Researchers at Case Western Reserve University discovered that harmful gut bacteria produce a modified form of glycogen that acts as an inflammatory trigger for diseases like Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD).

凱斯西儲大學的研究人員發現,有害的腸道細菌會產生一種變異形式的肝糖,這類肝糖會成為誘發肌萎縮性脊髓側索硬化症 (ALS) 以及額顳葉失智症 (FTD) 等疾病的發炎觸發因子。

For years, scientists struggled to explain why individuals with the same genetic C9orf72 mutation faced different health outcomes.

多年來,科學家們一直難以解釋為何帶有相同 C9orf72 基因突變的人,其健康結果卻大不相同。

This research supports the growing theory of the Gut-Brain Axis, shifting our view of neurodegenerative diseases from purely genetic concerns to conditions potentially manageable through the microbiome.

這項研究支持了日益受到重視的「腸腦軸線」(ㄔㄤˊㄋㄠˇㄓㄡˊㄒㄧㄢˋ)理論,將我們對神經退化性疾病的觀點,從單純的遺傳問題,轉向為可能透過微生物群進行管理的疾病。

挑戰模式

閱讀理解

What role do gut bacteria play in the development of ALS and FTD according to the study?

正確答案

They produce inflammatory glycogen that triggers immune responses in the brain.

What is meant by the term 'incomplete penetrance' in the context of the C9orf72 mutation?

正確答案

Not every person carrying the genetic mutation will necessarily develop the diseases.

Which of the following was proven effective in reducing neuroinflammation in animal models?

正確答案

Using antibiotics or dietary interventions to lower harmful bacterial sugars.

How might doctors use these findings in future medical care?

正確答案

By monitoring glycogen levels as a biomarker to identify at-risk patients.

What is the primary significance of the 'Gut-Brain Axis' concept in this research?

正確答案

The microbiome plays an active role in neurological health.
