- Nanotechnology
- Toxicology
Background:
- Autophagy is a cellular degradation pathway crucial for homeostasis.
- It recycles cellular components and eliminates waste.
- Autophagy can be activated by environmental and intracellular stress.
Purpose of the Study:
- To review autophagy activation mechanisms in response to nanomaterials.
- To analyze the impact of nanomaterials on the lysosome-autophagy system.
- To discuss biocompatible and bioadverse outcomes of nanomaterial-induced autophagy.
Main Methods:
- Literature review of studies on nanomaterial-autophagy interactions.
- Analysis of cellular markers for autophagy activation.
- Evaluation of nanomaterial effects on lysosome-autophagy pathways.
Main Results:
- Nanomaterials, both natural and engineered, can activate autophagy.
- Autophagy activation by nanomaterials can lead to clearance of toxic materials or cell death.
- Specific cellular markers indicate biocompatible or bioadverse outcomes.
Conclusions:

6.1K
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
10.5K
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.

01:18Autophagic Cell Death
5.0K
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.

01:17Phagocytosis of Apoptotic Cells
5.6K
Cells undergoing apoptosis form apoptotic bodies that must be removed immediately to prevent inflammation, autoimmune diseases, and necrosis. Phagocytosis is carried out by professional phagocytes such as macrophages or immature dendritic cells. Non-professional phagocytes such as epithelial cells and fibroblasts also take part in this process; however, they are not as effective as professional phagocytes.
