HD5

Catalog No.: A42409
Bioactive Peptide
HD5 is a bioactive peptide derived from human defensin-5, exhibiting lectin-like properties. Secreted by Paneth cells in the crypts of Lieberkuhn, HD5 interacts with glycosylated proteins and lipid components, playing a crucial role in mucosal immunity. Importantly, HD5 is known to competitively inhibit ACE2 receptors on host cells, thereby providing a mechanism to reduce SARS-CoV-2 infection. This peptide has applications in studying antiviral mechanisms and innate immune responses.
