PG - 1029-33 AB - OBJECTIVE: To investigate the expression of human beta-defensin-2 (HBD-2) in laryngeal squamous cell carcinoma (LSCC), and reveal the immune significance of HBD-2 in LSCC. METHODS: The expression of HBD-2 and the infiltration of CD1a(+) dendritic cells were verified by immunohistochemistry strept actividin-biotin complex (SABC) method in thirty-four cases of LSCC's paraffin sections, and the expression of HBD-2 mRNA was detected in eighteen cases of postoperative tumor specimens and five cases of normal paracarcinoma tissue using cDNA probe by in situ hybridization. Based on the type and characteristic of datas, SPSS13.0 program package was used for statistical calculation. RESULTS: (1) The difference of expression of HBD-2 was significant among the grades of malignant cell differentiation (F = 6.809, P < 0.05), the expression of HBD-2 in well differentiated group was significantly increased compared with moderately and poorly differentiated group (P < 0.05), there wasn't significant difference with the clinical type, T status and lymphatic metastasis in the expression of HBD-2. (2) The difference of expression of HBD-2 mRNA among different grades of malignant cell differentiation was significant (F = 16.391, P < 0.05), less or no positive signal was observed in poorly differentiated group. (3) The infiltration of CD1a(+) dendritic cells had positive correlation with the expression of HBD-2 (r = 0.343, P < 0.05). CONCLUSIONS: The expression of HBD-2 was related to the grade of malignant cell differentiation in LSCC, which was regulated at the level of transcription and translation. HBD-2 might play a role in anti-tumor immunity by chemo-attractiving and activating of immature dendritic cells.
