Chez les mammifères, les carences nutritionnelles telles que les carences en acides aminés constituent un stress nutritionnel important. Pour faire face à ces situations, l'organisme dispose de processus adaptatifs tels que l'autophagie, régulés par de multiples voies de signalisation. Au niveau cellulaire, plusieurs voies de signalisation sont impliquées dans la régulation de ces processus adaptatifs qui permettent la survie cellulaire lors de différentes conditions de stress environnementaux y compris la carence en acides aminés. En particulie,r la voie eIF2α/ATF4 joue un rôle crucial dans l'adaptation des cellules à ces différents stress notamment en régulant la transcription de nombreux gènes cibles spécifiques.
