Obesity and major mood disorders (MMD), namely bipolar disorder and major depressive disorder, have drastically increased in recent years in the United States adolescent population. Evidence indicates higher levels of circulating pro-inflammatory cytokines in both obesity and mood disorders. The effect of adipokines released by adipose tissue on the central nervous system (CNS) and inflammation in the progression of mood disorders remains understudied. In our study, we aimed to elucidate mediators between adipose and neural tissue that may link progression of mood disorders and metabolic imbalance. We hypothesized that adipose tissue can produce and secrete signaling molecules such as neuroadipokines or inflammatory cytokines that influence CNS function. We investigated 1) production and secretion of glia maturation factor ß (GMFß) in WT and Aldh1a1-/- adipocytes and 2) inflammatory and anti-inflammatory factors in mood disorder patients’ serum and their cumulative inflammatory impact on adipocytes measured by NF-kB, a master transcriptional regulator of inflammation. We found that GMFß is produced and secreted by adipocytes and its expression depends on aldehyde dehydrogenase 1A1. Thus, GMFß is a neuroadipokine that can function in adipose as well as neural tissue. In addition, we found increasing variability of NF-kB and its target cytokines if severity of MMD in patients increases. These data suggest that both suppression and increases in inflammation may influence MMD progression that warrants studies in specific MMD populations.
