Receptors, antibodies, and disease

Area of Science:

• Immunology
• Endocrinology
• Neurology

Background:

• Autoimmune diseases involve abnormal antibody production targeting receptors.
• Mechanisms include blocking receptor binding or accelerating receptor degradation.
• Autoantibodies can mimic hormone actions, causing excess symptoms.

Purpose of the Study:

• To review known anti-receptor autoimmune diseases.
• To discuss emerging evidence for anti-receptor antibodies in other conditions.
• To detail available assays for detecting these autoantibodies.

Main Methods:

• Review of literature on autoimmune diseases and autoantibodies.
• Description of assays for detecting anti-receptor antibodies in serum.
• Discussion of specific diseases with potential anti-receptor etiology.

Main Results:

• Established anti-receptor autoimmune diseases include myasthenia gravis and Graves' disease.
• Autoantibodies exhibit functional heterogeneity, causing insufficiency or excess.
• Assays for autoantibodies are available for clinical and research use.

Conclusions:

• Anti-receptor antibodies are central to specific endocrine and neurological autoimmune diseases.
• Further research is needed for conditions with fragmentary evidence of anti-receptor etiology.
• Assays are crucial for diagnosis and understanding of these autoimmune disorders.
