Proliferator-activated receptor gamma (PPARG), matrix metallopeptidase 9 (MMP-9), interleukin (IL)-8, heat shock protein family A (Hsp70) member 1A (HSPA1A), and toll-like receptor 8 (TLR8) were found to be increased in the whole blood of the HIE group, while C–C motif chemokine receptor 5 (CCR5) was decreased [20]. This evidence concerns the gene MMP9 and perinatal asphyxia.
