Rislenemdaz treatment in the lateral habenula improves despair-like behavior in mice.

ABSTRACT: The specific GluN2B antagonist rislenemdaz (Ris; a.k.a. MK-0657 and CERC-301) is in phase II clinical trial as an antidepressive drug, but the working mechanism for its antidepressant effects is not clearly understood. Given the important role of the lateral habenula (LHb) in the pathogenesis of depression and the fact that GluN2B-containing N-methyl-D-aspartate receptors and brain-derived neurotrophic factor (BDNF) are expressed in the LHb, we conducted a study to examine whether the LHb mediates Ris' antidepressant effects in a chronic restraint stress (CRS)-induced depressive-like mouse model. In this study, Ris was administered systemically or locally into the LHb. Short hairpin RNAs were used to knockdown BDNF in the LHb. Depressive-like behaviors were assessed with the open field tes
