Background/aims: Autoinducer-2 (AI-2) is used by several bacteria in quorum-sensing signaling and is a product of LuxS. The aim was to investigate the effect of LuxS mutation on expression of Streptococcus intermedius vir...
Role of gap3 in Fap1 glycosylation, stability, in vitro adhesion, and fimbrial and biofilm formation of Streptococcus parasanguinis [0.03%]
Gap3在副血链球菌Fap1糖基化、稳定性、体外粘附力及菌毛和生物被膜形成中的作用
Z Peng,H Wu,T Ruiz et al.
Z Peng et al.
Background/aims: Streptococcus parasanguinis is a primary colonizer of the tooth surface. Its adhesion is mediated by the long fimbriae, which are composed of multiple subunits of a serine-rich glycoprotein, Fap1. Previou...
Biological properties of the native and synthetic lipid A of Porphyromonas gingivalis lipopolysaccharide [0.03%]
牙龈卟啉单胞菌脂多糖天然和合成的脂质A的生物学性质

Introduction and methods: A pentaacyl and diphosphoryl lipid A molecule found in the lipid A isolated from Porphyromonas gingivalis lipopolysaccharide (LPS) was chemically synthesized, and its characteristics were evaluat...
Relationship between Campylobacter rectus and periodontal status during pregnancy [0.03%]
妊娠期牙周状况与Campylobacter rectus的关系
M Yokoyama,D Hinode,M Yoshioka et al.
M Yokoyama et al.
Introduction: In a previous study, we showed that the growth of Campylobacter rectus is stimulated by the presence of female sex hormones in the culture medium. In the present study, we examined the relationship between C...
Characterization of CD4+ FOXP3+ T-cell clones established from chronic inflammatory lesions [0.03%]
慢性炎症病灶中建立的CD4+FOXP3+T细胞克隆的性质分析
T Okui,H Ito,T Honda et al.
T Okui et al.
Introduction: Our previous study demonstrated that the gene expression of FOXP3, a characteristic marker for CD4(+) CD25(+) regulatory T cells in mice, is upregulated more in periodontitis than in gingivitis at the messen...
