A recent study published in Indoor Air by Antonio Rothfuchs et al, is the first to demonstrate active SARS-CoV-2 in air. Infectious SARS-CoV-2 was recovered from the air in rooms occupied by COVID-19 patients. This result strongly supports the aerosol route of transmission for SARS-CoV-2 and urges the revision of infection control frameworks for COVID-19 to include airborne transmission.

Researchers at Karolinska Institutet have identified a new antidiabetic substance that preserves the activity of insulin-producing beta cells and prevents high blood glucose in mice. The study is published in the journal Science Translational Medicine.

Collections of human remains were once a common feature of medical universities, where they were used for both education and research. Karolinska Institutet itself was home to some 800 skulls and other bones, which were kept in boxes stored in specially designated places – where they have remained untouched for decades. This – and more besides – was the subject of a seminar arranged by KI’s Ethics Council on Tuesday.

Many thanks to all of you that joined our meeting and a special thanks to the students for their nice presentations and the good discussions that followed.

A new study shows how antibodies select the antigens that they bind to, as they navigate the surface of pathogens like coronaviruses. Researchers from KTH Royal Institute of Technology and Karolinska Institutet have created a model that suggests the migration of these pathogen hunters may be akin to the random movements of a child playing on stream laden with stepping stones.

The Svedberg prize 2022 is awarded to Ben Murrell, Department of Microbiology, Tumor and Cell Biology, for his work characterizing antibody responses to viruses, especially the virus SARS-CoV-2.

Researchers at Karolinska Institutet have developed a novel strategy for identifying potent miniature antibodies, so-called nanobodies, against emerging SARS-CoV-2 variants. The approach led to the discovery of multiple nanobodies that in cell cultures and mice effectively blocked infection with different SARS-CoV-2 variants. The findings, which are described in the journals Nature Communications and Science Advances, could pave the way for new treatments against COVID-19.

A new study by researchers at Karolinska Institutet shows that the local activity of the signaling molecule Rac1 controls cycles of microscopic protrusions and retractions of the cell membrane. The cell uses these cycles to sense its surroundings, which among other things affects the cell's ability to move. Understanding of the cellular and molecular mechanisms that control cell movements, can help us to develop better diagnostics and treatment of various diseases such as cancer.

The visit was made in conjunction with National Vaccination Week, which has the aim of achieving more people being vaccinated against Covid 19.

Late last year, preliminary studies revealed that the fast-spreading Omicron SARS-CoV-2 variant was likely to evade COVID-19 antibodies but, in many people, less so than expected. Now one of those studies from Karolinska Institutet has been published in the prestigious journal The Lancet Infectious Diseases. KI researcher Ben Murrell explains the findings and recalls the rush to understand the new variant.

People who were bedridden for at least a week due to COVID-19 were more likely to experience anxiety and depression for up to 16 months after the infection, compared with those who only had mild symptoms or were never infected. That is according to a large study based on data from six countries and conducted by an international team of researchers including those from Karolinska Institutet and the University of Iceland. The findings are published in The Lancet Public Health.

There is a lack of understanding as to why some people suffer from long-lasting symptoms after COVID-19 infection. A new study from Karolinska Institutet in Sweden, the Helmholtz Center Munich (HMGU) and the Technical University of Munich (TUM), both in Germany, now demonstrates that a certain type of immune cell called macrophages show altered inflammatory and metabolic expression several months after mild COVID-19. The findings are published in the journal Mucosal Immunology.

The p53 protein protects our cells from cancer and is an interesting target for cancer treatments. The problem is, however, that it breaks down rapidly in the cell. Researchers at Karolinska Institutet have now found an unusual way of stabilising the protein and making it more potent. By adding a spider silk protein to p53, they show that it is possible to create a protein that is more stable and capable of killing cancer cells. The study is published in the journal Structure.

Parkinson's disease (PD) is a progressive and complex disorder that affects multiple parts of the brain but also other organ systems. Symptoms start gradually, sometimes with a barely noticeable tremor in just one hand. Tremor is common, and the disorder also commonly causes stiffness and slowing of movements. More than 10 million people worldwide are living with PD and the incidence increases dramatically with age.

Women who have had one ovary surgically removed (unilateral oophorectomy) are less likely to become pregnant after in vitro fertilisation and give birth to fewer babies than women with both ovaries. That is according to an extensive meta-analysis published in the journal Fertility and Sterility by researchers at Karolinska Institutet.

Global warming is likely to increase the number of people requiring hospitalization due to critically low sodium levels in the blood, a condition known as hyponatremia. A new study from Karolinska Institutet projects that a temperature rise of 2 degrees Celsius would increase the burden on hospitals from hyponatremia by almost 14 percent. The findings are published in the Journal of Clinical Endocrinology and Metabolism.
