An international metastudy led by researchers at Karolinska Institutet has identified a specific gene variant that protects against severe COVID-19 infection. The researchers managed to pinpoint the variant by studying people of different ancestries, a feat they say highlights the importance of conducting clinical trials that include people of diverse descents. The results are published in the journal Nature Genetics.

Researchers at Karolinska Institutet and the Icahn School of Medicine at Mount Sinai in USA, have mapped how genes work together to cause cardiovascular disease. The study published in Nature Cardiovascular Research, suggests that that nearly 60 percent of the risk associated with coronary artery disease may be explained by regulatory gene networks.

Hi Linn Öijerstedt, PhD student at the Division of Neurogeriatrics, NVS. On January 20 you will defend your thesis ”Biomarkers in frontotemporal dementia : findings from the GENFI study”, what's the main focus of the thesis?

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.

Anita Göndör’s group has identified a new mechanism underlying the pathological over-expression of cancer genes. The results, which are published in Nature Communications show that signals in the environment of the cancer cell exploit a CTCF-bound super-enhancer to recruit cancer genes to the nuclear pore in a multistep process that involves a non-coding RNA. This discovery provides new opportunities for targeting overactive cancer genes without interfering with their functions in normal cells.

In a new study, researchers at Karolinska Institutet have identified the presence of a specific connection between a protein and an lncRNA molecule in liver cancer. By increasing the presence of the lncRNA molecule, the fat depots of the tumor cell decrease, which causes the division of tumor cells to cease, and they eventually die. The study, published in the journal Gut, contributes to increased knowledge that can add to a better diagnosis and future cancer treatments.

Schizophrenia and eating disorders (EDs) are complex traits with considerable somatic and psychiatric morbidity, affecting 0.4-1% and 9% of the population, respectively. Risk for both is predominantly from genetic sources – 64-81% for schizophrenia and 41-83% for EDs. Despite distinct diagnostic criteria and few common symptoms, significant genetic correlations between schizophrenia and anorexia nervosa (AN) have been identified in several recent genomic studies.

The research committee at the Swedish Cancer Society has just named Henrik Grönberg “Cancer Researcher of the Year 2022” for his efforts in prostate cancer research. Henrik Grönberg’s research has contributed to earlier detection of prostate cancer and that unnecessary examinations can be avoided.

People with type 2 diabetes have an increased risk of stroke and slower recovery from it. Now, researchers at Karolinska Institutet have shown that neurological recovery from stroke is significantly improved in mice with obesity and diabetes who achieve weight loss to the extent that glucose metabolism returns to normal levels. The results are published in the scientific journal Cardiovascular Diabetology and may have clinical relevance for stroke rehabilitation in type 2 diabetes.

KI researcher Marcus Buggert has been awarded the prestigious ERC Starting Grant for his research on human cell-mediated immunity against virus diseases. In all, the European Research Council through this call will invest EUR 619 million in 397 young research leaders.

Very few proteins in the body have a change that makes them unique compared to the corresponding proteins in Neanderthals and apes. Researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden have now studied one such protein, glutathione reductase, which protects against oxidative stress. They show that the risk for inflammatory bowel disease and vascular disease is increased several times in people carrying the Neanderthal variant.

Researchers at Karolinska Institutet have charted the number of healthcare workers in Stockholm who were on duty during the first wave of the pandemic despite being infected with SARS-CoV-2, having been asymptomatic at the time. The results of the study, which is published in the journal PLOS ONE, present very low figures but the researchers believe that this could still have affected the spread of infection.

Last week the Department of Global Public Health in cooperation with War Child Sweden and the Swedish Red Cross University College hosted a guest lecture with Professor Mark Jordans. In his presentation, Professor Jordans presented interventions and evidence on how to promote the mental health and well-being of children in settings made fragile by armed conflicts.

A receptor activated by substances formed from omega-3 fatty acids plays a vital role in preventing inflammation in blood vessels and reducing atherosclerosis, a new study from Karolinska Institutet published in The Journal of Clinical Investigation reports. The discovery can pave the way for new strategies for treating and preventing cardiovascular disease using omega-3 fatty acids.

Use of assisted reproductive techniques (ART) does not lead to poorer mental health in children across adolescence and young adulthood, according to a large observational study led by researchers at Karolinska Institutet. The study, published in JAMA Psychiatry, found a slightly higher risk of obsessive-compulsive disorder for those born after ART but this was explained by parental background factors.

Instead of searching for proteins that the immune system reacts against in a specific autoimmune disease, researchers have taken the opposite approach to find diseases linked to a certain protein. By searching among patients with various skin diseases, they identified a disease linked to autoimmunity against the skin protein TGM1. The strategy, which is presented in the journal PNAS, can facilitate the diagnosis and treatment of autoimmune diseases.

Anna Kågesten and Karin Båge, Assistant Professor and PhD-student respectively, at the Department of Global Public Health, have co-authored a newly published report for the Expert Group on Aid Studies. The report aims to improve the understanding of norms and values that undermine vs. support sexual and reproductive health and rights (SRHR), and to identify gaps and possibilities for Swedish development cooperation to find ways to relate to these norms and values.

Endothelial cell dysfunction is a well-established response to cardiovascular disease risk factors, such as smoking and obesity. A new study from Karolinska Institutet show that an individual’s cardiovascular disease risk was linked to the levels of endothelial proteins found in the blood. The study was recently published in Arteriosclerosis, Thrombosis, and Vascular Biology, ATVB Journal.
