Inflammation the culprit?

Individuals with schizophrenia, bipolar disorder, or major depressive disorder appear to have similarly elevated patterns of blood cytokine levels, according to Emory researchers. Cytokines are the key signaling molecules of the immune system. e results of the study, the rst broad-based analysis of cytokines in all three disorders, were published online in Molecular Psychiatry. In reviewing 69 studies of acutely ill patients and 46 studies of chronically ill patients, researchers sought to better understand what was happening in the patients’ immune systems.

“We know the immune system is important when looking at psychiatric disorders, but no one had really looked at this by comparing several disorders in one study, or by focusing on the phase of illness,” says

For example, one in ammatory cytokine, interleukin-6, was found to be elevated in all three disorders in both acute and chronic phases of illness.

By comparing these levels across diseases, the researchers were able to determine that the immune system is likely involved in psychiatric disorders for some patients and that treatment options may need to be more personalized. “Ultimately these ndings call for a need for more studies to determine exactly which individuals might bene t most from anti-in ammatory drugs,” says Goldsmith. ■
