New horizons for human pathogenic autoantibodies.

Area of Science:

• Immunology
• Pathology
• Autoimmunity

Background:

• Autoimmune diseases arise from pathogenic autoantibodies targeting self-antigens.
• Recent advances have identified numerous autoantibodies implicated in various autoimmune conditions.
• These autoantibodies disrupt normal physiological functions or lead to cell destruction.

Purpose of the Study:

• To review recent findings on pathogenic autoantibodies across different autoimmune diseases.
• To highlight the diversity of autoantigen targets, including receptors, channels, and cytokines.
• To discuss the clinical manifestations, target protein characteristics, and detection methods for these autoantibodies.

Main Methods:

• Literature review of recent studies on pathogenic autoantibodies.
• Case examples illustrating autoimmune diseases caused by autoantibodies.
• Discussion of diagnostic techniques for autoantibody detection.

Main Results:

• Identification of pathogenic autoantibodies against receptors, channels, cell surface proteins, glomerular proteins, and cytokines.
• Examples provided for neurological, kidney, pulmonary, and acquired immunodeficiency diseases.
• Clinical features and target protein diversity are presented.

Conclusions:

• Pathogenic autoantibodies represent a significant cause of autoimmune disease.
• Understanding autoantibody targets is crucial for disease characterization.
• Further research may lead to novel diagnostic and therapeutic strategies.
