The phagophore in four dimensions-a study in wood.

Autophagy
John C Sewell, Daniel J Klionsky

Abstract

One of the key features of macroautophagy/autophagy is the dynamic nature of the membrane rearrangements that take place during expansion of the phagophore, the sequestering compartment that matures into an autophagosome. There are various ways to depict this process, but in most cases the method ultimately relies on a two-dimensional medium. Most people working in the field of autophagy realize that the typical 'C'-shaped drawing of a phagophore is meant to represent a cup- or bowl-like structure that exists in the cell in 3 dimensions. However, explaining this concept to a lay person often leads to confusion and misinterpretation. Accordingly, we decided to generate a four-dimensional version of the expanding phagophore as a wood sculpture, that depicts this transient compartment in 3 dimensions over time. ER: endoplasmic reticulum.

Autophagy & Aging: Inhibitors

The feed focuses on the role of nuclear export inhibitors and their effect on autophagy and the aging process.

Autophagosome

An autophagosome is the formation of double-membrane vesicles that involve numerous proteins and cytoplasmic components. These double-membrane vesicles are then terminated at the lysosome where they are degraded. Discover the latest research on autophagosomes here.

Autophagy & Model Organisms

Autophagy is a cellular process that allows degradation by the lysosome of cytoplasmic components such as proteins or organelles. Here is the latest research on autophagy & model organisms
