PPARs
Peroxisome Proliferator-activated Receptors (PPARs) are nuclear receptors involved in lipid and glucose homeostasis, inflammation and wound healing.
Peroxisome proliferator-activated receptors (PPARs) are lipid-activated transcription factors belonging to the superfamily of nuclear receptors that modulate the transcription of genes responsible for regulating lipid and lipoprotein metabolism, glucose homeostasis and inflammation along with numerous other cellular processes.
The PPAR family consists of three proteins:
1. Alpha
2. Beta/Delta
3. Gamma
Recent data suggest that PPAR alpha and gamma activation decreases atherosclerosis progression not only by correcting metabolic disorders, but also through direct effects on the vascular wall.
The peroxisome proliferator-activated receptors (PPARs) play central roles in lipid and glucose homeostasis, cellular differentiation, and the immune/inflammatory response.
PPARs modulate the recruitment of leukocytes to endothelial cells, control the inflammatory response and lipid homeostasis of monocytes/macrophages and regulate inflammatory cytokine production by smooth muscle cells.
In addition to ligand binding, phosphorylation can regulate PPARs; the biological effects of phosphorylation depend on the stimulus, the kinase, the PPAR isotype, the residue modified, the cell type and the promoter investigated.
