Background: This study addresses the expression of the glycosylated proteins known as advanced glycation end products (AGEs), the calcium binding protein S100B and the apoptotic parameters cytochome c and caspase-3 activity in peripheral lymphocyte cytosolic extracts from a sample of bipolar disorder (BD) patients and healthy (control) subjects. Methods: Cross-sectional study of 35 patients with a clinical diagnosis of bipolar disease (10 euthymic, 12 depressed, 13 manic) and 10 healthy control subjects. Lymphocytes were used as a surrogate model in BD diagnosis and treatment. AGEs and S100B in lymphocyte cell extracts were measured by commercially available enzyme-linked immunosorbent assay. Results: AGEs were lower in all BD patients compared to healthy subjects. Depressed patients had approximately two-fold higher S100B levels compared to healthy subjects. Manic and depressed BD patients had increased superoxide dismutase mRNA levels. Apoptosis as measured by BAX/Bcl2 ratio, cytochrome c release, caspase-3 activity was increased in manic and depressed patients compared to healthy subjects. In the depressed patients, S100B levels correlated with cytochrome c release. Conclusions: In conclusion, our study shows decreased AGEs and increased S100B levels and caspase downstream apoptosis in peripheral lymphocytes of BD patients that may underlie disease etiopathogenesis. |
