The possible role of Epstein-Barr virus (EBV) in the pathogenesis of Sjögren's syndrome (SS) has been suggested. However, the evidence has been circumstantial and it is not known at all whether cellular immune responses to EBV are linked to the mechanism of the disease. Although the oligoclonal expansion of T lymphocytes in salivary glands of SS was indicated by some analyses of the T cell receptors, the corresponding ligands are unknown. The key question may be of whether this disorder involves virus specific immune attacks on the salivary glands being a site for EBV latency. We introduce here our functional study of the salivary gland-infiltrating T lymphocytes in patients with SS for detecting EBV specific memory T cells. The potential association of the state of EBV-specific CTL in the lesion with the reactivation of EBV will be discussed.

UI	MeSH Term	Description	Entries
D004854	Herpesvirus 4, Human	The type species of LYMPHOCRYPTOVIRUS, subfamily GAMMAHERPESVIRINAE, infecting B-cells in humans. It is thought to be the causative agent of INFECTIOUS MONONUCLEOSIS and is strongly associated with oral hairy leukoplakia (LEUKOPLAKIA, HAIRY;), BURKITT LYMPHOMA; and other malignancies.

D012469	Salivary Glands	Glands that secrete SALIVA in the MOUTH. There are three pairs of salivary glands (PAROTID GLAND; SUBLINGUAL GLAND; SUBMANDIBULAR GLAND).	Gland, Salivary,Glands, Salivary,Salivary Gland
D012859	Sjogren's Syndrome	Chronic inflammatory and autoimmune disease in which the salivary and lacrimal glands undergo progressive destruction by lymphocytes and plasma cells resulting in decreased production of saliva and tears. The primary form, often called sicca syndrome, involves both KERATOCONJUNCTIVITIS SICCA and XEROSTOMIA. The secondary form includes, in addition, the presence of a connective tissue disease, usually rheumatoid arthritis.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
