Insights

Nonalcoholic fatty liver disease (NAFLD) is common globally. This review explores cell death and inflammation as therapeutic targets for advanced nonalcoholic steatohepatitis (NASH) with liver fibrosis.

Area of Science:

  • Hepatology
  • Immunology
  • Cell Biology

Background:

  • Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver condition worldwide.
  • Advanced stages, including nonalcoholic steatohepatitis (NASH) with liver fibrosis, cause significant morbidity and mortality.
  • Current therapeutic options for advanced NAFLD are limited.

Purpose of the Study:

  • To review the role of cell death pathways in the pathogenesis of fibrotic NASH.
  • To examine the contribution of sterile inflammatory pathways to disease progression.
  • To identify novel therapeutic targets within these pathways for treating fibrotic NASH.

Main Methods:

  • Literature review focusing on cell death mechanisms (e.g., apoptosis, necroptosis).
  • Analysis of sterile inflammation mediators and pathways (e.g., inflammasomes, DAMPs).
  • Examination of the interplay between cell death, inflammation, and fibrosis in NASH.

Main Results:

  • Cell death pathways contribute to liver injury and inflammation in NASH.
  • Sterile inflammatory responses exacerbate liver damage and promote fibrogenesis.
  • These pathways form a self-perpetuating cycle driving disease progression.

Conclusions:

  • Targeting cell death and sterile inflammation pathways offers promising therapeutic strategies for fibrotic NASH.
  • Interventions aimed at disrupting these pathways could mitigate liver fibrosis and improve patient outcomes.
  • Further research into these mechanisms is crucial for developing effective treatments for advanced NAFLD.

Liver Regeneration01:24

Liver Regeneration

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...

The Extrinsic Apoptotic Pathway01:17

The Extrinsic Apoptotic Pathway

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...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...
