He is survived by his wife Kristina, his children Karin and Anders and grandchildren. Wed, 06 Nov 2024 16:05:03 +0100 https://news.ki.se/new-study-on-micrornas-could-lead-to-better-fertility-treatment Researchers at Karolinska Institutet have mapped how small RNA molecules, such as the recently Nobel Prize-awarded microRNAs, control cell development in the human embryo during the first days after fertilisation. The findings, published in Nature Communications, may eventually contribute to improved fertility treatment. Wed, 16 Oct 2024 11:00:08 +0200 https://news.ki.se/identification-of-a-direct-progenitor-population-for-differentiation-to-insulin-producing-cells The deficiency of functional insulin-producing cells is a common feature of type 1 and late-stage type 2 diabetes. Previous studies have suggested that mammals have very limited capacity for regeneration of insulin-producing cells, but researchers at Karolinska Institutet have found how zebrafish can form new cells and thereby provide clues to possible future possibilities in diabetes. The study is published in the scientific journal Science Advances. Mon, 21 Aug 2023 07:27:17 +0200 https://news.ki.se/map-of-spinal-cord-formation-gives-new-knowledge-on-diseases-of-the-nervous-system Researchers at Karolinska Institutet have mapped how cells in the human spinal cord are formed in the embryo and what genes control the process. Their findings can give rise to new knowledge on how injury to and diseases of the spinal cord arise and how they can be treated. The study has been published in the journal Nature Neuroscience. Wed, 26 Apr 2023 13:56:41 +0200 https://news.ki.se/new-technique-allows-mapping-of-mechanisms-of-tissue-development In a new study published in Science, researchers at Yale University, in collaboration with researchers at Karolinska Institutet, have developed a technique that gives very precise information about the location of activated and inactivated genes in a specific tissue. This can provide important knowledge about how different tissues develop and how epigenetic regulation contributes to the development of disease. Thu, 10 Feb 2022 20:00:06 +0100 https://news.ki.se/new-study-reveals-how-the-lungs-immune-cells-develop-after-birth From our first breath, our lungs are exposed to microorganisms, such as bacteria and viruses. Thanks to immune cells in the lungs, so-called macrophages, we are protected from most infections at an early age. In a new study published in the Journal of Experimental Medicine, researchers from Karolinska Institutet show how lung macrophages develop; new findings that can help to reduce organ damage and that are significant for the continued development of important lung disease treatments. Wed, 12 Jan 2022 16:00:07 +0100 https://news.ki.se/problems-in-synapse-connection-sites-found-in-rare-neurodevelopmental-disorders Researchers at Karolinska Institutet describe molecular and cellular consequences of unique genetic mutations affecting the CASK gene which has been implicated in various neurodevelopmental disorders. Notably, the results indicate differences in the development of presynapses of inhibitory neurons in individuals with specific mutations. The findings elucidate key mechanisms during early neuronal maturation and may help to define targets for future drug discoveries for these disorders.

The study demonstrates how important the family environment is, not just during early infancy but also throughout adolescence.

Thu, 16 Jan 2020 15:48:38 +0100 https://news.ki.se/250000-developmental-cells-sequenced Researchers from the global Human Cell Atlas Consortium report that they have sequenced a quarter of a million separate cells that are of importance for early development of organs such as the liver, skin and kidneys. Sten Linnarsson at Karolinska Institutet is participating in the project. Thu, 08 Mar 2018 15:59:06 +0100 https://news.ki.se/cell-model-of-the-brain-provides-new-knowledge-on-developmental-disease By reprogramming skin cells into nerve cells, researchers at Karolinska Institutet are creating cell models of the human brain. In a new study published in Molecular Psychiatry the researchers describe how cells from patients with the severe developmental disease lissencephaly differ from healthy cells. The method can provide vital new knowledge on difficult-to-study congenital diseases.
