Insights

Serum levels of circulating intercellular adhesion molecule-1 (cICAM-1) were elevated in patients with localized scleroderma. Higher cICAM-1 levels correlated with disease severity and immune markers, suggesting immune activation in localized scleroderma.

Area of Science:

  • Immunology
  • Dermatology
  • Rheumatology

Background:

  • Intercellular adhesion molecule-1 (ICAM-1) plays a role in immune responses.
  • Circulating ICAM-1 (cICAM-1) may indicate immune activation.
  • Localized scleroderma exhibits immunologic abnormalities.

Purpose of the Study:

  • To determine if serum cICAM-1 levels are elevated in localized scleroderma patients.
  • To investigate correlations between cICAM-1 levels and clinical/serologic features of localized scleroderma.

Main Methods:

  • Enzyme-linked immunosorbent assay (ELISA) was used to measure serum cICAM-1.
  • Study included 48 patients with localized scleroderma, 20 with systemic sclerosis, and 20 healthy controls.

Main Results:

  • Serum cICAM-1 levels were significantly higher in localized scleroderma patients compared to controls.
  • Elevated cICAM-1 correlated with lesion count, affected areas, antihistone antibody IgM, and soluble interleukin 2 receptor.

Conclusions:

  • Immune activation appears to be a contributing factor in localized scleroderma.
  • cICAM-1 may serve as a biomarker for immune activity in localized scleroderma.

Overview of Cell-Matrix Interactions

The extracellular matrix or ECM holds cells together to form a tissue and allows the cells within the tissue to communicate. ECM comprises proteins such as fibronectin, collagen, laminin, etc. The most abundant protein in this space is collagen. Collagen fibers are interwoven with carbohydrate-containing protein molecules called proteoglycans. ECM allows cell migration and provides a structural scaffold at cell adhesion that anchors the cell when the extracellular matrix proteins interact with...
Intracellular Signaling Affects Focal Adhesions01:17

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.

Cell Adhesion Molecules - Types and Functions

Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).
CAM Families

Immunoglobulin-like Cell Adhesion Molecules

Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
