Heme triggers oxidative stress, inflammation, and destruction of cartilage and bone. The haptoglobin-CD163-heme oxygenase-1 (HO-1) pathway circumvents heme toxicity through enzymatic degradation of heme and transcription of antioxidant genes. Plasma-derived factor concentrates contain many proteins that might impact on cellular pathways in joints, blood, and vessels %K Hemophilia A %K Factor VIII %K Platelets %K Macrophages %K Scavenger receptors %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5649264/
