Summary
Endothelial STING maintains brain metabolic homeostasis, crucial for oligodendrocyte precursor cell development and myelination. Disrupting this pathway impairs oligodendrocyte development and causes behavioral issues.
Area of Science:
- Neuroscience
- Developmental Biology
- Cell Biology
Background:
- Oligodendrocyte precursor cells (OPCs) utilize developing blood vessels for migration in the central nervous system.
- Regulatory mechanisms governing OPC proliferation and oligodendrocyte development remain largely unknown.
Purpose of the Study:
- To investigate the correlation between developing vasculature and OPC responses during brain development.
- To elucidate the role of endothelial stimulator of interferon genes (STING) in OPC regulation and oligodendrocyte development.
Main Methods:
- Investigated the effects of endothelial STING deletion on angiogenesis, cholesterol synthesis, and interleukin 17D production.
- Assessed the impact of endothelial cell metabolic perturbation on OPCs, oligodendrocyte development, myelination, and adult mouse behavior.
Main Results:
- Endothelial STING deletion disrupts angiogenesis by inhibiting farnesyl-diphosphate farnesyltransferase 1 (FDFT1), reducing cholesterol synthesis.
- Perturbed endothelial cell metabolic homeostasis increases interleukin 17D, inhibiting oligodendrocyte development and myelination.
- STING disruption leads to behavioral abnormalities in adult mice.
Conclusions:
- Endothelial STING is vital for maintaining metabolic homeostasis in the developing brain.
- Endothelial STING signaling influences oligodendrocyte precursor cell response, impacting oligodendrocyte development and myelination.

01:15Neurogenesis and Regeneration of Nervous Tissue
750
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...

01:25Nervous Tissue: Myelin
2.5K
The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...

2.5K
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...

2.8K
Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.

Hemangioblasts are multipotent stem cells originating from the mesoderm. They give rise to hematopoietic stem cells (HSCs), which undergo hematopoiesis to produce all the formed elements of blood. This process is regulated by a complex network of hematopoietic growth factors, including transcription factors, growth factors, and cytokines. These factors stimulate the HSCs to divide and differentiate, though some HSCs remain undifferentiated to maintain a self-renewing pool.
