Murine β-defensin 3 (mBD-3, an orthologue of hBD-2) contributes to the clearance of P. aeruginosa in vivo and additionally limits P. aeruginosa adhesion to the corneal epithelial surface, thus suggesting that AMPs are also involved in maintaining normal resistance to infection in the healthy tissues (Augustin et al., 2011). This evidence concerns the gene ADSL and infection.
