Abstract:
Fibrosis is a major cause of morbidity and mortality worldwide. Currently, therapeutic options for tissue fibrosis are severely limited, and organ transplantation is the only effective treatment for end-stage fibrotic disease. However, demand for donor organs greatly outstrips supply, and so effective anti-fibrotic treatments are urgently required. In recent years, the integrin family of cell adhesion receptors has gained prominence as key regulators of chronic inflammation and fibrosis. Fibrosis models in multiple organs have demonstrated that integrins have profound effects on the fibrotic process. There is now abundant in vivo data demonstrating critical regulatory roles for integrins expressed on different cell types during tissue fibrogenesis. In this review, we will examine the ways in which integrins regulate these processes and discuss how the manipulation of integrins using function blocking antibodies and small molecule inhibitors may have clinical utility in the treatment of patients with a broad range of fibrotic diseases. This article is part of a Special Issue entitled: Fibrosis: Translation of basic research to human disease.
Insights
Integrins, cell adhesion receptors, are key regulators of fibrosis. Targeting integrins with therapies like antibodies offers potential for treating fibrotic diseases, addressing a critical unmet medical need.
Area of Science:
- Cell Biology
- Immunology
- Pathology
Background:
- Fibrosis is a significant global health issue causing widespread morbidity and mortality.
- Current treatments for tissue fibrosis are limited, with organ transplantation being the only option for end-stage disease.
- The urgent need for effective anti-fibrotic therapies is driven by the gap between donor organ supply and demand.
Purpose of the Study:
- To review the regulatory roles of integrins in fibrotic processes across multiple organs.
- To discuss the potential clinical applications of integrin-targeting therapies for fibrotic diseases.
Main Methods:
- Review of in vivo data and scientific literature on integrin function in fibrosis.
- Examination of the mechanisms by which integrins regulate tissue fibrogenesis.
- Analysis of therapeutic strategies involving integrin manipulation.
Main Results:
- Integrins are critical regulators of chronic inflammation and fibrosis.
- In vivo studies confirm the significant impact of integrins on fibrotic processes in various organs.
- Integrins expressed on different cell types play crucial roles in tissue fibrogenesis.
Conclusions:
- Integrin-based therapies, including function-blocking antibodies and small molecule inhibitors, show promise for treating a wide spectrum of fibrotic diseases.
- Targeting integrins represents a potential therapeutic avenue to combat the significant burden of fibrotic conditions.

Activation of Integrins
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding events provide an effective stimulus.
Integrins
Some ECM proteins assemble into a basement membrane to which the remaining components adhere. Proteoglycans typically form the bulk of the ECM while fibrous proteins, like collagen,...
