Psilera Inc. has announced animal findings for its first cohort of drug candidates designed and synthesized in-house showing that they are non-hallucinogenic. This group includes six patent-pending compounds with novel structural features across four compound families.

The U.S. FDA granted Sooma Oy breakthrough device designation for its patient-administered neuromodulation device to treat depression. Sooma Depression Therapy uses a mild electrical current to stimulate targeted brain areas, resulting in a significant improvement in depressive symptoms.

Artificial intelligence (AI) startup Voice Health Tech has developed a model that can diagnose depression.

Researchers at the Dana-Farber Cancer Institute have been able to identify proteins that were released from muscles during exercise in relatively small quantities. Using their method, the team was able to demonstrate that the neurotrophic factor prosaposin was produced during exercise. Prosaposin is “a well-known CNS neurotrophic factor, but has never been seen to come out of muscle or fat,” Bruce Spiegelman told BioWorld. Spiegelman is a researcher at the Dana-Farber Cancer Institute and Stanley J. Korsmeyer Professor of Cell Biology and Medicine at Harvard Medical School.

Major depressive disorder (MDD) was linked to impaired neural connectivity caused by astrocyte dysfunction, according to a study from the Southern Medical University in Guangzhou in collaboration with the University of Hong Kong.

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.
