t-helper type 1 and 2 cytokine levels in patients with benign and malignant salivary gland tumors

چکیده
background: salivary gland tumors are among malignancies that have high recurrence rate. immune responses in salivary gland tumors have not been well elucidated. t helper type 1 (th1) and th2 cytokines have been reported to play a role in the outcome of head and neck cancers. objective: to evaluate the serum levels of interferon gamma (ifn- γ), as the hallmark of th1 cytokines, and interleukin-4 (il-4), as the hallmark of th2 cytokines, in patients with benign and malignant salivary gland tumors in comparison with healthy controls. methods: fifty patients with benign and 14 patients with malignant salivary gland tumors, as well as 23 healthy individuals were recruited. serum levels of ifn-γ and il-4 were measured using elisa method. nonparametric tests were used for data analysis. results: serum levels of ifn-γ and il-4 were found not to be significantly different in patients compared to the control group (0.68 ± 0.29 vs. 1.03 ± 0.57 pg/ml, p=0.58 for ifn-γ, 4.57 ± 1.57 vs. 4.41 ± 1.31 pg/ml, p=0.28 for il-4). ifn-γ and il-4 serum levels were also not significantly different between patients with benign and malignant salivary gland tumors (p=0.54 and p=0.86, respectively). conclusion: the systemic levels of il-4 and ifn-γ seem not to be associated with salivary gland tumor in our study. investigation of other cytokines produced by th1 and th2 cells are warranted.

متن کاملSerum Levels of Cyfra 21 in Patients with Benign and Malignant Salivary Gland Tumors
Introduction: Cyfra 21 is a serum-soluble fragment of cytokeratin19. Increased Cyfra 21 serum levels and their benefit as a tumor marker have been shown in some malignancies. This study aimed to evaluate the serum levels of Cyfra 21 in patients with benign and malignant salivary gland tumors. Materials and Methods: In this cross-sectional study, the serum level of Cyfra 21 in 44 patients with m...
متن کاملMTA1 Expression in Benign and Malignant Salivary gland Tumors
Introduction: Salivary gland tumors (SGTs) are important parts of human neoplasms. The most common SGT is pleomorphic adenoma and the most common malignant SGTs are mucoepidermoid carcinoma and adenoid cystic carcinoma (ACC). Metastasis-associated genes 1 (MTA1), a member of the nucleosome remodeling and histone deacetylation complex, is one newly discovered gene which recruits histone deacetyl...
متن کاملNeoangiogenesis in Benign and Malignant Salivary Gland Tumors
Introduction: There are few studies investigating the role of neoangiogenesis in biological behavior of salivary gland tumors. CD105 expression has demonstrated greater accuracy for detecting new vessel formation compared with other pan-endothelial molecules. This study aimed to assess and compare intratumoral Micro-Vessel Density (MVD) through using immunohistochemichal expression of CD105 bio...
متن کاملGSK3β and CREB3 Gene Expression Profiling in Benign and Malignant Salivary Gland Tumors
Background: Salivary gland tumors (SGT) are rare lesions with uncertain histopathology. One of the major signaling pathways that participate in the development of several tumors is protein kinase A. In this pathway, glycogen synthase kinase β (GSK3β) and cAMP responsive element binding protein (CREB3) are two genes which are supposed to be down regulated in most human tumors. The expression lev...
