Insights

Oestrogens significantly impact skin physiology by affecting cells like keratinocytes and melanocytes, and modulating skin appendages. They influence skin aging, pigmentation, and cancer through distinct cellular receptors and signaling pathways.

Area of Science:

  • Dermatology and endocrinology, focusing on skin physiology and hormone action.

Background:

  • Oestrogens play a crucial role in various skin functions.
  • They influence epidermal keratinocytes, dermal fibroblasts, melanocytes, hair follicles, sebaceous glands, and apocrine glands.
  • Oestrogens are implicated in skin aging, pigmentation, hair growth, sebum production, and skin cancer.

Purpose of the Study:

  • To highlight the multifaceted effects of oestrogens on diverse skin components.
  • To review recent advancements in understanding oestrogen receptor expression and signaling pathways in the skin.

Main Methods:

  • Review of existing literature on oestrogen's effects on skin cells and appendages.
  • Analysis of studies detailing oestrogen receptor (ERalpha and ERbeta) expression.
  • Examination of research on cell surface receptor-mediated signaling pathways.

Main Results:

  • Oestrogens modulate key skin cell types and appendages.
  • Actions are mediated via intracellular receptors (ERalpha, ERbeta) and cell surface receptors.
  • Specific signaling pathways activated by oestrogens in skin cells have been identified.

Conclusions:

  • Oestrogens exert significant regulatory effects on skin structure and function.
  • Understanding oestrogen receptor subtypes and signaling pathways is key to comprehending oestrogen's role in skin health and disease.
  • Further research into these mechanisms can inform therapeutic strategies for skin conditions.

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,...
Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

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 D3(cholecalciferol).

Introduction to the Integumentary System

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...

Accessory Structures of the Skin: Sebaceous Glands

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...
Testosterone: Functions and Regulation01:26

Testosterone: Functions and Regulation

The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
Major Hormones and Their Functions01:27

Major Hormones and Their Functions

Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.
