Using proteomics and other advanced tools of molecular biology, an international team of researchers led by a group from Karolinska Institutet have found a novel way to diagnose Alzheimer’s disease by blood analysis, with a potential to uncover the underlying cause of the disease and prevent its development.

In a recently published review article in Cell, researchers Jon Lundberg and Eddie Weitzberg at the Department of Physiology and Pharmacology at Karolinska Institutet summarize research in nitric oxide (NO) with a focus on what is happening right now.

Turning down the thermostat seems to make it harder for cancer cells to grow, according to a study in mice by researchers at Karolinska Institutet. The study, published in the journal Nature, found that chilly temperatures activate heat-producing brown fat that consumes the sugars the tumors need to thrive. Similar metabolic mechanisms were found in a cancer patient exposed to a lowered room temperature.

The students' association IFMSA runs the Vår hälsa brinner (Our health is on fire) campaign to raise awareness and educate about the health impacts of climate change. Students see a need to work concretely on the issue, not least during their medical training. They have made an alphabet series illustrating the impact of climate change on public health and hold educational workshops. During Politician's Week in Almedalen, they held a workshop and distributed posters with the alphabet.

To investigate the long-term benefit of hormone-lowering treatment, researchers at Karolinska Institutet have done a 20-year follow-up of premenopausal women with breast cancer. The study, published in the Journal of Clinical Oncology, indicates that the treatment provides protection even after a longer period of time and that different patients seem to benefit from different hormonal treatments.

Both children with type 1 diabetes and their closest family members are at increased risk of mental health problems compared with those without the disease, according to a large study by researchers at Karolinska Institutet published in the journal Diabetes Care. The findings underscore the need for psychological consulting for both children and their families in diabetes care.

Women with reduced kidney function received a diagnosis of chronic kidney disease to a less extent than men in the same situation. Women were also less likely to have their kidney function monitored, to visit a nephrologist and to use recommended treatments for chronic kidney disease. This according to a new study by researchers from Karolinska Institutet published in the Journal of the American Society of Nephrology.

The Swedish Media Council (Statens medieråd) in collaboration with NASP has produced a research review about suicide, internet-based communication about suicide and how suicidal individuals can be identified online.

In a new study, researchers at Karolinska Institutet show that the activation of specific cell surface proteins – cortisol, oestrogen and vitamin A – in mice with human neuroblastoma cells results in the neuronal differentiation of cancer cells which leads to reduced mortality. The results, published in the Journal of Experimental and Clinical Cancer Research, could, in the future, lead to a more gentle and effective treatment of this severe form of cancer in children.

Patients who have indwelling urinary catheters often suffer from urinary tract infections, which can be difficult to treat. Now, researchers at Karolinska Institutet have discovered that the synthetic peptide CD4-PP has a good bactericidal effect against urinary tract bacteria, even those resistant to antibiotics. The study, published in the journal Cellular and Molecular Life Sciences, opens up for new possible treatment methods.

In a study recently published in Cell Reports Methods, co- authors Björn Önfelt, Niklas Sandström and Valentina Carannante, researchers at SciLifeLab and the Department of Microbiology, Tumor and Cell Biology at Karolinska Institutet, describes a new miniaturized method for high-content screening combined with high-resolution imaging, all in the same microchip.

Professor Stefan Swartling Peterson at the Department of Global Public Health has been elected to the Swedish Crown Princess Couple's Foundation's expert council for the years 2022-2025.

Patients with multiple sclerosis (MS) treated with the drug rituximab had a significantly lower risk of relapse compared with MS patients receiving standard treatment. This has been shown in a phase 3 clinical trial by researchers at Karolinska Institutet and Danderyd Hospital in Sweden published in The Lancet Neurology. Rituximab is not approved as an MS drug, but has proven to be effective in smaller studies and is therefore largely prescribed “off label”.

Karolinska Institutet’s Silver Medal for 2018 is awarded to Fredrik Brolund and Lotta Widén Holmquist. The medals are awarded to those who have made a special contribution to supporting KI’s activities.

A study from Karolinska Institutet, among others, presents the theory that egg-sperm fusion, a crucial feature of sexual reproduction in plants and animals, may have originated from an ancient form of genetic exchange that involved the fusion of bacteria-like microorganisms called archaea. The results, published in Nature Communications, may open an entirely new perspective on the evolution of sex.

The Swedish Military Conscription Register contains data on some 2 million individuals. Conscripts underwent extensive testing, data that can be used in epidemiological research. Now researchers from Karolinska Institutet, Uppsala University and Lund University publish a review about the register in the European Journal of Epidemiology.

Distinct neuron types in the auditory organ are necessary for encoding different features of sound and relaying them to the brain. Researchers at Karolinska Institutet provide evidence of an early, neuronal activity-independent, emergence of the different subtypes of auditory neurons, prior to birth in mice. The findings have recently been published in Nature Communications.

The clinical outcome and severity of COVID-19 cannot be explained by a single factor like age, gender, or comorbidities. A new study from Karolinska Institutet in Sweden has identified potential determinants of COVID-19 severity at the cellular level using advanced systems biology analysis. The findings, published in the journal Cell Systems, offer insights into the metabolic tug-of-war in the human body and its association with disease severity.

For a drug to be effective and not harmful it needs to be administered at the right dosage. Certain enzymes in the body eliminate drugs, and the activity of these enzymes vary between individuals. Researchers at the Max Planck Institute for Evolutionary Anthropology in Germany and Karolinska Institutet in Sweden have studied two enzymatic variants which eliminate drugs less efficiently and show that the these enzyme variants are inherited from Neandertals.

The Board of Sven and Ebba-Christina Hagberg's foundation has decided to award Elizabeth Arkema and Marcus Buggert the foundations personal prize and a research grant, for a total of SEK 470,000 each.
