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.

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...

Intracellular Signaling Affects Focal Adhesions

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.

Activation of Integrins01:15

Activation of Integrins

Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
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

Animal and protozoan cells do not have cell walls to help maintain shape and provide structural stability. Instead, these eukaryotic cells secrete a sticky mass of carbohydrates and proteins into the spaces between adjacent cells. This network of proteins and molecules is called an extracellular matrix or ECM.
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,...
Chronic Inflammation: Introduction01:12

Chronic Inflammation: Introduction

Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...

Introduction to Fibroblasts

Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...
