This study was aimed to investigate the effects of () immunity and intestinal epithelial barrier function at the intestinal mucosal level, by using enteritidis ( enteritidis) to infect specific-pathogen-free (SPF) chickens and intestinal epithelial cells (IEC). We found that could decrease cytokine levels (IFN-γ, IL-1β, IL-8, and TNF-α) via the TLR4-, MyD88-, and NF-κB-dependent pathways in intestinal tissues and intestinal epithelial cells. Additionally, could attenuate bacteria-induced intestinal damage and increase the expression level of muc-2 and ZO-1 in the intestine and intestinal epithelial cells. Furthermore, altered the intestinal microbial composition, increased the diversity of the bacterial communities in the cecum of -infected chickens. In conclusion, effectively attenuated inflammation and epithelial barrier damage, altered the intestinal microbial composition, increased the diversity of the bacterial communities in the intestine of -infected chickens. The result suggests that might be an effective and safe therapy for the treatment of infection.
本研究旨在通过使用肠炎沙门氏菌感染无特定病原体(SPF)鸡和肠上皮细胞(IEC),在肠道黏膜水平研究()免疫和肠上皮屏障功能的影响。我们发现,()可通过肠道组织和肠上皮细胞中依赖TLR4、MyD88和NF-κB的途径降低细胞因子水平(IFN-γ、IL-1β、IL-8和TNF-α)。此外,()可减轻细菌诱导的肠道损伤,并增加肠道和肠上皮细胞中muc-2和ZO-1的表达水平。此外,()改变了肠道微生物组成,增加了感染()鸡盲肠中细菌群落的多样性。总之,()有效减轻了炎症和上皮屏障损伤,改变了肠道微生物组成,增加了感染()鸡肠道中细菌群落的多样性。结果表明,()可能是治疗()感染的一种有效且安全的疗法。
