Summary
Non-alcoholic fatty liver disease (NAFLD) involves complex molecular mechanisms, particularly apoptosis, leading to liver inflammation and fibrosis. Understanding these pathways, including lifestyle factors, is key to developing new therapies for this common condition.
Area of Science:
- Hepatology
- Molecular Biology
- Cell Death Research
Background:
- Non-alcoholic fatty liver disease (NAFLD) is a prevalent condition with limited treatment options.
- NAFLD pathogenesis involves multifactorial molecular mechanisms driving liver inflammation and fibrosis.
- Apoptosis plays a critical role in the liver injury characteristic of non-alcoholic steatohepatitis (NASH).
Purpose of the Study:
- To summarize the molecular mechanisms of non-alcoholic steatohepatitis (NASH) pathogenesis.
- To elucidate the role of apoptosis signaling in NAFLD progression.
- To explore potential clinical applications and the impact of lifestyle factors.
Main Methods:
- Review of fundamental molecular mechanisms in NAFLD.
- Focus on apoptotic signaling pathways in the liver.
- Analysis of metabolic and pathological implications of apoptosis.
- Dissection of lifestyle factors influencing NAFLD.
Main Results:
- Apoptosis derailment is central to liver injury and inflammation in NASH.
- Mitochondria integrate signals converging in apoptosis activation.
- Modifiable risk factors like obesity and alcohol impact apoptosis and NAFLD progression.
Conclusions:
- Understanding apoptosis in NAFLD offers insights into disease mechanisms.
- Integrating cell death context can guide the development of novel therapeutic strategies.
- Lifestyle modifications are crucial for managing NAFLD progression by influencing apoptosis.

01:17The Extrinsic Apoptotic Pathway
7.9K
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...

01:30Apoptosis
13.8K
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...

01:31The Intrinsic Apoptotic Pathway
8.1K
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...

01:17Phagocytosis of Apoptotic Cells
4.8K
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.

01:24Chronic Pancreatitis I: Introduction
637
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

01:24Caspases
13.6K
Caspase, a family of cysteine proteases, serve as effectors in apoptosis. The ced3 gene in C.elegans was first identified to be involved in apoptosis. This gene encodes the ced-3 caspase that is similar to the interleukin-1-beta converting enzyme or ICE in mammals. In addition to apoptosis, caspases also function in the inflammatory response. Inflammatory caspases are essential in activating pro-inflammatory cytokines that recruit immune cells and block the replication of pathogens inside...
