Production of proinfl ammatory cytokines by peripheral blood mononuclear cells in cocultures with squamous cell carcinoma of the larynx
Journal Title: Otolaryngologia Polska - Year 2009, Vol 63, Issue 7
Abstract
Purpose: Antitumor mechanisms of cellular immune response are connected with the cytokines activity secreted by peripheral blood mononuclear cells (PBMC). The aim of this study was estimation of proinflammatory cytokine (IL-6 and TNF- ) concentration in patients with laryngeal squamous cell carcinoma and analysis of directed influence of neoplasm cells to the function of PBMC and modification of cytokine profile. Materials and methods: For analysis of cytokine secretion, the cultures of isolated peripheral blood mononuclear cells (PBMC) with marginal neoplasm cells and noncancerous adjacent mucosa cells from 55 patients with laryngeal squamous cell carcinoma were established. Production of cytokines in 21h and 72h culture supernatants was detected by Elisa. Results: Authors reported the increase of IL-6 and decrease of TNF- concentration in cultures of isolated peripheral blood mononuclear cells (PBMC) with marginal neoplasm cells and non-cancerous adjacent mucosa cells. Conclusion: The presence of laryngeal squamous carcinoma cells in PBMC culture can modify immunocompetent cells activity and production of proinfl ammatory cytokines.
