Cystic Fibrosis: Pathogenesis01:23

Cystic Fibrosis: Pathogenesis

746
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Cystic Fibrosis: Management

489
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Liver Histology01:27

Liver Histology

4.2K
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...

Liver Physiology01:30

Liver Physiology

3.6K
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...

Liver Regeneration01:24

Liver Regeneration

4.3K
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...

Gross Anatomy of the Liver01:17

Gross Anatomy of the Liver

2.0K
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is...

Background:

  • Fibrosis is a universal wound-healing response to injury, common across multiple organs including the liver, lungs, and kidneys.
  • The liver serves as a key model for studying inflammation and repair due to frequent clinical biopsies.
  • Immune mechanisms driving liver injury are shared across diverse etiologies and organ systems.

Purpose of the Study:

  • To review the association between Interferon (IFN)-lambda and tissue inflammation and fibrosis in human diseases.

Main Methods:

  • Literature review of studies investigating fibrosis and inflammation.
  • Analysis of research on IFNL3/4 polymorphisms and IFN-lambda levels.
  • Examination of data linking IFN-lambda to fibrotic conditions in various organs.

Main Results:

  • IFNL3/4 polymorphisms and IFN-lambda levels are established determinants of hepatic inflammation and fibrosis.
  • These genetic factors and protein levels also correlate with fibrosis severity in nonhepatotropic viral diseases.
  • Evidence shows a correlation between IFNL3/4 polymorphisms, IFN-lambda levels, and fibrosis extent in lung and kidney tissues.

Conclusions:

  • IFN-lambda plays a significant role in modulating tissue inflammation and fibrosis across different human diseases.
  • IFNL3/4 polymorphisms and IFN-lambda levels are critical factors influencing fibrotic disease progression.
  • Understanding these associations may offer potential clinical applications for managing fibrotic disorders.
