Summary
Fine particulate matter (FPM) poses health risks through cell death pathways. Further research is needed to understand FPM components and signaling interactions for better disease prevention and public health policies.
Area of Science:
- Environmental Health
- Toxicology
- Cell Biology
Background:
- Fine particulate matter (FPM) exposure is linked to significant health concerns.
- Existing research details FPM's cytotoxicity and cell death induction.
- Knowledge gaps persist regarding FPM's complex health effects.
Purpose of the Study:
- To review current knowledge gaps in FPM-induced cell death research.
- To identify challenges in attributing FPM's toxicity to specific components.
- To propose future research directions for public health policy and risk assessment.
Main Methods:
- Literature review of studies on FPM cytotoxicity and cell death pathways.
- Analysis of challenges in pollutant identification and pathway crosstalk.
- Synthesis of current data to propose future research avenues.
Main Results:
- FPM contains undefined components (heavy metals, PAHs, pathogens) complicating toxicity assessment.
- Interplay among cell death pathways hinders precise risk determination.
- Significant knowledge gaps remain in understanding FPM's adverse outcome pathways.
Conclusions:
- Addressing knowledge gaps in FPM-induced cell death is crucial for public health.
- Future research should focus on delineating pollutant roles and pathway interactions.
- Improved understanding will inform policy for FPM disease prevention and risk management.

01:17The Extrinsic Apoptotic Pathway
6.5K
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...

01:30Overview 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...

01:31The Intrinsic Apoptotic Pathway
6.7K
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...

01:46Electron Transport Chain: Complex I and II
14.6K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

01:30Apoptosis
11.7K
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...

01:27Cytotoxic T Cells-mediated Immune Response
1.0K
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...
