ANXA11 and immunoglobulin G4-related sclerosing disease: Antibodies to laminin 511-E8 in patients with AIP and antibodies to annexin A11 in patients with AIP/IAC are reported, and therefore, the response frequencies of anti-laminin 511-E8 and anti-annexin A11 antibodies in IgG4-RD patients with and without pancreatic or biliary involvement were compared [15,25,66]; No significant differences were observed [66].
