Summary
Autophagy plays a dual role in viral infections, with SARS-CoV-2 hijacking this cellular process. Understanding this interplay is key to developing new COVID-19 treatments.
Area of Science:
- Cellular Biology
- Virology
- Immunology
Background:
- Autophagy is a fundamental cellular process crucial for cell survival.
- The role of autophagy in viral infections, including COVID-19, is complex, acting as both a host defense and a viral replication facilitator.
- Viruses have evolved mechanisms to manipulate the autophagy pathway for their own benefit.
Purpose of the Study:
- To review the intricate relationship between autophagy and viral infections, with a specific focus on SARS-CoV-2.
- To elucidate the mechanisms by which viruses, particularly SARS-CoV-2, modulate autophagy.
- To explore novel therapeutic strategies targeting the autophagy pathway for COVID-19 treatment.
Main Methods:
- Literature review summarizing current knowledge on autophagy and viral infections.
- Analysis of molecular mechanisms underlying autophagy modulation by viruses.
- Discussion of models for studying autophagy-virus interactions.
- Exploration of pharmacological approaches for COVID-19 treatment.
Main Results:
- Autophagy exhibits both pro-viral and anti-viral functions.
- SARS-CoV-2 actively manipulates the autophagy machinery for its replication and pathogenesis.
- The interplay between SARS-CoV-2 and autophagy involves complex molecular dynamics.
Conclusions:
- Targeting and modulating autophagy presents a promising strategy for developing effective COVID-19 treatments.
- Further research into the molecular targets and pharmacological modulation of autophagy is essential for combating COVID-19.

4.4K
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,...

3.5K
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.

01:36Delivery Pathways to the Lysosome
6.6K
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.

In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

01:13The Proteasome

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...

3.8K
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.

01:30Overview of Cell Death
7.4K
Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
