Sjögren’s Syndrome (SS) is a systemic autoimmune disease characterized by focal mononuclear cell infiltration into target organs such as salivary and lacrimal glands, leading to sicca symptoms. SS is characterized by the production of numerous circulating autoantibodies. The anti-muscarinic autoantibodies against the type 3 receptor (anti-M3R autoantibodies) in primary SS patients’ sera has recently been studied as its possible involvement in the pathogenesis of SS and a capable diagnostic marker, since M3R plays critical roles in exocrine secretion and smooth muscle contraction. Anti-M3R autoantibodies in the sera of SS patients were detectable with high sensitivity and specificity and had broad inhibitory effects on the exocrine secretion and the smooth muscle contraction mediated by parasympathetic neurons. In Salivary Gland Epithelial Cells (SGECs), the inhibitory.. View More»
