[Antireceptor and antichannel autoantibodies]

Area of Science:

• Immunology
• Neurology
• Endocrinology

Context:

• Autoimmune diseases involve autoantibodies targeting critical cellular components.
• Membrane receptors and ion channels are key targets in various autoimmune pathologies.
• The role of specific autoantibodies in disease pathogenesis varies and requires further elucidation.

Purpose:

• To review autoantibodies against membrane receptors and ion channels.
• To discuss target antigens, associated pathologies, pathogenesis, and detection methods.
• To explore the diagnostic and therapeutic implications of these autoantibodies.

Summary:

• This review categorizes autoantibodies targeting membrane receptors (enzymatic, G protein-coupled, GPI-anchored) and intracellular receptors (estrogen, androgen, lamin, kinesin).
• It details their association with autoimmune diseases, pathogenesis, and diagnostic detection methods.
• Commonly detected autoantibodies include anti-acetylcholine receptor and voltage-gated channel antibodies, while others are rare.

Impact:

• Autoantibodies serve as diagnostic markers and predict disease activity.
• Their presence supports immunotherapy interventions in autoimmune conditions.
• This review highlights the diagnostic utility and therapeutic relevance of autoantibodies against receptors and channels.
