Accessory Structures of the Skin: Hair Growth and Types

3.1K
Hair growth begins with the production of keratinocytes by the basal cells of the hair bulb. As new cells are deposited at the hair bulb, the hair shaft is pushed through the follicle toward the surface. Keratinization is completed as the cells are pushed to the skin surface to form the shaft of hair that is externally visible. The external hair is completely dead and composed entirely of keratin. Hair can be cut or shaven without damaging the hair structure because the cut is superficial. Most...

Skin Diseases and Disorders

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...

Multipotency 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...

Accessory Structures of the Skin: Hair and Hair Follicles

5.6K
Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet.
Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...

Unrenewable Cells

In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of...

Autoimmune Disorders01:29

Autoimmune Disorders

2.2K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

    Summary
    This summary is machine-generated.

    Alopecia areata (AA) is an autoimmune condition causing patchy hair loss. While genetics play a role, treatments focus on corticosteroids, with psychological support crucial for managing its impact.

    Area of Science:

    • Dermatology
    • Immunology
    • Genetics

    Background:

    • Alopecia areata (AA) is a common, non-scarring hair loss condition affecting 0.1-0.2% of the population.
    • Its etiology is believed to be a combination of genetic and autoimmune factors.
    • Genetic links include 139 single nucleotide polymorphisms in 8 genomic regions associated with T cells and hair follicles.

    Purpose of the Study:

    • To provide a comprehensive overview of alopecia areata.
    • To discuss the genetic and autoimmune underpinnings of the condition.
    • To review current and alternative treatment options for AA.

    Main Methods:

    • Clinical diagnosis is the primary method for identifying AA.
    • Genetic studies have identified numerous polymorphisms linked to AA.
    • Autoimmune markers, specifically hair follicle-specific auto-antibodies, are frequently observed in patients.

    Main Results:

    • AA has a significant genetic component with identified polymorphisms.
    • Autoimmune responses targeting hair follicles are implicated in AA pathogenesis.
    • Intralesional corticosteroids are the preferred treatment, though systemic steroids are effective but have side effects.

    Conclusions:

    • Alopecia areata is a complex condition with genetic and autoimmune origins.
    • Treatment options range from corticosteroids to topical immunotherapy and immunosuppressants.
    • Addressing the psychological morbidity associated with AA is essential for successful management.
