Summary
Regulatory T cells (Tregs) modulate new blood vessel formation (angiogenesis) in a context-dependent manner. Understanding Treg-angiogenesis mechanisms is key for various diseases.
Area of Science:
- Immunology
- Cell Biology
- Vascular Biology
Background:
- Regulatory T cells (Tregs) are vital for maintaining immune balance and self-tolerance.
- Tregs also play a dynamic role in angiogenesis, the formation of new blood vessels.
- Angiogenesis is essential for tissue repair but also implicated in diseases like cancer and inflammation.
Purpose of the Study:
- To review the multifaceted role of Tregs in angiogenesis.
- To elucidate the molecular mechanisms Tregs use to regulate angiogenesis.
- To explore how these mechanisms vary in health and disease.
Main Methods:
- Literature review of studies on Tregs and angiogenesis.
- Analysis of Treg-mediated pro- and antiangiogenic effects.
- Comparison of Treg functions in homeostatic versus pathological conditions.
Main Results:
- Treg influence on angiogenesis is highly tissue- and context-specific.
- Tregs can promote or inhibit blood vessel formation.
- Mechanisms of Treg-angiogenesis modulation differ between physiological and disease states.
Conclusions:
- Tregs are significant regulators of angiogenesis with dual roles.
- Understanding Treg-angiogenesis interactions is crucial for therapeutic strategies.
- Further research into context-specific mechanisms is warranted.

3.1K
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...

6.3K
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...

4.3K
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.

9.7K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

01:24T Cell Types and Functions
1.8K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

02:17The Tumor Microenvironment
7.4K
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...
