Summary
Regulatory T cells (Treg cells) are vital for immune tolerance. Leptin, a hormone linked to obesity, can impair Treg cell function, potentially impacting diseases and tumor progression.
Area of Science:
- Immunology
- Endocrinology
- Oncology
Background:
- Regulatory T cells (Treg cells) are essential for immune homeostasis and peripheral tolerance.
- Obesity is characterized by chronic inflammation and linked to diseases like atherosclerosis, diabetes, and cancer.
- Leptin, an adipose tissue hormone, connects metabolic disorders with immune tolerance.
Purpose of the Study:
- To discuss recent advances on the relationship between angiogenesis, leptin, and immune tolerance.
- To focus on the role of Treg cell function in these processes.
Main Methods:
- Literature review and synthesis of current research findings.
Main Results:
- Leptin negatively affects Treg cell generation and proliferation.
- Treg cells are recruited to the tumor microenvironment, promoting tolerance and angiogenesis via factors like vascular endothelial growth factor and leptin.
Conclusions:
- Leptin plays a critical role in linking metabolic status to immune regulation.
- Understanding the interplay between leptin, Treg cells, and angiogenesis is crucial for managing inflammatory diseases and cancer.

01:24Regulation of Angiogenesis and Blood Supply
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...

01:30Regulation of Food Intake
2.8K
Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

01:22PI3K/mTOR/AKT Signaling Pathway
5.2K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

03:03mTOR Signaling and Cancer Progression
3.6K
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.

01:15Receptor Downregulation in MVBs
2.0K
Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...

01:16TGF - β Signaling Pathway
7.2K
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...
