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.

Spinal cord injury often leads to permanent functional impairment. In a new study published in the journal Science researchers at Karolinska Institutet show that it is possible to stimulate stem cells in the mouse spinal cord to form large amounts of new oligodendrocytes, cells that are essential to the ability of neurons to transmit signals, and thus to help repair the spinal cord after injury.

The findings contribute to increased understanding about how our immune system responds against COVID-19 infection.

Women receiving fertility-sparing surgery for treatment of borderline ovarian tumours were able to have children, a study from Karolinska Institutet in Sweden published in Fertility & Sterility shows. Natural fertility was preserved in most of them and only a small proportion required assisted reproductive treatment such as in vitro fertilization. Survival in the group was also as high as in women who had undergone radical surgical for treatment of similar tumours.

The method simplifies and frees the testing from expensive reaction steps, enabling upscaling of the diagnostics. This makes the method particularly attractive for places and situations with limited resources, for repeated testing and for moving resources from expensive diagnostics to other parts of the care chain. The study is published in Nature Communications.
