Abstract: Human β-defensin 2 (HBD2) has been shown to interact with pathogenic bacteria and components of the mammalian innate and adaptive immune response. We describe a quick and reliable method for the production of HBD2 in Escherichia coli. HBD2 was expressed as an insoluble fusion, chemically cleaved and oxidised to give a single, folded HBD2 β-isoform. The purified peptide was analysed by high resolution mass spectrometry, displayed a well-dispersed H NMR spectrum, was a chemoattractant to HEK293 cells expressing CCR6 and acted as an antimicrobial agent against E. coli, P. aeruginosa, C. albicans and S. aureus.
