Insights

Macrophages regulate blood vessel growth in the eye. This review explores their role in retinal diseases like diabetic retinopathy and age-related macular degeneration, highlighting their importance in ocular angiogenesis.

Area of Science:

  • Ophthalmology
  • Immunology
  • Vascular Biology

Background:

  • Abnormal blood vessel formation (angiogenesis) is central to retinal diseases.
  • Conditions like retinopathy of prematurity, diabetic retinopathy, and age-related macular degeneration involve aberrant ocular angiogenesis.
  • Macrophages, part of the innate immune system, are increasingly recognized for their role in regulating this process.

Purpose of the Study:

  • To review the critical role of macrophages in regulating angiogenesis within the retina and choroid.
  • To consolidate current understanding of macrophage involvement in ocular vascular diseases.

Main Methods:

  • Literature review of recent evidence on macrophages and ocular angiogenesis.
  • Focus on studies investigating the interplay between macrophages and blood vessel development in the eye.

Main Results:

  • Macrophages are key regulators of both normal and abnormal angiogenesis in the retina and choroid.
  • Evidence implicates macrophages in the pathophysiology of major blinding retinal diseases.

Conclusions:

  • Macrophages are crucial players in ocular angiogenesis.
  • Targeting macrophage function represents a potential therapeutic strategy for retinal vascular diseases.

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Inflammatory Response01:28

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
