Summary
Eph receptor tyrosine kinases and ephrin ligands facilitate cell communication, crucial for skin health. Dysregulation of this pathway impacts skin conditions, suggesting therapeutic potential.
Area of Science:
- Dermatology
- Cell Biology
- Molecular Biology
Background:
- Eph receptor tyrosine kinases (RTKs) and ephrin ligands mediate cell-cell communication.
- This signaling pathway is vital for tissue morphogenesis and homeostasis.
- Eph/ephrin signaling is present in various skin structures, including epidermis and hair follicles.
Purpose of the Study:
- To review the role of Eph receptors and ephrins in epidermal keratinocytes.
- To explore their function in keratinocyte proliferation, migration, differentiation, and apoptosis.
- To examine the involvement of Eph/ephrin signaling in skin diseases.
Main Methods:
- Literature review of studies on Eph/ephrin signaling in skin.
- Analysis of the role of Eph receptors and ephrins in keratinocyte behavior.
- Examination of the association between Eph/ephrin axis alterations and skin disorders.
Main Results:
- Eph/ephrin signaling modulates keratinocyte proliferation, migration, differentiation, and death.
- Activation of Eph receptors by ephrins is critical for intercellular junction maturation during keratinocyte differentiation.
- Altered Eph/ephrin signaling is linked to skin conditions like malignancy, impaired wound healing, and inflammation.
Conclusions:
- The Eph/ephrin cell-cell communication pathway plays a significant role in epidermal homeostasis.
- Dysregulation of this axis is associated with various dermatological disorders.
- Targeting the Eph/ephrin pathway may offer therapeutic strategies for restoring skin integrity.

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
01:12Renewal 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,...
01:19Clinical 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...
03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...
