Summary
Zinc is crucial for skin health, particularly epidermal keratinocyte function. Zinc deficiency causes disorders like acrodermatitis enteropathica, characterized by alopecia, diarrhea, and skin lesions.
Area of Science:
- Dermatology
- Human Physiology
- Molecular Biology
Background:
- Skin possesses the third highest zinc concentration among all tissues.
- Zinc is essential for epidermal keratinocyte proliferation and differentiation.
- Zinc homeostasis is vital for maintaining skin integrity and function.
Purpose of the Study:
- To review the dynamics and functions of zinc in the skin.
- To explore skin disorders linked to zinc deficiency, zinc-binding proteins, and transporters.
- To elucidate the mechanisms behind zinc deficiency-related skin conditions.
Main Methods:
- Literature review of zinc's role in skin biology.
- Analysis of genetic mutations affecting zinc transport (e.g., ZIP4 transporter).
- Examination of clinical manifestations and underlying pathology of zinc deficiency disorders.
Main Results:
- Acrodermatitis enteropathica, caused by ZIP4 mutations, results in alopecia, diarrhea, and characteristic skin lesions.
- Zinc deficiency is implicated in conditions such as alopecia and necrolytic migratory erythema.
- New findings highlight mechanisms of acrodermatitis development due to zinc deficiency.
Conclusions:
- Zinc plays a critical role in skin health and epidermal function.
- Disorders of zinc transport and homeostasis lead to significant dermatological conditions.
- Understanding zinc's role is key for diagnosing and managing these skin diseases.

01:23Role of Skin in Vitamin D Synthesis
8.6K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

01:27The Skin Microbiota
13
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...

01:19Pigmentation
4.9K
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...

4.1K
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.

01:27Acne Infection

Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

01:21Accessory Structures of the Skin: Sebaceous Glands
5.2K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...
