Insights

Autoimmune diseases involve genetic and environmental factors, with apoptotic cell death pathways playing a key role in their development and progression. Understanding apoptosis is crucial for autoimmune disease research.

Area of Science:

  • Immunology
  • Cell Biology
  • Pathology

Background:

  • Autoimmune diseases arise from complex interactions between genetic predisposition, environmental triggers, and random events.
  • Emerging research highlights the critical involvement of programmed cell death (apoptosis) in the initiation, propagation, and susceptibility to autoimmune disorders.
  • Apoptosis, a highly regulated cellular process, shares complexity with autoimmunity, involving multiple signaling pathways and gene products.

Purpose of the Study:

  • To elucidate the multifaceted role of apoptotic cell death pathways in the pathogenesis of autoimmune diseases.
  • To explore how apoptosis influences immune repertoire shaping and immune regulation.
  • To investigate apoptosis as both a source of tolerogens and a target in autoimmune responses.

Main Methods:

  • Review and synthesis of recent studies on apoptosis and autoimmunity.
  • Analysis of the molecular mechanisms linking apoptotic pathways to immune cell function.
  • Examination of the role of apoptosis in lymphocyte selection and immune homeostasis.

Main Results:

  • Apoptotic cell death pathways are implicated in initiating and propagating autoimmune diseases.
  • Apoptosis can serve as a source of tolerogens, influencing immune tolerance.
  • Apoptosis is essential for lymphocyte selection and immune regulation, and is also a consequence of immune responses.

Conclusions:

  • Apoptosis is intrinsically linked to the development and progression of autoimmune diseases.
  • Dysregulation of apoptotic pathways contributes to the loss of self-tolerance and autoimmunity.
  • Targeting apoptotic pathways may offer novel therapeutic strategies for autoimmune conditions.

Apoptosis01:30

Apoptosis

Apoptosis is a combination of two Greek words, 'apo' and 'ptosis,' meaning separation and falling off, respectively. Hippocrates used this word to describe gangrene, which was caused due to bandaging of fractured bones. Apoptosis was distinguished from necrosis in 1970 when John Kerr reported observations of morphological changes occurring during apoptosis. During one experiment, he observed that the disruption of blood supply to the liver tissue resulted in a size reduction of the tissue.
Cellular Injury V: Apoptosis and Autophagy01:22

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...
Autophagic Cell Death01:18

Autophagic Cell Death

Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

Autoimmune Disorders01:29

Autoimmune Disorders

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

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.
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...
