...Jana Sanchez-Wandelmer; Nicholas T. Ktistakis; Fulvio Reggiori ABSTRACT Autophagosomes are the hallmark of autophagy, but despite their central role in this degradative pathway that involves vesicle transport to lysosomes or vacuoles, the mechanism underlying their biogenesis still remains largely...
