Intravenous immunoglobulin (IVIG) therapy uses pooled antibodies to treat autoimmune diseases. This review explores the molecular mechanisms behind IVIG
Area of Science:
- Immunology
- Pharmacology
- Autoimmune Diseases
Background:
- Intravenous immunoglobulin (IVIG) preparations are pooled IgG antibodies from thousands of donors.
- Initially used for IgG replacement in immunocompromised patients.
- IVIG therapy has expanded to treat various autoimmune and inflammatory conditions, including immune thrombocytopenia.
Purpose of the Study:
- To review recent insights into the molecular and cellular pathways of IVIG-mediated immunosuppression.
- To focus on IVIG's therapeutic role in IgG-dependent autoimmune diseases.
Main Methods:
- Literature review of recent scientific findings.
- Analysis of molecular and cellular pathways involved in IVIG action.
Main Results:
- Despite broad efficacy, the precise mechanisms of IVIG action remain incompletely understood.
- Recent research is elucidating key pathways involved in IVIG-mediated immunosuppression.
Conclusions:
- IVIG is a valuable therapy for numerous autoimmune and inflammatory diseases.
- Further understanding of IVIG's molecular and cellular mechanisms is crucial for optimizing its use, particularly in IgG-dependent autoimmune conditions.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
