Autophagy is a catabolic transport route conserved among all eukaryotes that allow the degradation of large portions of the cytoplasm, protein aggregates, excess or damaged organelles and invading pathogens.

Autophagy is a catabolic process highly conserved among eukaryotes, which is involved in the degradation of long-lived proteins, aberrant complexes and aggregates, dysfunctional and superfluous organelles, and intracellular pathogens. Structures targeted to destruction are sequestered by double-membrane vesicles called autophagosomes and delivered to lysosomes for turnover. The resulting metabolites are reused by the cell as either an energy source or building blocks for the synthesis of new macromolecules.
Autophagy is essential to maintain cellular and organismal homeostasis because involved in the adaptation to stresses, quality control, metabolism regulation, cell development and differentiation, stemness maintenance, type II program cell death, tumor suppression and immunity. As a result, the impairment or defect in autophagy leads to severe pathologies such as neurodegeneration, myopathies, chronic inflammations, and some malignancies. Crucially, it has also been shown that autophagy is an effective therapy to prevent or cure diseases, including specific types of tumors, muscular dystrophies, and neurodegenerative disorders. The 2016 Nobel Prize in Medicine or Physiology to Prof. Ohsumi, a leading scientist in the field, underlines the recognized importance of autophagy in medical and life sciences.
The elucidation of the mechanisms involved in activation and regulation of autophagy, but also the identification of the proteins required for recognition and elimination of the various autophagic cargoes, is therefore of primary relevance. Understanding the exact role of autophagy in the various physiological situations and pathological conditions is also crucial. All this knowledge combined is essential to be able to modulate autophagy to the benefit of human health, but also for biotechnological and agricultural applications.
The laboratory has two major research lines. In the first, we aim in unveiling the regulation and molecular mechanism of autophagy, and for these studies, we use yeast Saccharomyces cerevisiae as a model system. As the long-term objective is to understand the exact contribution of autophagy in specific physiological and pathological contexts, the goal of the second research line has been to understand the interaction between autophagy and pathogens, in particular viruses. In doing this, our interests have also moved to the characterization of unconventional, not autophagy-linked, function of the autophagy proteins.
