Summary
Lipocalins, proteins involved in cell death, have shown varied effects on apoptosis. This review focuses on lipocalin-2
Area of Science:
- Cellular biology
- Molecular biology
- Biochemistry
Background:
- Cell survival and apoptosis are critical processes altered by various stressors.
- The lipocalin protein family is known to influence apoptosis.
- Previous studies show conflicting pro- and anti-apoptotic roles for lipocalins.
Purpose of the Study:
- To review existing literature on lipocalins and apoptosis.
- To explore the specific role of lipocalin-2 in cell death and survival pathways.
Main Methods:
- Literature review and synthesis of existing studies.
- Analysis of research on lipocalin family members and their impact on apoptosis.
- Focus on studies investigating lipocalin-2's function.
Main Results:
- Lipocalins exhibit diverse effects on apoptosis, acting as both inducers and inhibitors.
- Evidence suggests lipocalin-2 plays a significant role in modulating cell death.
- The precise mechanisms of lipocalin-2 in cell survival and apoptosis require further elucidation.
Conclusions:
- Lipocalins are key regulators of apoptosis with context-dependent functions.
- Lipocalin-2 emerges as a critical factor in the balance between cell survival and death.
- Further research is warranted to fully understand lipocalin-2's therapeutic potential in diseases involving apoptosis.

01:17Phagocytosis of Apoptotic Cells
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.
Normal cells contain receptors that prevent them from being recognized by phagocytes.

01:17The Extrinsic Apoptotic Pathway
The extrinsic apoptotic pathway is initiated when extracellular death-inducing signals, such as specific cytokines, activate the death receptors expressed on the cell surface. The immune cells involved in this pathway are natural killer cells (NK cells) and cytotoxic T-lymphocytes. NK cells are critical in innate immune response, while cytotoxic T-lymphocytes are associated with adaptive immune response. These cells recognize specific receptors expressed on the altered cells and activate...
01:31The Intrinsic Apoptotic Pathway
Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
01:30Apoptosis
Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
01:22Cellular Injury V: Apoptosis and Autophagy
Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
01:18Autophagic Cell Death
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.
