The aim of the present investigation was to establish if serum IgG antibodies (pSS IgG) were able to interact with cholinoreceptors in rat submandibular gland-dependent stimulation of cyclooxygenase 2 (COX-2) mRNA expression and PGE\n                    <jats:sub>2<\/jats:sub>\n                    production. Our findings indicated that pSS IgG-stimulating M\n                    <jats:sub>3<\/jats:sub>\n                    , M\n                    <jats:sub>4<\/jats:sub>\n                    , and M\n                    <jats:sub>1<\/jats:sub>\n                    cholinoreceptors exerted an increase in COX-2 mRNA without affecting COX-1 mRNA expression and increased PGE\n                    <jats:sub>2<\/jats:sub>\n                    production. Inhibitors of phospholipase A\n                    <jats:sub>2<\/jats:sub>\n                    , COX- s, L-type calcium channel currents, and Ca\n                    <jats:sup>2+<\/jats:sup>\n                    -ATPase from sarcoplasmic reticulum prevented the pSS IgG effect on PGE\n                    <jats:sub>2<\/jats:sub>\n                    production. An ionophore of calcium mimicked pSS IgG action, suggesting a crucial role of calcium homeostasis in the cholinoreceptor-stimulated increase in PGE\n                    <jats:sub>2<\/jats:sub>\n                    production.
