Summary
The bioactive peptide AESIS-1, known for treating rheumatoid arthritis (RA), significantly accelerates wound healing in diabetic mice by enhancing fibroblast migration and CXC chemokine receptor 2 (CXCR2) expression.
Area of Science:
- Biomedical Engineering
- Dermatology
- Immunology
Background:
- Delayed wound healing is common in autoimmune disorders like rheumatoid arthritis (RA).
- Bioactive peptides are being developed as novel skin wound repair materials.
- AESIS-1, a known anti-RA agent, was investigated for wound healing potential.
Purpose of the Study:
- To evaluate AESIS-1 as a therapeutic wound-healing agent.
- To assess its efficacy in a diabetic mouse model of chronic wound repair.
Main Methods:
- A full-thickness excision wound model was used in diabetic mice.
- In vitro studies assessed human dermal fibroblast (HDF) migration and proliferation.
- Mechanisms involving chemokine receptor (CXCR2) and MAPK signaling pathways were investigated.
Main Results:
- AESIS-1 treatment significantly accelerated wound repair in mice compared to controls.
- AESIS-1 enhanced HDF migration without affecting proliferation.
- Upregulation of CXCR2 and activation of ERK and p38 MAPK signaling pathways were observed.
Conclusions:
- AESIS-1 peptide demonstrates strong wound-healing properties.
- It promotes fibroblast migration and CXCR2 expression via MAPK signaling.
- AESIS-1 shows potential as a therapeutic agent for chronic wound repair.

01:19Cell Migration
4.8K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.2K
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.

01:13Cell-matrix's Response to Mechanical Forces
2.6K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.

01:19Clinical Applications of Epidermal Stem Cells
2.7K
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...

01:17Intracellular Signaling Affects Focal Adhesions
2.7K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.
