It appears that when our nervous system is developing, only the most viable neurons survive, while immature neurons are weeded out and die. This is shown in a ground-breaking discovery by researchers at Karolinska Institutet in Sweden. The results indicate that the long-standing neurotrophic theory, which states that chance determines which cells will form the nervous system, needs to be revised.

Three researchers at Karolinska Institutet have been appointed Wallenberg Scholar in 2019: Ernest Arenas, Sten Linnarsson, and Randal S. Johnson. The researchers – among the foremost in their field in Sweden – receive SEK 18 million each from the Wallenberg Foundations in the form of a five-year grant for free research.

Subpopulations of oligodendrocytes, myelin-producing cells in the brain that are targeted by the immune system in multiple sclerosis (MS), are altered in MS and might therefore have additional roles in the disease than previously described. The results are published in the journal Nature, in a study led by researchers at Karolinska Institutet in Sweden and University of Edinburgh in the UK.

A new study shows that there is a very limited regeneration of cells in the brain of patients diagnosed with multiple sclerosis (MS). These findings underline the importance of treating MS at an early stage of the disease progression, when the affected cells can repair the damage as they are not replaced by new ones. The results are published in the journal Nature by researchers from Karolinska Institutet and Uppsala University.

Although Parkinson’s disease is often associated with motor symptoms such as stiffness, poor balance and trembling, the first symptoms are often sensory and include a reduced sense of touch and smell. In a study on mice, researchers at Karolinska Institutet have now been able to identify neural circuits and mechanisms behind this loss of sensory perception. The study, which is published in the scientific journal Neuron, may open avenues to methods of earlier diagnosis.
