Summary
Central nervous system (CNS) angiogenesis, the growth of new blood vessels, is vital for normal development and implicated in diseases like stroke and neurodegeneration. This review explores its molecular mechanisms in both health and disease.
Area of Science:
- Neuroscience
- Vascular Biology
- Pathophysiology
Background:
- Angiogenesis, or new blood vessel formation, occurs in the central nervous system (CNS) during development and disease.
- The blood-brain barrier (BBB), crucial for CNS protection, is formed during physiological angiogenesis.
- The neurovascular unit (NVU), comprising endothelial cells, perivascular cells, and astrocytes, regulates the BBB and CNS blood flow.
Purpose of the Study:
- To discuss the molecular mechanisms of CNS angiogenesis during embryogenesis.
- To review the role of CNS angiogenesis in various pathological conditions.
- To highlight the importance of understanding CNS angiogenesis in disease.
Main Methods:
- Literature review of molecular mechanisms in CNS angiogenesis.
- Analysis of angiogenesis in physiological and pathological CNS states.
- Discussion of research emphasizing angiogenesis in CNS disorders.
Main Results:
- CNS angiogenesis is a complex process involving the NVU and BBB formation.
- Angiogenesis plays a significant role in the pathophysiology of brain tumors, ischemic stroke, arteriovenous malformations, and neurodegenerative diseases.
- Understanding these mechanisms is crucial for developing therapeutic strategies.
Conclusions:
- CNS angiogenesis is a fundamental process with implications for both normal development and disease.
- Dysregulated angiogenesis contributes to the progression of various neurological disorders.
- Further research into CNS angiogenesis mechanisms is warranted for therapeutic advancements.

6.4K
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...

2.9K
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...

2.1K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...
