The haptoglobin genotypes have phenotypic, biochemical, and biophysical differences affecting their antioxidant and immunomodulating functional properties.
Therefore, the functional properties of the HP2 allele, such as a lower concentration of haptoglobin in circulation, a decreased antioxidant activity, a slow metabolism of Hp2-2Hb complexes (favoring the availability of iron) and promote a cytokine profile Th1 establishes a pro-oxidant microenvironment following the infectious process.
