Liver Regeneration

3.3K
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...

Liver Physiology01:30

Liver Physiology

600
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Diseases of the Liver and Gallbladder

597
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...

Liver Histology01:27

Liver Histology

855
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Introduction to Fibroblasts01:09

Introduction to Fibroblasts

3.1K
Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...

Area of Science:

  • Hepatology and Gastroenterology
  • Molecular Biology
  • Drug Discovery

Background:

  • Liver fibrosis is a significant global health issue, often resulting from chronic viral or chemical liver diseases.
  • Collagen deposition is central to liver fibrosis progression and the development of hepatocellular carcinoma (HCC).
  • While triggers for liver fibrosis can be eliminated, reversing established fibrosis, especially severe cases, remains challenging, highlighting the need for effective anti-fibrotic therapies.

Purpose of the Study:

  • To provide an overview of the physiological and molecular origins of collagen in chronic liver disease.
  • To explore how these collagen-related mechanisms influence the development of anti-fibrotic treatments.
  • To address the urgent need for effective anti-fibrotic medications to prevent liver damage and HCC.

Main Methods:

  • Review of existing literature on liver fibrosis pathogenesis.
  • Analysis of the role of collagen in chronic liver disease.
  • Investigation of current and emerging anti-fibrotic treatment strategies.

Main Results:

  • Collagen plays a critical role in the development and progression of liver fibrosis and HCC.
  • Existing anti-fibrotic drug candidates have shown limited efficacy in human studies despite promising results in animal models.
  • There is currently no approved drug specifically for treating liver fibrosis.

Conclusions:

  • Understanding the molecular basis of collagen synthesis and deposition in liver fibrosis is crucial for developing targeted therapies.
  • The limited success of current anti-fibrotic treatments underscores the need for novel therapeutic approaches.
  • Further research into anti-fibrotic mechanisms is essential to combat liver fibrosis and reduce the incidence of HCC.
