소아청소년 틱장애 환자의 B림프구에서 D8/17의 발현

초록

Objectives：It has been reported that higher percentage of B cells react with monoclonal D8/17 antibody in patients with rheumatic fever, childhood onset obsessive-compulsive disorder, Tourette’s disorder, or prepubertal anorexia nervosa. The purpose of this study is to replicate the previous studies in a Korean young population with tic disorder and to identify any relationship between D8/17 and clinical symptoms. Methods：The binding of D8/17 to B cells was determined in patients with tic disorder (N=21) and healthy controls (N=9) by Fluorescence-Activated Cell Sorter analysis. Results：In the sample examined by this study, the average percentage of B cells expressing D8/17 in tic disorder was 2.05%;healthy controls was 3.15%. No statistically significant differences were found in the mean percentages of D8/17 between the two groups. Conclusion：The expression of D8/17 in B cells was very low in this study. No subjects with tic disorder or healthy controls was above 12% in D8/17 positive proportion. Further studies, including higher number of patients and control group members,should be performed.
