The blood is the main source of studies on the immune system, despite the fact that most diseases are combated by immune cells in the body’s tissues. A new study from Karolinska Institutet and the University of Pennsylvania has identified which immune cells patrol the human body’s tissues and circulate back into the blood. The study, which is published in Cell, shows that not all T cells do this – some are found mostly in the blood where they constitute a unique part of our immune system.

Depressed children and teenagers have an increased risk of suffering from premature death and a wide range of illnesses later in life. That is according to a large observational study by researchers at Karolinska Institutet in Sweden. The findings highlight the need to look for other potential diseases following childhood or adolescent depression. Other psychiatric conditions, such as anxiety and substance misuse, can explain part of the association. The study is published in JAMA Psychiatry.

With clinical data from almost 3,000 diagnosed cases over a twenty-year time span, Katja Wyss at Karolinska Institutet’s Department of Medicine in Solna presents risk factors for malaria and new links between malaria and lymphoma – results that are of potential significance to people in many parts of the world.

Researchers at Karolinska Institutet in Sweden have come one step closer toward understanding why some people become seriously ill or die from a common bacterium that leaves most people unharmed. In a study published in The Lancet Microbe, the researchers linked RNA mutations within the bacterium Neisseria meningitidis to invasive meningococcal disease, marking the first time a non-coding RNA in a bacterium has been linked to disease progression.

DOAC (direct oral anticoagulant) pills are used in the treatment of atrial fibrillation by preventing blood clots. Even though blood clots are thought to contribute to complications from the new coronavirus infection, users of this class of drug do not seem to be protected against severe COVID-19, reports a large Swedish registry study from Karolinska Institutet published in The Journal of Internal Medicine.

Researchers at Karolinska Institutet have led an international team of scientists who have tested a vaccine for Crimean-Congo virus on primates for the first time. The vaccine provided protection against the virus, which can cause fatal haemorrhagic fever, and showed no serious side-effects. The study is published in the journal Nature Microbiology. The next big step will be to test the vaccine on humans.

Nasopharyngeal carcinoma (NPC), or nasopharynx cancer, is a malignant disease characterized by unique geographic distribution endemic to southern China, Southeast Asia, and the Middle East/North Africa. It is known that the interaction of Epstein-Barr Virus infection, environmental and lifestyle factors, and genetic susceptibility, contributes to NPC carcinogenesis.

Concerns have been raised that the use of a common group of medications called RAS inhibitors could facilitate SARS-CoV-2 infection, impact COVID-19 disease severity and worsen prognosis. However, in a new nationwide registry-based study from Karolinska Institutet, including almost 1.4 million patients, use of RAS inhibitors was not associated with increased risk of hospitalisation or death from COVID-19. The study has been published in the European Journal of Heart Failure.

Researchers at Karolinska Institutet set out to investigate potential reasons behind this disparity, such as the presence of other underlying diseases and smoking status. The study, which was published in Chest, shows that women have better survival rates after lung cancer surgery than men, independent of other factors.
