Study Notes
Autoantibodies and Diseases
- Autoantibodies against acetylcholine receptors (ACh) are involved in myasthenia gravis
- Autoantibodies against thyroid-stimulating hormone (TSH) are involved in Graves' disease
- Autoantibodies against thyroid peroxidase (anti-TPO) are involved in Hashimoto's thyroiditis
Autoantibodies as Biomarkers
- Autoantibodies against tissue transglutaminase (Anti-TTG) are used as biomarkers for Coeliac disease
Autoantibodies in Rheumatoid Arthritis
- Autoantibodies against citrullinated proteins (ACPA) are involved in Rheumatoid Arthritis
Autoantibodies in Systemic Lupus Erythematosus (SLE)
- Autoantibodies against complement component 1q (Anti-C1q) are involved in SLE, leading to excessive complement activation
Human Leukocyte Antigens (HLA) and Diseases
- HLA-B27 is associated with Ankylosing Spondylitis
- HLA-DQ2 is associated with Coeliac Disease
- HLA-DRB1 is associated with Rheumatoid Arthritis
Graft Rejection
- Hyperacute graft rejection is mediated by IgM antibodies, causing red blood cell (RBC) lysis
- Acute graft rejection is characterized by alloreactive T-cell infiltration
- Chronic graft rejection is characterized by alloreactive T-cells, alloantibodies, and fibrosis
