[Pathogenesis of systemic lupus erythematosus].

Area of Science:

• Immunology
• Autoimmune Diseases
• Rheumatology

Background:

• Systemic lupus erythematosus (SLE) is an autoimmune disease with complex, incompletely understood origins.
• Genetic predisposition is a known factor, but environmental triggers are crucial for disease onset and flares.
• Pathogenic autoantibodies, particularly those produced by B-cells and plasma cells, are central to SLE pathogenesis.

Purpose of the Study:

• To review the most frequent factors contributing to SLE development.
• To elucidate the key pathogenic mechanisms underlying SLE.
• To provide a comprehensive overview of SLE etiology and pathogenesis.

Main Methods:

• Literature review of factors and mechanisms in SLE development.
• Synthesis of current understanding of genetic and environmental influences.
• Analysis of the role of B-cells, plasma cells, and autoantibodies in SLE pathogenesis.

Main Results:

• Identified genetic predisposition and environmental factors (sunburn, infections, vitamin D deficiency) as primary triggers for SLE.
• Highlighted the critical role of B-cells and plasma cells in producing pathogenic autoantibodies.
• Confirmed that environmental factors can also precipitate disease flares.

Conclusions:

• SLE pathogenesis involves a multifactorial interplay between genetic susceptibility and environmental exposures.
• Targeting B-cell and plasma cell activity, along with autoantibody production, is crucial for managing SLE.
• Further research into specific environmental triggers and their interaction with genetic factors is warranted.
