruitment and differentiation of oligodendrocyte precursor cells (OPC) in demyelinated CNS lesions. Here, we report that unlike Th1 cytokines (TNF‐α, IFN‐γ), the Th2/3 cytokine TGF‐β induces primary microglia from C57BL/6 mice to secrete a chemotactic factor for primary OPC. We identified this factor to be the hepatocyte growth factor (HGF). Our studies show that TGF‐β‐1‐2‐3 as well as IFN‐β induce HGF secretion by microglia and that antibodies to the HGF receptor c‐Met abrogate OPC chemotaxis induced by TGF‐β2‐treated microglia. In addition we show spinal cord lesions in EAE induced in SJL/J mice to contain both OPC and HGF producing macrophages in the recovery phase, but not in the acute stage of disease. Taken these findings, TGF‐β may play a pivotal role in remyelination by inducing microglia to release HGF which is both a chemotactic and differentiation factor for OPC.
