There is a global trend of population aging and Xia Li has studied the phenomena from a molecular epidemiological point of view, with a focus on biological aging. As the number of elderly increases worldwide, there is a need for better data on assessment and prediction of aging risks independent of chronological age. This kind of data is needed together with genetic assessments in order to allow the use of precision medicine.

Researchers at Karolinska Institutet have analysed the presence of SARS-CoV-2-specific antibodies and memory cells of the immune system in young adults. The results, published in The Journal of Allergy and Clinical Immunology, show that over one in four had antibodies due to the infection. Fewer of these individuals had measurable levels of memory B and T cells compared with other age groups. The researchers will now study long COVID in young adults and the effects of vaccination on immunity.

As many as six photovoltaic power installations have now been put into operation on campus Solna. The installations are located on the roofs of, among others, Widerströmska huset, A Working Lab Innomedicum and the Berzelius Laboratory. Together, the solar cells cover an area of approximately 2,100 square metres and provide the campus area with renewable energy.

Circular RNAs’ role in cancer initiation and progression has gain a lot of interest recently, but there is no clear picture regarding their functional importance. New findings by researchers at Karolinska Institutet suggest that despite the relative abundance and differential expression, a substantial number of circular RNAs may represent “passenger molecules” with little impact on a cell, reflecting a stochasticity of the gene expression and splicing processes.

It’s described as a technological advance in computed tomography and the hope is that this imaging technique will eventually become hospital standard. At the end of October, a new type of CT scanner will be unveiled in MedTechLabs, an interdisciplinary centre set up by Karolinska Institutet (KI), the Royal Institute of Technology (KTH) and Region Stockholm. KI professor Staffan Holmin is one of the researchers behind the initiative.

Antibodies in the airways quickly wane after SARS-CoV-2 infection, but vaccination results in a strong increase in antibody levels, especially after two doses, according to a new study from Karolinska Institutet published in the journal JCI Insight. The results suggest that having a second dose of vaccine also after recovering from COVID-19 may be important for protecting against re-infection and to prevent transmission.

In partnership with several academic institutions in Sub-Saharan Africa as well as with Tinkr, a company specializing in innovation, they have co-created and started delivering on capacity building projects for health professionals to achieve the 2030 Agenda.

Research on the role of diet in the development of type 1 diabetes is generally of low evidence, but there are some high-quality studies indicating that longer breastfeeding and later introduction to gluten may reduce the risk of disease. That is according to a systematic review and meta-analysis of available research on foods that may be linked to the risk of developing the type 1 diabetes in childhood. The study by researchers at Karolinska Institutet is published in the journal EBioMedicine.

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.

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.
