Insights

This review compares gene expression in inflammatory fibrotic disorders. While most diseases show unique molecular pathways, adult and pediatric lichen sclerosus, and localized scleroderma share similarities in antigen processing and interferon pathways.

Area of Science:

  • Dermatology and Rheumatology
  • Molecular Biology
  • Genomics

Background:

  • Inflammatory fibrotic disorders share a common endpoint (fibrosis) but present with diverse clinical features and treatments.
  • Understanding distinct molecular pathways is crucial for targeted therapies in conditions like scleroderma and lichen sclerosus.

Purpose of the Study:

  • To investigate and compare the underlying molecular pathways in various inflammatory fibrotic diseases.
  • To determine if shared or unique gene expression profiles exist across conditions such as localized scleroderma, pediatric and adult lichen sclerosus, eosinophilic fasciitis, and systemic sclerosis.

Main Methods:

  • A comprehensive analysis and comparison of numerous gene expression microarray studies.
  • Utilized data from skin and fibroblast samples of patients diagnosed with the specified inflammatory fibrotic disorders.

Main Results:

  • Most inflammatory fibrotic diseases exhibit unique gene expression signatures, reflecting their heterogeneous phenotypes.
  • A significant overlap in gene expression was identified between adult lichen sclerosus, pediatric lichen sclerosus, and localized scleroderma, particularly concerning antigen processing and interferon pathways.

Conclusions:

  • The findings suggest distinct molecular underpinnings for different inflammatory fibrotic diseases, despite clinical similarities.
  • Identifying shared pathways, like those involving antigen processing and interferon signaling, offers potential for novel diagnostic and therapeutic strategies.

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...

T Cell Types and Functions01:24

T Cell Types and Functions

When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Inflammatory Bowel Disease III: Crohn's Disease

Crohn’s disease is a chronic, relapsing form of inflammatory bowel disease characterized by segmental, transmural inflammation that can affect any part of the gastrointestinal tract. Its pathogenesis arises from a combination of genetic susceptibility, environmental exposures, epithelial barrier dysfunction, and immune dysregulation. Together, these factors lead to an exaggerated immune response against components of the gut microbiome.Genetic and Environmental InfluencesMultiple genetic...

Inflammatory Response01:28

Inflammatory Response

An inflammatory response is a localized, nonspecific immune reaction that occurs when a tissue is injured. It is characterized by redness, swelling, heat, and pain, which are commonly called the cardinal signs and symptoms of inflammation. Inflammation can sometimes result in a loss of function.
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...

Inflammatory Response II: Inflammatory Exudate and Tissue Repair01:24

Inflammatory Response II: Inflammatory Exudate and Tissue Repair

The immune system's inflammatory response destroys the invading pathogen, permitting the tissue to heal. The changes during the cellular and vascular stages allow exudate formation at the site of inflammation. The inflammatory exudate released from the wound has high protein content and a specific gravity above 1.020.
The typical wound exudate is odorless, transparent, straw-colored, thin, and watery. Exudate, however, can differ depending on the state of wound healing. Likewise, the...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...
