Interestingly, we found lower levels of VDBP in extracellular vesicles derived from plasma microglia (MDEVs) obtained from MDD patients, rhesus macaques with chronic‐glucocorticoid‐induced depression, and mice with LPS‐induced depression.[4] Additionally, decreased levels of VDBP were also detected in cerebrospinal fluid (CSF) samples collected from depressed rhesus macaques. The gene discussed is GC; the disease is depressive symptom measurement.
