Hippocampal NG2+ pericytes in chronically stressed rats and depressed patients : a quantitative study
Objective: The suggested link between major depression disorder (MDD) and blood–brain barrier (BBB) alterations supports an impact on the neurovascular unit in this disease condition. Here we investigate how pericytes, a major component in the neurovascular unit, respond to stress, stress hormones, proinflammatory cytokine and depression. Method: Hippocampal sections of chronic unpredictable stres
