Insights

MicroRNAs (miRNAs) regulate skin barrier function by influencing keratinocyte differentiation and proliferation. Understanding these microRNAs offers potential for treating skin diseases like eczema and psoriasis.

Area of Science:

  • Molecular Biology
  • Dermatology
  • Gene Regulation

Background:

  • MicroRNAs (miRNAs) are key regulators of cellular activities, including cell growth, differentiation, and apoptosis.
  • Epidermal barrier integrity is crucial for skin health and is influenced by genetic and environmental factors.
  • miRNAs play a significant role in maintaining skin barrier function in keratinocytes.

Purpose of the Study:

  • To review the association of miRNAs with epidermal barrier integrity.
  • To explore the role of miRNAs in keratinocyte differentiation, proliferation, cell-cell adhesion, and skin lipids.
  • To discuss the potential of miRNA-based technologies for treating skin diseases.

Main Methods:

  • Literature review of studies investigating miRNAs in skin barrier function.
  • Analysis of the impact of miRNAs on epidermal cell differentiation, proliferation, and lipid metabolism.
  • Examination of the link between miRNAs and skin conditions such as atopic dermatitis, ichthyoses, and psoriasis.

Main Results:

  • miRNAs are significantly associated with keratinocyte differentiation and proliferation.
  • The role of miRNAs in cell-cell adhesion and skin lipids requires further investigation.
  • miRNAs are implicated in the pathogenesis of several inflammatory skin diseases.

Conclusions:

  • miRNAs are critical regulators of epidermal barrier integrity.
  • miRNA-based therapies hold promise for managing skin diseases.
  • Further research is needed to fully elucidate the complex interactions between miRNAs and the structural components of the skin barrier.

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...

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...

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...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

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...
