Ovarian antibodies

Description: 
Autoantibodies to ovarian tissue are mainly restricted to the theca cells. These are steroid producing cells and it has been demonstrated that the molecular target is the enzyme 17/alpha-hydroxylase (17/alpha-OH). Antibodies to 17/alpha-OH are found in patients with ovarian failure with autoimmune Addison’s disease (100%) and to a lesser extent in both autoimmune polyendocrine syndromes types 1 and 2 without ovarian failure. The incidence is reportedly very low in other autoimmune disorders such type1 diabetes and thyroid disease. The assay is an indirect immunofluorescence type using monkey ovary as a substrate.
