Summary
Incomplete autophagy, an impaired cellular process, disrupts homeostasis and promotes cell death, unlike general autophagy. This review details its role in disease and potential as a therapeutic target.
Area of Science:
- Cellular Biology
- Molecular Mechanisms
- Disease Pathogenesis
Background:
- Incomplete autophagy is characterized by autophagosome accumulation without lysosomal fusion, blocking autophagic flux.
- Unlike general autophagy's dual role, incomplete autophagy consistently disrupts cellular homeostasis and induces cell death.
Purpose of the Study:
- To review the literature on incomplete autophagy over the past decade.
- To explore its molecular mechanisms, signaling pathways, and implications for human diseases and pharmacotherapy.
Main Methods:
- Comprehensive literature review of studies on incomplete autophagy.
- Analysis of molecular mechanisms and signaling pathways involved.
- Examination of disease relevance and therapeutic implications.
Main Results:
- Incomplete autophagy uniquely promotes cell death by disrupting cellular homeostasis.
- It is closely linked to the pathogenesis and progression of various human diseases.
- Pharmacological and toxicological effects of compounds are associated with incomplete autophagy.
Conclusions:
- Incomplete autophagy plays a distinct role in cellular physiology and disease.
- Targeting incomplete autophagy offers potential for developing novel therapeutic agents for diverse diseases.

4.7K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

01:36Delivery Pathways to the Lysosome
8.0K
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

01:18Autophagic Cell Death
3.6K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:22Lysosomal Hydrolases
3.9K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

01:13The Proteasome
1.2K
Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...

3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
