Protein homeostasis in development and aging
We study the mechanisms that govern protein homeostasis in developmental processes and during aging using the powerful C. elegans model system
Our group is interested in protein homeostasis, or proteostasis, which corresponds to the capacity of cells and organisms to maintain the integrity of their proteome. Loss of proteostasis during aging is a major driver of cellular dysfunction, and many age-related diseases are characterized by pathological protein misfolding and aggregation. While the machineries that establish and maintain proteostasis are present in all cells, the rate of cellular aging and the phenotypes associated can greatly vary between cell types. Our research aims at understanding how proteostasis is orchestrated in different cell types in an animal.
