Abstract:
BACKGROUND: It remains unclear whether proinflammatory factor, such as tumor necrosis factor-α (TNF-α), γ-interferon and anti-inflammatory cytokine, such as interleukin-10 (IL-10), interleukin-4 (IL-4) levels can change after laryngeal transplantation. OBJECTIVE: To explore the expression of TNF-α and IL-10 in different expressive tissue layers and its relationship during the acute rejection episodes, and to evaluate the role of TNF-α and IL-10 levels in serum for prediction of early acute rejection after laryngeal transplantation. METHODS: Laryngeal heterotopic transplantations were performed in Wistar and Sprague-Dawley rats. According to different dosages of immunodepressant, all recipients were divided into three groups: Group 0 mg, Group 5 mg, and Group 10 mg. Untreated Sprague-Dawley rats served as normal control group. RESULTS AND CONCLUSION: Changes in serum TNF-α and IL-10 levels at postoperation days 3, 7 and 11 were positively correlated with these expressions in the epithelium mucosa and submucosa at various time points after transplantation. These indicate that the high-antigenicity of graft mainly concentrates on the layers of mucosa and submucosa. TNF-α and IL-10 concentrations can serve as indexes for predicting acute rejection after laryngeal transplantation.
