[Pemphigus]

Area of Science:

• Immunodermatology
• Autoimmune Blistering Diseases

Context:

• Pemphigus is a group of rare autoimmune diseases characterized by blistering of the skin and mucous membranes.
• Understanding the underlying mechanisms of pemphigus is crucial for developing effective treatments.

Purpose:

• To review the current understanding of pemphigus pathogenesis, focusing on the role of intercellular antigens, antibodies, complement, and lymphocytic dysfunction.
• To survey evidence supporting the influence of exogenous factors in pemphigus development.
• To summarize potential etiological factors and mechanisms of blister formation in pemphigus.

Summary:

• The review emphasizes the significance of intercellular antigens and antibodies in pemphigus, alongside the involvement of complement system activation and lymphocytic dysfunction.
• Evidence from existing literature regarding exogenous factors that may trigger pemphigus is examined.
• The authors synthesize current knowledge to propose possibilities for the etiology and the characteristic blister formation in pemphigus.

Impact:

• This review provides a comprehensive overview of pemphigus pathogenesis, aiding researchers and clinicians in understanding the disease.
• It may guide future research directions for identifying novel therapeutic targets and diagnostic markers for pemphigus.
• The synthesized information can contribute to improved patient management and outcomes for individuals with pemphigus.
