Insights

Pemphigus, an autoimmune skin disease, involves autoantibodies causing cell-cell adhesion loss. Apoptosis, programmed cell death, plays a key role in blister formation and may offer new treatment targets.

Area of Science:

  • Immunodermatology
  • Cell Biology
  • Pathophysiology

Background:

  • Pemphigus is a rare autoimmune blistering disease.
  • Autoantibodies target desmogleins, leading to acantholysis (loss of cell-cell adhesion).
  • Apoptosis is implicated in the mechanism of IgG-induced acantholysis.

Purpose of the Study:

  • To review the literature on the role of apoptosis in pemphigus.
  • To highlight the significance of apoptosis in blister induction.
  • To identify potential therapeutic targets.

Main Methods:

  • Literature review of studies on pemphigus and apoptosis.
  • Analysis of the role of apoptotic pathways in disease pathogenesis.

Main Results:

  • Apoptosis plays a central role in pemphigus blister formation.
  • Fas ligand (FasL) is identified as a key mediator, inducing apoptosis followed by acantholysis.
  • Pro-apoptotic molecules are crucial in blister development.

Conclusions:

  • Apoptosis is integral to pemphigus pathogenesis.
  • FasL is a critical factor in pemphigus blister induction.
  • Pro-apoptotic molecules represent promising therapeutic targets for pemphigus treatment.

The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

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...
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...

Cellular Injury V: Apoptosis and Autophagy

Cells respond to damage and stress through highly coordinated processes that decide whether they survive or undergo controlled self-destruction. Two major pathways involved in this regulation are apoptosis, a type of programmed cell death, and autophagy, a survival mechanism that helps cells adapt to adverse conditions.ApoptosisApoptosis removes aged or injured cells to maintain tissue balance. During this process, the cell shrinks, chromatin condenses and fragments, and membrane-bound...
Phagocytosis of Apoptotic Cells01:17

Phagocytosis of Apoptotic Cells

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. 
Normal cells contain receptors that prevent them from being recognized by phagocytes.
Acute Pancreatitis II: Pathophysiology01:21

Acute Pancreatitis II: Pathophysiology

The pathophysiology of acute pancreatitis centers on injury to pancreatic acinar cells, which initiates a cascade of harmful intracellular events.This injury leads to premature activation of trypsinogen to trypsin in the pancreas. Trypsin then activates other digestive enzymes, such as chymotrypsin, elastase, and phospholipase A2, which begin breaking down pancreatic tissue. The resulting autodigestion causes local inflammation, tissue swelling, hemorrhage, and fat necrosis.Injured acinar cells...
Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
