01 /What it is
hBD-2 (human beta defensin 2) is a 41 amino acid antimicrobial peptide encoded by the DEFB4A gene and produced by epithelial cells (skin, airway, gut) in response to bacterial and inflammatory signals. It is studied as a research compound across innate immune research and barrier biology research.
02 /How it works
In research models, hBD-2 disrupts bacterial membranes through a cationic amphipathic mechanism and signals to immune cells through CCR6 receptor binding, which links it to both direct antimicrobial activity and adaptive immune coordination. The defensin family that hBD-2 sits in is one of the oldest documented innate defense systems.
03 /What researchers explore it for
Researchers have explored hBD-2 in antimicrobial research, in innate immune research, and in epithelial barrier research.
04 /Safety and interactions
hBD-2 is for laboratory research use only and is not for human consumption. Not medical advice. Not intended to diagnose, treat, cure, or prevent any disease.
05 /Research notes
Peptide family: beta defensin family antimicrobial peptides. Frequently compared with LL-37 and Lactoferrin in innate immune research and with Magainin II in cross species defensin research. The Apothify library lists hBD-2 for encyclopedia coverage only.
