Scientists from the Icahn School of Medicine at Mount Sinai have found a sexual dimorphism of depression based on the different expression of a molecule that could be developed as a therapeutic strategy. “There is a big sex difference in depression. Women are much more likely to have depression than men. They tend to have different subsets of symptoms. They tend to respond better to different antidepressants, and the depression tends to be more severe,” Orna Issler, the first author of the study and a postdoctoral researcher at the Nash Family Department of Neuroscience, Friedman Brain Institute, Icahn School of Medicine at Mount Sinai, told BioWorld. Their project, directed by Eric Nestler, a professor of neuroscience and director of the Friedman Brain Institute at the Icahn School of Medicine at Mount Sinai, had the aim to understand the biology of these sex differences of depression and to find therapeutic targets for it.
