Insights

Apoptosis, or programmed cell death, is crucial for ocular surface regulation and healing. Understanding its role in conditions like refractive surgery and toxic drug effects can improve patient outcomes.

Area of Science:

  • Ophthalmology
  • Cell Biology
  • Molecular Biology

Context:

  • Apoptosis, or programmed cell death, is a fundamental biological process.
  • While extensively studied in the retina, apoptosis significantly impacts the anterior segment and ocular surface.
  • Keratocyte apoptosis is a rapid event post-excimer refractive surgery, with epithelial damage triggering deep keratocyte death.

Purpose:

  • To explore the role of apoptosis in the anterior segment of the eye.
  • To investigate the mechanisms underlying keratocyte apoptosis after refractive surgery.
  • To understand the interplay between inflammation and apoptosis in ocular surface conditions.

Summary:

  • Epithelial aggression post-refractive surgery initiates mechanisms leading to deep keratocyte apoptosis.
  • Mediators from epithelial cells may explain LASIK's superior functional rehabilitation over PRK.
  • Inflammation and apoptosis are intertwined in the conjunctiva, with proinflammatory cytokines amplifying immune responses and stimulating epithelial apoptosis.
  • Toxic drugs can induce iatrogenic apoptosis, highlighting the need to avoid preservatives in ophthalmic preparations due to their proinflammatory and proapoptotic properties.

Impact:

  • Understanding these apoptotic pathways can lead to improved surgical techniques and patient recovery.
  • Identifying proapoptotic and proinflammatory agents in eye drops can help in developing safer formulations.
  • This research contributes to managing ocular surface pathologies and improving visual rehabilitation post-surgery.

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.
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...
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...
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...
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.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and pro-apoptotic...
