APECED Serum
APECED Serum - Human APECED serum from clinically confirmed autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APS-1) donors. Ideal for anti-interferon-omega and organ-specific autoantibody profiling, endocrine biomarker work, and AIRE-driven central tolerance research.
APECED Serum for Monogenic Autoimmunity and Central Tolerance Research
Our APECED Serum is sourced from IRB-consented donors clinically diagnosed with autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED, also known as APS-1). Each sample is processed and frozen within 24 hours of collection to preserve cytokines, autoantibodies, hormones, and other labile analytes. APECED is a monogenic disease caused by biallelic loss-of-function variants in AIRE, which breaks thymic central tolerance and thereby drives multi-organ autoimmunity — making these donors an unusually informative human model for tolerance biology.
Why APECED Serum
- Monogenic cause, autoimmune consequence: biallelic AIRE loss of function impairs thymic presentation of tissue-restricted antigens, allowing autoreactive T cells to escape negative selection and driving organ-specific autoimmunity.
- Neutralising anti-cytokine autoantibodies: high-titre neutralising autoantibodies against interferon-omega and interferon-alpha are near-universal in APECED and are effectively diagnostic. Serum is the standard matrix for detecting and titrating them.
- Anti-IL-17 and anti-IL-22 autoantibodies are associated with chronic mucocutaneous candidiasis, linking a specific humoral autoimmune target to a clinical phenotype.
- Organ-specific autoantibodies track the classic triad and its extensions: 21-hydroxylase autoantibodies in adrenal insufficiency, NALP5 autoantibodies in hypoparathyroidism, and additional targets across thyroid, gonadal, gastric, and hepatic involvement.
- Endocrine analytes: serum supports parallel measurement of calcium, parathyroid hormone, cortisol, ACTH, and thyroid function markers alongside autoantibody testing.
- Rare-disease access: APECED is very rare, and clinically confirmed donor serum is difficult to obtain outside of specialist registries.
