Abstract

A growing number of publications show that apoptosis induction is often associated with increased autophagy indicating the existence of an interplay between these two important cellular events. The simultaneous activation of both phenomena has been detected not only in experimental settings but also in vivo under physiological and pathological conditions. Despite these studies, the reciprocal influence of the two pathways in vivo has still not been completely understood. It is clear that autophagy and apoptosis are strictly interconnected, as highlighted by the finding that the two pathways share key molecular regulators. Many novel aspects of the crosstalk between apoptosis and autophagy have recently emerged showing how complex is this relationship and how critical is for the overall fate of the cell. In this mini-review we will focus on some key experiments trying to decipher as to whether autophagy contributes to apoptosis modulation in vivo.
