Accessory Structures of the Skin: Hair and Hair Follicles01:16

Accessory Structures of the Skin: Hair and Hair Follicles

5.9K
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...

The Skin Microbiota01:27

The Skin Microbiota

93
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...

Papillary Dermis01:11

Papillary Dermis

7.0K
Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

Tissue Membranes01:27

Tissue Membranes

13.2K
A tissue membrane is a thin layer of cells that covers the outside of the body, the organs, internal passageways that lead to the exterior of the body, and the lining of the moveable joint cavities. There are two basic types of tissue membranes— connective tissue and epithelial membranes.
Connective Tissue Membranes
The connective tissue membrane is formed solely from connective tissue. These membranes encapsulate organs, such as the kidneys, and line our movable joints. A synovial...

Introduction to the Integumentary System

16.6K
The integumentary system is the organ system that comprises the skin and its associated structures. It is the largest system in the human body and plays a crucial role in protecting and maintaining homeostasis. The integumentary system serves several functions including protection, regulation, sensation, and secretion.
The skin, which is the primary organ of the integumentary system, consists of three main layers: the epidermis, dermis, and hypodermis (subcutaneous tissue). The epidermis is the...

Alveoli and Alveolar Ducts01:26

Alveoli and Alveolar Ducts

7.3K
The respiratory zone of the human body, which stands in contrast to the conducting zone, comprises the structures that actively participate in the exchange of gases. The initiation of this zone is marked by the terminal bronchioles converging into respiratory bronchioles, the tiniest bronchiole classification. The respiratory bronchioles give way to the alveolar ducts that opens into a congregation of alveoli. Actively involved in gas exchange, alveoli resemble tiny sacs similar to clusters of...

Summary

Hypoxia-inducible factors are crucial for skin barrier formation. These factors promote epidermal differentiation and filaggrin expression, enhancing skin barrier function in the epidermis.

Area of Science:

  • Dermatology
  • Molecular Biology
  • Cell Biology

Background:

  • The epidermis, the outermost skin layer, is a hypoxic tissue.
  • The precise roles of hypoxia in epidermal differentiation and skin barrier integrity remain unclear.

Purpose of the Study:

  • To investigate the function of hypoxia-inducible factors (HIFs) in epidermal differentiation.
  • To elucidate the mechanisms by which hypoxia influences skin barrier formation.

Main Methods:

  • Analysis of gene expression related to hypoxia and epidermal differentiation.
  • Studies on the role of HIFs in promoting filaggrin expression.

Main Results:

  • Hypoxia-inducible factors are integral to epidermal differentiation.
  • HIFs significantly promote the expression of filaggrin, a key skin barrier protein.
  • These findings highlight the importance of hypoxia in maintaining skin barrier function.

Conclusions:

  • Hypoxia-inducible factors play a central role in epidermal development and skin barrier establishment.
  • Targeting HIFs could offer new therapeutic strategies for skin barrier disorders.
