Summary
Dysregulated Fc receptor (FcR) expression disrupts immune checkpoints, leading to autoimmune diseases. Understanding FcR balance is key to developing new therapies for these conditions.
Area of Science:
- Immunology
- Autoimmunity
- Molecular Biology
Background:
- Autoimmune disorders involve immune system attacks on the body's own tissues.
- Immune responses are regulated by checkpoints to prevent self-tissue destruction.
- Fc receptors (FcR) on immune cells act as critical checkpoints.
Purpose of the Study:
- To review evidence linking aberrant Fc receptor expression to autoimmune diseases.
- To explore the potential of FcR modulation for novel therapeutic strategies.
Main Methods:
- Review of data from murine model systems.
- Analysis of Fc receptor (FcR) expression in autoimmune conditions.
Main Results:
- Coexpression of activating and inhibitory Fc receptors (FcR) establishes an immune activation threshold.
- Disturbed FcR expression is observed in many human autoimmune diseases.
- Aberrant FcR expression in murine models correlates with uncontrolled immune responses and autoimmune initiation.
Conclusions:
- Fc receptor (FcR) dysregulation is a significant factor in autoimmune disease pathogenesis.
- Targeting Fc receptor pathways offers potential for developing new autoimmune disease treatments.

01:29Autoimmune 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.

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.

01:20Myasthenia Gravis: Overview and Treatment
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which leads...

01:22Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
01:24Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF
Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab (Humira),...
01:31Immunoglobulin-like Cell Adhesion Molecules
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...
