Summary
T helper 17 (Th17) cells and Interleukin-17 (IL-17) are elevated in lupus erythematosus (LE) patients, indicating their role in the pathogenesis of systemic lupus erythematosus (SLE), discoid lupus (DLE), and subacute cutaneous lupus (SCLE).
Area of Science:
- Immunology
- Autoimmune Diseases
- Dermatology
Background:
- Lupus erythematosus (LE) is a multi-system autoimmune disease.
- Immunological factors, particularly T lymphocyte dysfunction, are key in LE pathogenesis.
- T helper 17 (Th17) cells are implicated in various autoimmune conditions.
Purpose of the Study:
- To investigate the circulating Th17 cell population in patients with different forms of lupus erythematosus.
- To assess the levels of IL-17A, IL-17F, and IL-23 in lupus patients.
Main Methods:
- Recruited 15 LE patients, categorized into systemic lupus erythematosus (SLE), discoid lupus (DLE), and subacute cutaneous lupus (SCLE).
- Measured serum IL-17A, IL-17F, and IL-23 levels.
- Quantified circulating Th17 cells and CD3+IL-17+ cells using flow cytometry.
Main Results:
- Elevated serum IL-17A and IL-17F levels were observed in SLE, DLE, and SCLE patients compared to healthy controls.
- Increased numbers of Th17 cells were found in SLE and DLE patients.
- Higher counts of CD3+IL-17+ cells were detected in SLE, DLE, and SCLE patients.
Conclusions:
- Th17 lymphocytes play a significant role in the pathogenesis of lupus erythematosus.
- Interleukin-17 (IL-17) is implicated in the immunopathogenesis of SLE, DLE, and SCLE.

01:24T 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.

01:23Cells of the Adaptive Immune Response
The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...
01:22T Cell Activation and Clonal Selection
T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
