Insights

Apoptosis, programmed cell death, is implicated in age-related macular degeneration (AMD) pathogenesis. Targeting apoptosis pathways may offer a novel therapeutic strategy for AMD treatment.

Area of Science:

  • Ophthalmology
  • Cell Biology
  • Pathology

Context:

  • Age-related macular degeneration (AMD) is a leading cause of vision loss.
  • The pathogenesis of AMD involves complex cellular processes.
  • Retinal pigment epithelium (RPE) cell dysfunction is a key feature in AMD.

Purpose:

  • To explore the role of apoptosis in the pathogenesis of age-related macular degeneration.
  • To investigate the connection between oxidative stress, drusen formation, and apoptosis in AMD.
  • To evaluate the potential of targeting apoptotic pathways as a therapeutic strategy for AMD.

Summary:

  • Apoptosis, or programmed cell death, is increasingly recognized as a significant factor in age-related macular degeneration (AMD).
  • Studies indicate that apoptosis in retinal pigment epithelium cells, particularly under oxidative stress, may contribute to AMD development.
  • Similarities exist between drusen formation processes and apoptosis, suggesting a link.
  • Apoptosis is also involved in choroidal neovascularization and the formation of fibrotic scars in later stages of AMD.

Impact:

  • Understanding the role of apoptosis in AMD can lead to the development of new treatments.
  • Targeting specific apoptotic pathways could offer a novel therapeutic approach to combat AMD.
  • This research highlights the potential for interventions aimed at modulating programmed cell death to preserve vision in AMD patients.

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...
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.
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...
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...
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.
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...
