The early development of the immune system, antibiotics in dentistry and strengthened medical pedagogy. These are some of the research areas that Karolinska Institutet's new professors are interested in. On 14 October 2021, the annual inauguration ceremony was held in Aula Medica where 18 new professors were installed, and 12 adjunct professors and 2 visiting professors were welcomed to their new positions at the university.

Paul Ackermann is researching why problems often arise in the healing-process in tendons, ligaments, and other connective tissue in the locomotor system. His work can give rise to new therapies designed to help the injury to heal properly and prevent chronic pain and blood clots.

Less exercise and less rehab are the experiences reported by persons with Parkinson’s disease in a new study from Karolinska Institutet. The study sheds light on the situation during the first wave of the COVID-19 pandemic. According to Erika Franzén, professor and physiotherapist, especially women over 70 can be viewed as a risk group for reduced physical activity.

Statins are a recommended and common intervention for preventing cardiovascular events by reducing levels of lipoprotein cholesterol in the blood. During the pandemic, it has been debated whether statins influence the risk of death from COVID-19. Researchers at Karolinska Institutet have now conducted the largest population study to date in the field. The study, which is published in PLOS Medicine, indicates that statin treatment slightly lowers COVID-19 mortality.

Researchers from KTH Royal Institute of Technology, Karolinska Institutet and Karolinska University Hospital have developed a new kind of antibiotic-free protection for wounds that kills drug-resistant bacteria and induces the body’s own immune responses to fight infections. The technology is presented in the Journal of the American Chemical Society and could be an important tool in the fight against multidrug-resistant bacteria.

It remains a central challenge in psychiatry to reliably judge whether a patient will respond to treatment. In a new study published in the journal Biological Psychiatry, researchers from Karolinska Institutet in Sweden and the Max Planck Institute for Human Development in Germany show that moment-to-moment fluctuations in brain activity can reliably predict whether patients with social anxiety disorder will be receptive to cognitive behavioural therapy (CBT).

The ability to detect and react to the smell of a potential threat is a precondition of our and other mammals’ survival. Using a novel technique, researchers at Karolinska Institutet have been able to study what happens in the brain when the central nervous system judges a smell to represent danger. The study, which is published in PNAS, indicates that negative smells associated with unpleasantness or unease are processed earlier than positive smells and trigger a physical avoidance response.

Researchers at the Aging Research Center (ARC) have been awarded several substantial grants from Forte's annual open call for proposals. Out of the 32 projects, programmes and networks that received funding at KI, five were awarded to ARC.

A scientist at Karolinska Institutet reports that machine learning can be used to gain insights into molecular events that change the shape of proteins after they are made, regulating their ability to interact with each other. This suggests that artificial intelligence (AI) may allow us, in the future, to accurately simulate highly complex biological scenarios in silico as well as leverage this information for therapeutic intervention.

The 2021 Nobel Prize in Physiology or Medicine is about how people can feel temperature and touch. The discoveries explain basic functions in our lives and have opened doors to new treatments for pain, for example. We take it for granted, the fact that we can feel an icy wind, a hot plate or a hug, but how this actually works was unknown until it was discovered by the Nobel Laureates, a discovery made not so long ago.

Researchers at Karolinska Institutet have participated in a large international research project that has identified all cell types in the motor cortex, the part of the brain that controls movement. The research has resulted in a detailed cell atlas presented in a large special package of scientific articles in Nature today. The long-term goal of the collaboration is to create a cell atlas of the whole brain in order to increase knowledge of brain diseases and contribute to better treatments.

Scientists hope that tiny sacs of material excreted by cells – so-called extracellular vesicles – can be used to deliver drugs inside the body. Researchers at Karolinska Institutet now show that these nano-bubbles can transport protein drugs that reduce inflammation caused by different diseases. The technique, which is presented in Nature Biomedical Engineering, shows promising results in animal models.

The result showed no significant difference in mortality for the patients with pacemakers compared to those without. The study is published in the journal JACC: Cardiovascular Interventions.

It is well known that obesity affects the body's insulin production and over time risks leading to type 2 diabetes and several other metabolic diseases. Now researchers at Karolinska Institutet in Sweden have found further explanation for why fat cells cause metabolic morbidity. The study, published in Nature Medicine, may have an impact on the treatment of comorbidity in obesity with already available drugs.
