Modeling Membrane Morphological Change during Autophagosome Formation [PDF]
iScience, 2020 Summary: Autophagy is an intracellular degradation process that is mediated by de novo formation of autophagosomes. Autophagosome formation involves dynamic morphological changes; a disk-shaped membrane cisterna grows, bends to become a cup-shaped ...

Autophagosome formation in relation to the endoplasmic reticulum [PDF]
Journal of Biomedical Science, 2020 Autophagy is a process in which a myriad membrane structures called autophagosomes are formed de novo in a single cell, which deliver the engulfed substrates into lysosomes for degradation.

Phosphatidylinositol-4-phosphate controls autophagosome formation in Arabidopsis thaliana [PDF]
Nature Communications, 2022 Autophagosomes are specialized vesicles that target and deliver cargo to the lytic vacuole. Here the authors show that plasma-membrane derived lipid phosphatidylinositol-4-phosphate supports the assembly and expansion of autophagosomes in ...

In situ structural analysis reveals membrane shape transitions during autophagosome formation [PDF]
Proc Natl Acad Sci U S A, 2022 Autophagosomes are unique organelles which form de novo as double-membrane vesicles engulfing cytosolic material for destruction. Their biogenesis involves a series of membrane transformations with distinctly shaped intermediates whose ultrastructure is ...

A novel autophagy inhibitor, bTBT, disturbs autophagosome formation [PDF]
Autophagy Reports, 2023 Macroautophagy (hereafter, autophagy) is a form of intracellular degradation in which autophagosome formation is systematically coordinated by multiple processes involving numerous autophagy-related gene (ATG) proteins. Autophagy-modulating compounds are

An initial step of GAS-containing autophagosome-like vacuoles formation requires Rab7. [PDF]
PLoS Pathogens, 2009 Group A streptococcus (GAS; Streptococcus pyogenes) is a common pathogen that invades non-phagocytic human cells via endocytosis. Once taken up by cells, it escapes from the endocytic pathway to the cytoplasm, but here it is contained within a membrane ...

SEC31a‐ATG9a Interaction Mediates the Recruitment of COPII Vesicles for Autophagosome Formation [PDF]
Advanced ScienceAutophagy plays an important role in determining stem‐cell differentiation. During the osteogenic differentiation of mesenchymal stem cells (MSCs), autophagosome formation is upregulated but the reason is unknown.

Fluorescence Microscopy Analysis of Drug Effect on Autophagosome Formation [PDF]
Bio-Protocol, 2014 The autophagy protein, LC3 represents a reliable characteristic marker for autophagosomal structures. The initial LC3 is processed by the cysteine protease autophagy-related gene 4 (Atg4) at its C terminus in order to create LC3-I generally localized in ...
