概括

边缘区域B和B1细胞特异蛋白 (MZB1) 在牙周炎中被上调. 降低MZB1的调节可以减少炎症和ER压力,促进牙周组织的骨再生.

科学领域:

细胞生物学细胞生物学
免疫学免疫学免疫学
牙周病学牙周病学

背景情况:

边缘区域B和B1细胞特异蛋白 (MZB1) 与炎症反应和ER压力有关.
在慢性炎症性口腔疾病牙周炎中MZB1的作用仍然基本上未被探索.

研究的目的:

调查牙周炎中MZB1的表达特征.
阐明MZB1在牙周炎病原发生中的功能性作用.

主要方法:

转录组分析和RT-qPCR用于评估MZB1在人类牙组织中的表达.
在体外研究中使用脂聚糖 (LPS) 诱导的牙周带干细胞 (PDLSC).
通过shRNA或腺相关病毒 (AAV) 击倒MZB1的老鼠体内牙周炎模型.

主要成果:

在牙周炎组织中,MZB1被显著上调,并与炎症途径相关.
在PDLSC中MZB1的敲击减少了LPS诱导的损伤,ER压力和亡,同时增强了增殖和骨质分化.
在体内MZB1敲除改善了牙周炎症,组织破坏和功能受损.

结论:

降低MZB1的调节缓解炎症,抑制ER压力和亡,并增强牙周炎的骨质生成能力.
向MZB1为牙周炎提供了潜在的治疗策略,促进骨再生和组织平衡.

The Oral Microbiota

The Oral Microbiota

The oral microbiome includes a complex ecosystem comprising over 700 microbial species, identified through genomic sequencing and culture-based analyses to date. This community includes a core microbiome, found universally among individuals, and a variable component influenced by environmental factors such as diet, lifestyle, and host genetics. Site-specific conditions, including oxygen gradients, pH levels, and nutrient availability, determine the spatial distribution of these microorganisms...
