It is worth nothing that EGCG, besides showing the ability to inhibit ERp57, has been reported to inhibit biofilm formation by a variety of CF pathogens55, to interfere with P. aeruginosa quorum sensing56; to limit lung colonization by Stenotrophomonas maltophilia57 and to contribute to the control of viral infections58, 59, 60, 61. This evidence concerns the gene PDIA3 and cystic fibrosis.
