Haptoglobin is a protein that is mainly expressed by hepatic cells in the liver. Haptoglobin is an acute-phase antioxidant that binds to free hemoglobin (Hb) in the plasma and inhibits the oxidative activity of hemoglobin. Individuals carrying the haptoglobin 2-2 genotype have decreased affinity to Hb and are at a higher risk of developing cerebral aneurysm-related complications due to impaired anti-inflammatory pathways. This highlights haptoglobin as part of the Hb scavenging mechanism, which may be critical for clearing Hb after intracranial bleeding and neuroprotection.Product Details
