The peroxisome proliferator-activated receptor gamma is a nuclear hormone r
eceptor playing a crucial role in adipogenesis and insulin sensitization. P
rostaglandin J(2) derivates and the antidiabetic thiazolidinediones are its
respective natural and synthetic ligands. The RXR/PPAR gamma heterodimer h
as also been reported to have important immunomodulatory activities and its
pleiotropic functions suggest wide-ranging medical implications. (C) 2001,
