Summary
Liver cirrhosis, the end stage of chronic liver disease, involves fibrosis. Key cellular players and molecular pathways, including microRNAs (miRNAs), drive its progression, offering therapeutic targets.
Area of Science:
- Hepatology
- Cell Biology
- Molecular Biology
Background:
- Liver cirrhosis is the end-stage pathology of chronic liver diseases.
- Liver fibrosis, the precursor to cirrhosis, involves complex cellular and molecular interactions.
- Understanding these mechanisms is crucial for developing effective treatments.
Purpose of the Study:
- To review the cellular and molecular factors involved in liver fibrosis and cirrhosis.
- To highlight the pivotal role of hepatic stellate cell activation.
- To emphasize the significance of microRNAs in disease progression.
Main Methods:
- Literature review of cellular and molecular mechanisms in liver fibrosis and cirrhosis.
- Analysis of signaling pathways regulating hepatic stellate cell activation and fibrogenesis.
- Examination of the role of microRNAs in post-transcriptional regulation.
Main Results:
- Hepatic stellate cell activation is central to fibrosis development.
- Liver sinusoidal endothelial cell dysfunction and Kupffer cell activation contribute to cirrhosis.
- MicroRNAs are key post-transcriptional regulators in fibrosis and cirrhosis.
Conclusions:
- Identifying critical cellular and molecular factors is essential for therapeutic development.
- Robust animal models are vital for studying liver fibrosis and cirrhosis.
- Targeting identified pathways and miRNAs may lead to novel therapeutic strategies.

01:24Cirrhosis II: Pathophysiology
34
Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to...

01:23Cirrhosis I: Introduction
26
Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

01:25Hepatitis
80
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

4.1K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

01:22Portal Hypertension
44
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
