Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...
Surface Membrane Barriers01:18

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
Sensory Functions of the Skin01:16

Sensory Functions of the Skin

The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...
Cells of the Epidermis01:24

Cells of the Epidermis

The epidermis is made of four or five layers of epithelial cells, depending on its location in the body. From deep to superficial, these layers are the stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
Clinical Applications of Epidermal Stem Cells01:19

Clinical Applications of Epidermal Stem Cells

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 EpiSCs...
Layers of the Epidermis01:21

Layers of the Epidermis

The epidermis, the outermost layer of the skin, is composed of several distinct layers. From deep to superficial, the layers of the epidermis are as follows:
Stratum Basale
Stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis. It is composed of a single layer of actively dividing cells called basal cells or basal keratinocytes. These cells constantly undergo cell division to replenish the upper layers of the epidermis. Additionally, melanocytes, which...

Area of Science:

  • Genetics
  • Dermatology
  • Immunology

Background:

  • Filaggrin gene variants are known risk factors for atopic eczema (AE).
  • Emerging research indicates that other genes within the epidermal differentiation complex (EDC) may also be associated with AE.
  • Understanding the genetic underpinnings of AE is crucial for developing targeted therapies.

Purpose of the Study:

  • To investigate the association between variants in the small proline-rich protein 3 (SPRR3) gene and atopic eczema (AE).
  • To explore the role of the epidermal differentiation complex (EDC) in AE pathogenesis.
  • To identify novel genetic risk factors for atopic eczema.

Main Methods:

  • Genetic association study analyzing SPRR3 variants in patients with AE.
  • Analysis of the epidermal differentiation complex (EDC) gene family.
  • Bioinformatic analysis to predict the functional impact of identified SPRR3 variants.

Main Results:

  • Marenholz and colleagues identified a specific SPRR3 variant that confers susceptibility to atopic eczema (AE).
  • This finding supports the hypothesis that additional epidermal differentiation complex (EDC) genes contribute to AE risk.
  • The study highlights SPRR3 as a potential key player in AE development.

Conclusions:

  • A specific SPRR3 variant is associated with an increased risk of atopic eczema (AE).
  • This research underscores the importance of the epidermal differentiation complex (EDC) in AE pathogenesis.
