PG - 220-4 AB - OBJECTIVE: To detect the FcgammaRⅡB content of monocytes and B cells,the concentration of soluble FcgammaRⅡB( s FcgammaRⅡB) and its antibodies in the peripheral blood of patients with lung squamous cell carcinoma( LSCC) before and after chemotherapy. METHODS: The expression and localization of FcgammaR Ⅱ B on monocytes and B cells were detected by immunofluorescence technique; the expression of FcgammaR Ⅱ B mRNA was examined by quantitative real-time PCR; Western blotting was performed to detect the expression of FcgammaRⅡB protein; the serum concentrations of s FcgammaRⅡB,s FcgammaRⅡB-Ig G complex,anti-FcgammaRⅡB autoantibody were determined by ELISA. RESULTS: The expression of FcgammaRⅡB on monocytes and B cells,the total s FcgammaRⅡB and anti-FcgammaRⅡB antibody content in the sera of LSCC patients were lower than those in healthy volunteers. Chemotherapy enhanced the expression of FcgammaRⅡB both on the detected cell surface and in the peripheral blood of patients with LSCC,and increased the serum concentration of anti-FcgammaR Ⅱ B autoantibodies as well. In addition,the concentration of s FcgammaR Ⅱ B-Ig G in the peripheral blood was higher in LSCC patients than that in healthy volunteers,and it decreased after chemotherapy. CONCLUSION: The level of FcgammaRⅡB decreases in LSCC patients,but it rises after chemotherapy.
