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. 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.
¶ History and Institutional Development
¶ Origins and Founding (1947-1962)
The MRC Laboratory of Molecular Biology traces its origins to the MRC Unit for the Study of the Molecular Structure of Biological Systems, founded in 1947. Under the leadership of pioneering scientists:
- Max Perutz: Determined the structure of hemoglobin
- John Kendrew: Determined the structure of myoglobin
