Insights

Human leukocyte antigen (HLA) associations suggest a genetic predisposition to scleroderma and morphea, with specific HLA types linked to distinct disease patterns and immune responses, potentially aiding diagnosis and prognosis.

Area of Science:

  • Immunogenetics
  • Dermatology
  • Autoimmune Diseases

Context:

  • Progressive systemic scleroderma (PSS) and morphea are distinct dermatological disorders with potential autoimmune components.
  • Genetic factors, particularly human leukocyte antigen (HLA) associations, are being investigated for their role in disease susceptibility and manifestation.
  • Previous research suggests a link between HLA types and autoimmune diseases, but specific associations for PSS and morphea require further elucidation.

Purpose:

  • To investigate potential associations between HLA (human leukocyte antigen) phenotypes and the development of progressive systemic scleroderma (PSS) and morphea.
  • To compare HLA, glyoxalase, and properdin factor B phenotypes in patients with PSS and morphea against healthy controls.
  • To explore the relationship between specific HLA "risk" antigens, immune response patterns, and clinical subtypes of these dermatological disorders.

Summary:

  • A study involving 40 PSS patients and 42 morphea patients compared their HLA ABCDR/DQ, glyoxalase, and properdin factor B phenotypes with 193 healthy controls.
  • Relative risk values indicated a weak, HLA-linked genetic predisposition for both PSS and morphea.
  • Distinct HLA antigen profiles were associated with PSS (e.g., A1, B8) and morphea (e.g., A3, B7, DR2), correlating with high and low immune responses, respectively.
  • HLA typing may assist in differential diagnosis and prognosis, with HLA-B8 linked to acute PSS and HLA-B7/DR2 to milder morphea.

Impact:

  • Identifies specific HLA associations that may contribute to the genetic predisposition for scleroderma and morphea.
  • Suggests that different HLA "risk" antigens correlate with distinct immune response patterns (high vs. low) in PSS and morphea.
  • Highlights the potential utility of HLA typing for clinical differential diagnosis and prognosis determination in these dermatological conditions.
  • Provides insights into how environmental factors interacting with HLA phenotype may predispose predominantly women to different clinical patterns of these diseases.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
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...
Autoimmune Disorders01:29

Autoimmune Disorders

Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions01:29

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions

Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
Hypersensitivity Reactions: Immune-Complex Reactions01:19

Hypersensitivity Reactions: Immune-Complex Reactions

Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
