Summary
Osteopontin (OPN) levels are elevated in alopecia areata (AA) patients compared to controls. While DPCP treatment improved recovery, it did not significantly reduce OPN plasma levels in patients with hair loss.
Area of Science:
- Immunodermatology
- Molecular biology
- Autoimmune diseases
Background:
- Osteopontin (OPN) is a key protein in inflammation and immunity, particularly in Th1-mediated conditions.
- Alopecia areata (AA) is an autoimmune disorder with a Th1 cytokine profile, suggesting a potential role for OPN.
Purpose of the Study:
- To investigate plasma osteopontin levels in patients with alopecia areata.
- To assess changes in OPN levels before and after treatment with diphenylcyclopropenone (DPCP).
Main Methods:
- Plasma OPN levels were measured in AA patients and healthy controls.
- OPN levels were re-evaluated in AA patients who underwent DPCP treatment.
Main Results:
- Patients with alopecia areata exhibited significantly higher plasma OPN levels than healthy individuals.
- Complete recovery following DPCP treatment did not correlate with a significant reduction in plasma OPN levels.
Conclusions:
- Elevated osteopontin may be associated with the pathogenesis of alopecia areata.
- DPCP treatment efficacy in AA might not be directly linked to modulation of plasma osteopontin levels.

01:28Role of Hematopoietic Growth Factors
4.4K
Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.

4.0K
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...

01:24Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors
1.6K
Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI) tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining.

01:06Multipotency and Niche of Bulge Stem Cell
4.4K
A hair follicle or HF is a small part of the skin that produces the hair shaft. Paul Gerson Unna was the first to observe a bulge in the human hair follicle's outer root sheath (ORS). The bulge is present between the sebaceous gland and the arrector pili muscle and is the niche for hair follicle stem cells (HFSCs). The bulge is also a niche for melanocyte stem cells, and their loss results in graying of hair. The HFSCs express Sox9 and Lhx2, which help them maintain stemness and prevent...

01:01Regulation of Hematopoietic Stem Cells
4.4K
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...

03:03mTOR Signaling and Cancer Progression
5.1K
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.
