Cerebrospinal-fluid lymphocyte populations and immune complexes in active multiple sclerosis
Lancet (London, England)
|August 2, 1980
Summary
In multiple sclerosis (MS) patients, a specific immune cell type in cerebrospinal fluid (CSF) decreased during flare-ups but normalized during remission. Immune complexes were also detected in the CSF of many MS patients experiencing exacerbations.
Area of Science:
- Neuroimmunology
- Immunology
- Cellular Biology
Background:
- Multiple Sclerosis (MS) is a chronic inflammatory disease of the central nervous system.
- Immune cell populations and immune complex presence in cerebrospinal fluid (CSF) are key indicators of disease activity.
Observation:
- A specific subpopulation of mononuclear cells, identified by the Fc portion of IgG receptor, was significantly reduced in the CSF of MS patients during disease exacerbation.
- Immune complexes were detected in the CSF of approximately 50% of MS patients experiencing exacerbations.
Findings:
- The reduction in Fc-receptor bearing mononuclear cells in CSF was transient, with levels returning towards normal during remission.
- Immune complexes were notably absent in the CSF of MS patients in stable, non-exacerbating phases of the disease.
Implications:
- These findings suggest a dynamic role for specific immune cell subsets and immune complexes in the pathogenesis of MS relapses.
- Monitoring these CSF biomarkers may offer insights into disease activity and inform potential therapeutic strategies for multiple sclerosis.

01:23Introduction to Lymphatic and Immune System
Immunity is a crucial biological concept about our body's inherent capacity to prevent infections and diseases. A complex network of cells and tissues collectively known as the immune system facilitates this natural defense mechanism. The immune system plays an integral role in maintaining our health and well-being, shielding us from potential health threats.
The immune responses can be categorized into two types: innate and adaptive. Innate immunity comprises nonspecific defenses we are born...

01:28Functions of the Lymphatic and Immune System
The lymphatic system plays a crucial role in bolstering our immune system. It consists of a network of lymphoid organs, lymph, and lymphatic vessels that provide structural and functional support in safeguarding the body against pathogens such as viruses and bacteria.
The primary lymphoid organs, including the bone marrow and the thymus, serve as the maturation sites for lymphocytes. Secondary lymphoid organs, like the mucosa-associated lymphoid tissue, activate these lymphocytes and serve as...

01:18Lymphoid Cells and Tissues
Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

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.

01:24B Cell Activation and Differentiation
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...

01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
