Autoimmune Disorders

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.

Cells of the Adaptive Immune Response

Cells 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...

Inflammatory Bowel Disease III: Crohn's Disease

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...

T Cell Activation and Clonal Selection

T 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.
Naive T cells that have not yet encountered an antigen express two primary CD...

T Cell Types and Functions

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...

Chronic Inflammation: Introduction

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...

Summary

Expanded CD8+ T cells in multiple sclerosis (MS) recognize Epstein-Barr virus (EBV) antigens. This suggests a link between antiviral immunity and central nervous system (CNS) pathology in MS.

Area of Science:

Neuroimmunology
Virology
Immunology

Background:

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system (CNS).
The role of Epstein-Barr virus (EBV) in MS pathogenesis is under investigation.
CD8+ T cells are key immune cells implicated in CNS inflammation.

Purpose of the Study:

To investigate the specificity of CD8+ T cell clones expanded in the CNS of MS patients.
To determine if these T cells recognize EBV antigens.
To explore the potential link between EBV infection and MS pathology.

Main Methods:

Isolation and characterization of CD8+ T cell clones from cerebrospinal fluid (CSF) of MS patients.
Antigen recognition assays using EBV-derived peptides.

Analysis of T cell activation markers and cytokine production.

Main Results:

Expanded CNS CD8+ T cell clones from MS patients demonstrated recognition of specific EBV antigens.
A significant proportion of these T cell clones were reactive to EBV-derived epitopes.
This recognition suggests a role for EBV-specific T cell responses in CNS inflammation in MS.

Conclusions:

CNS-infiltrating CD8+ T cells in MS patients can recognize EBV antigens.
This finding provides a direct link between antiviral immunity against EBV and the ongoing pathology in the CNS of MS patients.
Targeting EBV-specific immune responses may offer a therapeutic strategy for MS.
