Phospholipid imbalance impairs autophagosome completion

The EMBO Journal, 2022
AbstractAutophagy, a conserved eukaryotic intracellular catabolic pathway, maintains cell homeostasis by lysosomal degradation of cytosolic material engulfed in double membrane vesicles termed autophagosomes, which form upon sealing of single‐membrane cisternae called phagophores.

TREM2-dependent effects on microglia in Alzheimer\u27s Disease [PDF]

, 2018
Alzheimer’s disease (AD) is a late-onset dementia characterized by the deposition of amyloid plaques and formation of neurofibrillary tangles (NFTs) which lead to neuronal loss and cognitive deficits.

Differentiation state-specific mitochondrial dynamic regulatory networks are revealed by global transcriptional analysis of the developing chicken lens. [PDF]

, 2014
The mature eye lens contains a surface layer of epithelial cells called the lens epithelium that requires a functional mitochondrial population to maintain the homeostasis and transparency of the entire lens.

Autophagosome Maturation and Fusion

Journal of Molecular Biology, 2017
Macroautophagy, or simply autophagy, is a degradative pathway that delivers cytoplasmic components, including cytosol and organelles, to the lysosome in double-membrane vesicles called autophagosomes. This process is initiated at the pre-autophagosomal structure or phagophore assembly site and involves a number of highly conserved autophagy-related ...

Autophagosome Formation: Tracing the Source [PDF]

Developmental Cell, 2013
Although it is well appreciated that autophagy begins with phagophore formation and expansion through lipid acquisition to become the autophagosome, this process remains poorly understood, with the source of autophagosome membrane controversial. Reporting recently in Nature, Hamasaki et al.

Myc inhibition impairs autophagosome formation [PDF]

Human Molecular Genetics, 2013
Autophagy, a major clearance route for many long-lived proteins and organelles, has long been implicated in cancer development. Myc is a proto-oncogene often found to be deregulated in many cancers, and thus is an attractive target for design of cancer therapy.

Exploiting macrophage autophagy-lysosomal biogenesis as a therapy for atherosclerosis [PDF]

, 2017
Macrophages specialize in removing lipids and debris present in the atherosclerotic plaque. However, plaque progression renders macrophages unable to degrade exogenous atherogenic material and endogenous cargo including dysfunctional proteins and ...

Interaction of mycobacterium tuberculosis with the host cells: a focus in the molecular mechanism involved in trafficking and autophagy [PDF]

, 2018
Tuberculosis (TB) is an ancient disease remaining a serious health threat worldwide. It is caused by Mycobacterium tuberculosis (Mtb), an acid-fast bacilli, non-sporulated, slow-growing, immobile and aerobic.

Mechanisms of autophagosome formation

Proceedings of the Japan Academy, Series B
The formation of autophagosomes is a pivotal step in autophagy, a lysosomal degradation system that plays a crucial role in maintaining cellular homeostasis. After autophagy induction, phase separation of the autophagy-related (Atg) 1 complex occurs, facilitating the gathering of Atg proteins and organizes the autophagosome formation site, where the ...

Vesicular trafficking and autophagosome formation [PDF]

Cell Death & Differentiation, 2009
The source of the autophagosome membrane, and the formation of the autophagosome remain the most important questions for understanding autophagy. Fundamentally, the process of autophagosome formation is similar between yeast and mammalian cells and many of the proteins involved (called the autophagy-related (Atg) proteins) are known, having been first ...
