Ji-Seon Seo et al. found that p11 is highly expressed in ependymal cells, and is significantly decreased in patients with MDD, and in two mouse models of depression induced by chronic stress. These results identify a new role and a key molecular determinant for ependymal cell-driven CSF flow in mood disorders.
Researchers at Karolinska Institutet have identified a protein in the brain that is important both for the function of the mood-regulating substance serotonin and for the release of stress hormones, at least in mice. The findings, which are published in the journal Molecular Psychiatry, may have implications for the development of new drugs for depression and anxiety.
The Svenningsson lab was awarded a grant from the Swedish Research Council, to study Receptor-mediating mechanisms in Parkinson’s disease and depression.
