Introduction
Mermaid diagram (expand to render)
The MRC Laboratory of Molecular Biology (LMB) is a world-renowned research institute in Cambridge, UK, and one of the world's leading laboratories for molecular biology and structural biology research["@lmb-website"]. Founded in 1962, the LMB has been at the forefront of scientific discovery for over six decades, with researchers having won multiple Nobel Prizes for their work in molecular biology, structural biology, and more recently, neuroscience.
The institute's expertise in structural biology and protein science has made foundational contributions to understanding the molecular mechanisms underlying neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, ALS, and prion diseases.
