研究疾病: |
重症肌无力 (MG) 是一种慢性自身免疫性疾病,其特征在于,在很大一部分患者的神经肌肉接头 (NMJ) 处存在针对AChR)的血清自身抗体;AChR特异性抗体导致NMJ的改变和破坏,引起局部或全身的异常肌肉无力和易疲劳,这是MG的主要临床症状。 |

|
Target disease: |
Myasthenia Gravis (MG) is a chronic autoimmune disease characterized by the presence of serum autoantibodies against the nicotinic acetylcholine receptor (AChR) at the neuromuscular junction (NMJ) in a large proportion of patients; AChR-specific antibodies lead to the alteration and destruction of NMJ causing partial or systemic abnormal muscle weakness and fatigability, major clinical symptoms in |

研究目的: |
本研究中我们将收集至少40例抗AchR抗体阳性MG患者(其中OMG组至少20例,GMG组至少20例)的唾液样本,通过16S rDNA测序及生物信息学分析比较两组之间唾液菌群及代谢通路的差异,寻找能够预测分型转化的生物学标志物,以进一步探讨MG发病及分型转化的机制,为寻找早期精准治疗的新靶点提供依据。 |
||||||||||||||||||||||
|
Objectives of Study: |
In this study, we will collect saliva samples from 38 MG patients positive for anti-ACHR antibody (including 19 cases in the OMG group and 19 cases in the GMG group). Through 16S rDNA sequencing and bioinformatics analysis, we will compare the differences in saliva microbiota and metabolic pathways between the two groups to search for biological markers that can predict typing transformation. To further explore the mechanism of the onset and classification transformation of MG, and to provide a basis for finding new targets for early and precise treatment. |
