Ori Associated Research Group

Aging of Protein Complexes:
The Building Blocks of Our Body

Dr. Alessandro Ori has moved to Genentech, South San Francisco CA, USA  in August 2023. His group is still associated to the FLI and still working in his former lab.

The Research Group “Aging of Protein Complexes” is interested in studying how age and environmental factors affect our organs at the molecular level. The group employs ultra-sensitive approaches allowing the quantification of thousands of proteins in tissues as well as in rare cell populations. The group’s goal is to identify, in an unbiased way, functionally relevant alterations of the proteome that will enable the researchers to understand the mechanisms of organ deterioration that impact on healthy lifespan.

Aging protein modules
By studying the molecular changes that occur between young and old animals, we aim to understand what makes old organs more prone to failure and disease.
