The research field opened by this discovery led to the identification of three isotypes, namely PPARa （NR1C1）, PPAR[3/6 （NRIC2）, PPARy （NRIC3）, in a wide range of tissues. All these receptors act as ligand-activated transcription factors, binding lipid molecules with different, though overlapping, specificity.展开更多
