Insights

Periostin, a skin glycoprotein, is abnormally expressed in various skin diseases and contributes to fibrosis and immune responses. Targeting periostin may offer new therapeutic strategies for dermatoses.

Area of Science:

  • Dermatology
  • Immunology
  • Biochemistry

Background:

  • Skin damage from injury, inflammation, and autoimmunity triggers tissue remodeling.
  • Extracellular matrix components are crucial for facilitating tissue remodeling.
  • Periostin, a glycoprotein from dermal fibroblasts, is a key component of the extracellular matrix.

Purpose of the Study:

  • To review current knowledge on periostin's role in skin disease pathogenesis.
  • To investigate periostin as a potential therapeutic target for dermatoses.

Main Methods:

  • Literature review of studies on periostin in skin conditions.
  • Analysis of periostin expression patterns in normal and lesional skin.
  • Examination of periostin's functional roles in fibrosis and immune responses.

Main Results:

  • Periostin is aberrantly expressed in various lesional skin conditions, including atopic dermatitis, scars, scleroderma, melanoma, and cutaneous T cell lymphoma.
  • Periostin promotes dermal fibrosis and modulates immune responses.
  • Aberrant periostin expression is linked to skin damage from allergic and autoimmune reactions.

Conclusions:

  • Periostin plays a significant role in the pathogenesis of numerous dermatoses.
  • Periostin represents a promising therapeutic target for treating various skin diseases.

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...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

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...

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...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
