IL-14 alpha, the nexus for primary Sjögren's disease in mice and humans

To evaluate the role of interleukin 14 alpha (IL-14a) in Sjögren's syndrome (SS), we evaluated the expression of IL-14a in the peripheral blood lymphocytes (PBL) of patients with primary and secondary SS and normal controls by quantitative RT-PCR. In addition, transgenic IL-14a mice were analyz...

520 |a To evaluate the role of interleukin 14 alpha (IL-14a) in Sjögren's syndrome (SS), we evaluated the expression of IL-14a in the peripheral blood lymphocytes (PBL) of patients with primary and secondary SS and normal controls by quantitative RT-PCR. In addition, transgenic IL-14a mice were analyzed from 6 weeks of age to death for both histological and immunological features of Sjögren's disease. Patients with both primary and secondary Sjögren's syndrome expressed IL-14a at statistically higher levels in their peripheral blood compared to normal controls matched for age, sex and ethnic group. Transgenic mice in which IL-14a expression was increased constitutively were previously demonstrated to develop hypergammaglobulinemia, autoantibodies, infiltration of the parotid glands with lymphocytes, mild immune-complex mediated renal disease and large B cell lymphoma. In this paper we expand these observations to demonstrate that these mice develop all the clinical and immunological features of primary Sjögren's disease in the same relative time frame as patients with primary Sjögren's disease: stage 1-early hypergammaglobulinemia and autoantibody production, stage 2-decreased salivary gland function with early lymphocytic infiltration of the submandibular glands only, but antibody deposition in the submandibular and parotid glands, stage 3-lymphocytic infiltration of the submandibular, parotid and lacrimal glands with B and T lymphocytes and plasma cells along with interstitial lung disease and mild renal disease, and stage 4-large B cell lymphoma. Thus IL-14a is important in the pathophysiology of Sjögren's disease. The IL-14a transgenic mouse is a novel animal model that can be utilized to understand the pathophysiology of Sjögren's disease
