Microbiome of the Eye01:22

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

背景情况:

  • 眼膜粘膜皮病 (OcMMP) 是一种罕见的自身免疫性疾病,导致逐渐的结膜痕和潜在的失明.
  • 了解OcMMP的分子机制对于开发有效的治疗方法至关重要.

研究的目的:

  • 评估结节性遗传转录组分析作为研究OcMMP病原性途径的工具的可行性.
  • 为了确定关键的基因和涉及OcMMP病变的途径.

主要方法:

  • 用NanoString nCounter人类纤维化面板对6名OcMMP患者和8名对照人进行结合性RNA的分析.
  • 分析了基因表达数据 (770个基因),按可见结膜炎症分层.
  • 差异性基因表达和途径分析使用ROSALIND HyperScale架构进行.

主要成果:

  • 在OcMMP患者和对照者之间发现了93个差异表达的基因.
  • 上调的基因包括纤维化标志物 (COL3A1,COL1A1,FN1,THBS1);下调的基因表明眼表面衰竭.
  • 参与细胞外基质 (ECM) 重塑的关键通路发生了显著的改变,特别是在炎症眼睛中.

结论:

  • 结膜和NanoString技术可以在OcMMP中识别益纤维素基因.
  • 这种方法可以区分炎症眼睛,并为监测疾病进展和开发生物标志物提供潜力.
