PPARγはいつ発見された
PPARs were originally identified in "Xenopus" frogs as receptors that induce the proliferation of peroxisomes in cells.
The first PPAR (PPARα) was discovered during the search of a molecular target for a group of agents then referred to as "peroxisome proliferators", as they increased peroxisomal numbers in rodent liver tissue, apart from improving insulin sensitivity. These agents, pharmacologically related to the fibrates were discovered in the early 1980s. When it turned out that PPARs played a much more versatile role in biology, the agents were in turn termed "PPAR ligands". The best-known PPAR ligands are the thiazolidinediones; see below for more details.
