Peroxisome proliferation-activated receptor-γ (
PPAR-γ) is a
ligand-activated
transcription factor belonging to the
nuclear hormone receptor superfamily and participates in the
regulation of various
metabolic pathways as well as inflammatory responses.
PPAR-γ
ligands significantly improve myocardial functional recovery and prevent
ischemia-
reperfusion induced
injury. Given the increasing
understanding of the cardioprotective effects of
PPAR-γ
ligands, we know today that the
therapeutic effects of
PPAR-γ
ligands reach far beyond their use as
insulin-
sensitizers, as many of these agents exert beneficial effects in the conditions associated with
ischemia-
reperfusion and
inflammation.
