The induction of autophagy by nutrient deprivation leads to a rapid increase in the formation of autophagosomes, unique organelles that replenish the cellular pool of nutrients by sequestering cytoplasmic material for degradation. The urgent need for membranes to form autophagosomes during starvation to maintain homeostasis leads to a dramatic rearrangement of intracellular membranes. Here we discuss recent findings that have begun to uncover how different parts of the secretory pathway directly and indirectly contribute to autophagosome formation during starvation.
