在这项研究中,我们证明了ΔCaecm33双突变体减少了生物被膜的形成,并对牙龈粘膜组织造成了较小的损害。作为凋亡标记物的坏死细胞和bax/bcl2基因表达水平的降低证实了这一点。相反,亲本菌株和Caecm33突变菌株减少了基底膜蛋白(层粘连蛋白5和IV型胶原)的产生。因此,我们认为ECM33基因/蛋白是预防和治疗念珠菌感染的新靶点。
In this study we demonstrated that ΔCaecm33 double mutant showed reduced biofilm formation and causes less damage to gingival mucosa tissues. This was confirmed by the reduced level of necrotic cells and Bax/Bcl2 gene expression as apoptotic markers. In contrast, parental and Caecm33 mutant strains decreased basement membrane protein production (laminin 5 and type IV collagen). We thus propose that ECM33 gene/protein represents a novel target for the prevention and treatment of infections caused by Candida.
