Abstract:
OBJECTIVE: Recently, molecular genetic methods have been progressed, this study was to investigate the relationship between schizophrenia and immunologic aspects by analyzing polymorphism of IL-10 gene, which is involved in interaction of immunologic system and CNS. METHOD: 141 schizophrenic patients diagnosed by DSM-IV were included and data of 146 normal controls obtained from the Catholic Hemopoietic Stem Cell Information Bank of Korea were used in this study. DNA was extracted from whole blood, thereafter amplified by polymerase chain reaction, and digested by Mae III After that procedure, we obtained and assessed RFLP of two alleles, IL-10T and IL-10C. All data were analyzed by x2 test with two-tailed Fisher's exact test. RESULTS: 1) There were no significant differences genotype frequencies of IL-10*T/T, IL-10*T/C, and IL-10*C/C in between schizophrenic patients group and control group. 2) There were no significant differences gene frequencies of IL-10*T and IL-10*C in between schizophrenic patients group and control group. CONCLUSION: We did not verified the frequency differences of IL-10*T/*IL-10*C gene between schizophrenic patients and normal controls, respectively. We do suggest that further systematic studies including various clinical variables should be conducted.
