🧠 破解阿茲海默症纖維蛋白生長的祕密 🧩

我們最新的研究 〈利用分子模擬探索 Abeta42 單體在纖維蛋白表面的擴散動力學〉,揭開了阿茲海默症研究中一個長久未解的謎團——β-類澱粉蛋白(Abeta)單體在纖維蛋白表面如何移動並組裝

🔍 粗粒化分子動力學模擬的關鍵發現:
1️⃣ 方向很重要:沿纖維軸平行排列的單體擴散速度遠快於垂直排列的單體。
2️⃣ 表面質地也關鍵:平滑的纖維表面促進快速移動,粗糙的區域則會減慢擴散。
3️⃣ 隱藏的能量節奏:我們發現纖維表面存在週期性的能量地形,由其表面地形與單體物理尺寸共同塑造,像賽道上的軌道一樣引導單體的運動。
4️⃣ 纖維扭曲的調控作用:纖維固有的扭曲可選擇性地影響單體方向與擴散,進而影響纖維生長速率。

💡 為什麼重要?
這些發現將我們對纖維蛋白延伸的理解,拓展到傳統「端點延伸」模型之外。透過揭示分子方向性、表面異質性能量地形的交互作用,我們提供了全新的理論觀點,並為開發延緩或抑制病理性聚集的精準治療策略帶來啟發。

🧪 這項工作連結了分子生物物理治療策略,展現奈米尺度動態如何影響疾病進程。

🙏 特別感謝我的學生 王冠方(中正化生)、陳宏毅(中正化生)、馬元偉(清華生資) —— 你們的投入與洞察讓這項研究得以實現。看到你們在研究上的成長,讓我既欣慰又驕傲。

Celebrating Our Mentor: Prof. Min-Yeh Tsai Named CCU Young Scholar! 賀蔡旻燁助理教授榮獲『中正青年學者』獎!!

We’re thrilled to share that MYTLab’s very own leader, Prof. Min-Yeh Tsai, has been honored with the prestigious “CCU Young Scholar Award”!

This award recognizes rising academic stars at National Chung Cheng University who demonstrate outstanding achievements in research, teaching, and service. Within just three years of joining CCU, Prof. Tsai has established a vibrant research program at the intersection of theoretical chemistry, molecular biophysics, and computational biology—illuminating mechanisms behind protein aggregation and gene regulation one simulation at a time.

Whether it’s decoding the complex dance of protein-DNA interactions or training the next generation of scientists, Prof. Tsai leads with vision, rigor, and heart.

“This award isn’t just mine—it’s a reflection of the incredible students, collaborators, and family that make the journey worthwhile,” says Prof. Tsai.

MYT received the award from the CCU President Prof. S.-J. Tsai.

Understanding PTM Impact on Microbial Amyloid Proteins Through Molecular Simulation

This project aims to delve into the molecular mechanisms of microbial amyloid proteins, particularly focusing on the role of post-translational modifications (PTMs) in these processes. Applying a comprehensive approach, researchers will use a transferable coarse-grained biomolecular simulation package to examine protein–protein interaction properties at interfaces. These interactions are pivotal in various microbial functions such as toxicity, signaling, and biofilm formation in plant-associated microbial communities. Researchers will integrate EMSL’s Python-based workflow with the Associative-memory, Water-mediated, Structure, and Energy Model (AWSEM) to predict protein structures and folding patterns for an intuitive analysis, especially for PTM-specific regulation.
