Nataliia Petryk ran a private clinic in Kyiv helping women give birth when she was forced to flee Ukraine when Russia invaded her country. By following a call by the European Research Council for EU teams to take in Ukrainian scientists, she is now able to conduct research to prevent miscarriage at Karolinska Institutet. Her experience is an example of how science knows no borders.

Welcome to Marcus Dahlquist's doctoral thesis defence on Friday 27 January 2023 at 9:00 in aulan, Danderyds hospital.

High levels of mucosal IgA antibodies in the airways protect against SARS-CoV-2 infection for at least eight months. Omicron infection generates durable mucosal antibodies, reducing the risk of re-infection. These are the findings of a study published in The Lancet Infectious Diseases by researchers at Karolinska Institutet and Danderyd Hospital in Sweden. The results raise further hope for the feasibility of future nasal vaccine platforms to protect against infection.

The world is quickly approaching a tipping point when it comes to preventing many of the devastating consequences of the climate crisis. We see the effects of it on the environment and our planet, and in recent years the discussion on the effects of climate change on human health has grown. But what do we know about the effects on children? Doctoral student Daniel Helldén, presents at the Global Child Health conference organized by University of Calgary.

Proteins do not have a single shape, but are more like dynamic robots. But – how do they actually move? And what does this tell us about their function? Laura Orellana describes the movement of proteins using computer simulations – and has discovered a new drug target for glioblastoma brain tumours.

High levels of uric acid in midlife may significantly raise the risk for a serious type of irregular heartbeat in the decades that follow, even in people without traditional risk factors, new research from Karolinska Institutet published in the Journal of the American Heart Association shows.

Being affected by several cardiometabolic diseases such as diabetes, heart disease and stroke, is linked to a greatly increased risk of dementia and Alzheimer’s disease. A new twin study by researchers from Karolinska Institutet suggests that the same genes may be behind the risk of both cardiometabolic diseases and dementia. The findings have been published in European Heart Journal.

Proteins can make any inventor green with envy. It is proteins that make the body work. But when these same super-substances make mistakes, we may get sick with things like cancer or Alzheimer's disease. The job of researchers is to sort out the proteins when they malfunction.

Alzheimer disease begins decades before any symptoms, such as memory loss, start to show. Consequently, early diagnosis increases the chances of slowing the disease down with drugs. A new study on an inherited form of the disease shows that a protein called GFAP is a possible biomarker for very early stages of the disease. The study, conducted by researchers at Karolinska Institutet and published in the journal Brain, could one day lead to an earlier detection of this serious and common disease.

Congratulations to Professor Marie Löf at the Department of Biosciences and Nutrition who has received MSEK 4.9 from the Kamprad Family Foundation for Entrepreneurship, Research & Charity.

The Vascular Surgery Group celebrated it’s 50 years anniversary in late October last year. The exact birthday of the lab is difficult to set. Nevertheless, it was not difficult to select 1972 as an appropriate starting point when Siw Frebelius joined Jesper Swedenborg and they together initiated the foundation of a research group which has survived throughout 50 years. 

Researchers at Karolinska Institutet, the Centre for Imaging Research (CIR), SciLifeLab, and RISE have together received a grant of over SEK 100 million from the European Commission's Digital Europe programme.

Cluster headache, sometimes known as “suicide headache”, have been described as a predominantly male disease. New research from Karolinska Institutet now shows that women who have the disease are more affected in their daily lives. They have longer periods of pain, a higher frequency of related symptoms, use more prophylactic medicine and take more sick leave. The results are published in two studies in the journal Neurology, the medical journal of the American Academy of Neurology.

Researchers from the Division of Neurogeriatrics, NVS, has had an article published in EMBO Molecular Medicine. They have completed an active vaccination study in a mouse model with inherited small vessel disease called CADASIL with the aim to investigate whether vaccination can repair damaged vessels by clearing them from toxic protein Notch3 aggregates. These aggregates are present in CADASIL patients and in this mouse model.

Researchers at Karolinska Institutet, Karolinska University Hospital and Cellevate AB, have received almost 5 million SEK from Vinnova, to investigate how stem cells interact with their environment. The goal is to develop more effective production of stem cell therapies, and eventually contribute to better treatment of public diseases such as heart failure and diabetes.

Patients with treatment resistant depression have a 23 per cent higher risk of death than other depressed patients. They also have twice as much outpatient care and spend three times the number of days in inpatient care. These are findings of a new study published in JAMA Psychiatry by researchers from Karolinska Institutet and elsewhere, who conclude that it is important to identify patients at risk of developing treatment resistant depression.
