Mucosal immunity and primary biliary cirrhosis: Presence of antimitochondrial antibodies in urine
Atsushi Tanaka, Gregory Nalbandian, Patrick S.C. Leung, Gordon D. Benson, Santiago Munoz, Jorge A. Findor, Andrea D. Branch, Ross L. Coppel, Aftab A. Ansari, M. Eric Gershwin – 30 December 2003 – We have shown that IgA‐class antimitochondrial autoantibodies (AMA) can be detected in the bile and saliva of patients with PBC, suggesting that AMA are secreted into the luminal fluid across bile ducts and salivary glands. These data prompted us to determine whether AMA of the IgA isotype may be transported across other epithelial mucosa.
