Summary
Epigenetic dysregulation, including DNA methylation and histone modifications, plays a key role in vitiligo pathogenesis. These epigenetic changes offer potential as biomarkers and therapeutic targets for this chronic skin depigmentation disorder.
Area of Science:
- Dermatology
- Genetics
- Epigenetics
Background:
- Vitiligo is a chronic depigmentary disorder caused by melanocyte loss.
- Its development involves genetic, environmental, and autoimmune factors.
- Epigenetic mechanisms are increasingly recognized as crucial in vitiligo.
Purpose of the Study:
- To review the role of epigenetic dysregulation in vitiligo pathogenesis.
- To explore the translational implications of these epigenetic alterations.
- To provide a foundation for novel therapeutic strategies.
Main Methods:
- Systematic review of molecular mechanisms.
- Analysis of epigenetic alterations in vitiligo.
- Evaluation of translational potential for diagnostics and therapeutics.
Main Results:
- Aberrant DNA methylation, histone modifications, and ncRNA disturbances are implicated.
- Epigenetic changes disrupt melanogenesis, promote melanocyte apoptosis, and drive autoimmunity.
- Specific epigenetic markers show potential for diagnosis and monitoring treatment response.
Conclusions:
- Epigenetic dysregulation is central to vitiligo pathogenesis.
- Epigenetic therapies, including drug treatments and gene editing, show promise.
- Understanding epigenetic mechanisms is key to advancing vitiligo treatment.

The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

3.7K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

4.1K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
