Upregulated expression of human alpha-defensins 1, 2 and 3 in hypercholesteremia and its relationship with serum lipid levels

Human alpha-defensins are natural antimicrobial peptides of neutrophils evolved in host defense reactions and circulating nonstressed alpha-defensins may be associated with serum lipid levels. The aim of this work was to examine whether the expression of alpha-defensins 1, 2 and 3 genes are changed and whether this changes are reversed following treatment in patients with hypercholesteremia. A total of 40 individuals of hypercholesteremia group were studied, compared with 40 individuals of normal control group. Protein levels and gene expression levels of alpha-defensins 1, 2 and 3 were significantly higher in patients with hypercholesteremia compared with subjects in normal control group. In patients with hypercholesteremia, protein levels of alpha-defensins 1, 2 and 3 correlated positively with the levels of total cholesterol and low-density lipoprotein cholesterol. Protein levels and gene expression levels of alpha-defensins 1, 2 and 3 were decreased significantly after a treatment with atorvastatin calcium 20 mg daily compared with the patients before the treatment. Our results suggest that the expression of alpha-defensins 1, 2 and 3 genes is involved in dyslipidemia in patients with hypercholesteremia.
