Thanks to lab-grown miniature intestines, researchers at Uppsala University have successfully mapped how aggressive Shigella bacteria infect the human gut. The study opens the door to using cultured human mini-organs to investigate a wide range of other serious infections.
Researchers from Uppsala Antibiotic Center, Uppsala University and SciLifeLab describe a fundamental mechanism of antibiotic resistance. What happens in a bacterium that is resistant to the antibiotic fusidic acid? With a stop-motion movie at the atomic level, they can show that the resistance protein FusB works nearly like a crowbar.

That fit people have a reduced risk of premature death from various diseases is a recurring result in many studies. New research from Uppsala University shows that people with high fitness levels in their late teens also have a reduced risk of dying from random accidents. This suggests that the associations seen in previous studies have probably been misleading.
Even a few nights with insufficient sleep increases promote molecular mechanisms linked to a greater risk of heart problems. This has been shown in a new study in which the researchers investigated how sleep deprivation affects biomarkers (in this case proteins) associated with cardiovascular disease. The study was led from Uppsala University and is published in the journal Biomarker Research.
To provide the right treatment for MS, it is important to know when the disease changes from relapsing-remitting to secondary progressive, a transition that is currently recognised on average three years too late. Researchers at Uppsala University have now developed an AI model that can determine with 90 per cent certainty which variant the patient has.
The coffee from most of the coffee machines in workplaces contains relatively high levels of cholesterol-elevating substances. There is a big difference in comparison to coffee made in regular paper filter coffee makers, which filter out most of these substances.
The cells that make up the walls of the finest of all lymphatic vessels have a lobate, oak leaf-like shape that makes them particularly resilient to changes in fluid volume. A similar cell shape also supports mechanical stability in plants. This has been shown by researchers from Uppsala University in a new article published in the journal Nature.
The drug that slows down Alzheimer’s disease is already being used by more than 20,000 patients in 10 different countries – and could soon be available in Europe too. The success story is down to the two founders of BioArctic Lars Lannfelt and Pär Gellerfors and the company’s CEO Gunilla Osswald. Their achievement is now recognised by the Uppsala University Innovation and Entrepreneurship Award.
A recent study shows that computer algorithms can be used to find molecules that can be developed into anti-inflammatory drugs. In the article, the researchers also describe how the same strategy can be used to search through 10 sextillion alternatives to identify the best drug candidate.
People with the skin condition psoriasis often have invisible inflammation in the small intestine with an increased propensity for ‘leaky gut’, according to new research at Uppsala University. These changes in the gut could explain why psoriasis sufferers often have gastrointestinal problems and are more prone to developing Crohn’s disease.
A recent study shows that the Semliki Forest virus enters the central nervous system by first entering the cerebrospinal fluid and then binding to a specific cell type before penetrating deeper into the brain. This finding could potentially be used to develop the Semliki Forest virus as an agent for treating brain cancer. The study has been published in the journal Nature Communications.
New study: An app can help parents who are mourning the loss of a child. Parents who used the app for three months reported reduced symptoms of prolonged grief and post-traumatic stress, and also had fewer negative thoughts. Some parents thought that in future, the app should be offered early in the process of mourning. The study is published in the scholarly journal Cognitive Behaviour Therapy.
Researchers have analysed the effects of seven different hormone treatments for menopausal symptoms, and the risk of blood clots, stroke and heart attack. The risks differ depending on the active substance and how the medicine is taken. The study involves around one million women aged 50-58 and is the largest and most comprehensive study of currently prescribed hormonal substances in the world.
By exploiting the genetic variation in cancer cells, an already approved cancer drug demonstrated enhanced effects against cancer cells in specific patient groups. This is shown in a recent study from Uppsala University, published in the journal eBiomedicine. The findings suggest a potential for more individually tailored and more effective cancer therapies.
Researchers at Uppsala University and KTH Royal Institute of Technology have developed a new form of precision medicine, an antibody, with the potential to treat several types of cancer. Researchers have managed to combine three different functions in the antibody, which together strongly amplify the effect of T cells on the cancer tumour. The study has been published in Nature Communications.
All patients who have had a heart attack are typically treated using beta blockers. According to a Swedish study conducted earlier this year, this drug is unlikely to be needed for those heart patients who have a normal pumping ability. Now a sub-study at Uppsala University shows that there is also a risk that these patients will become depressed by the treatment.
More children have overweight in regions with high rates of single parenthood, low education levels, low income and high child poverty. The pandemic may also have reinforced this trend. This is shown by a study conducted by researchers at Uppsala University and Region Sörmland in collaboration with Region Skåne.
Researchers at Uppsala University have developed a clinical model that can accurately predict the risk of hip fractures in the elderly. The model is based on analyses of data from the entire Swedish population and can identify patients at high risk, without the need to measure skeletal strength. This can speed up the process for doctors and allow patients to receive preventive treatment.
The survival rate of men with prostate cancer who had their entire prostate gland removed immediately after the tumour was detected increased by 17 percentage points compared with those who did not have treatment until the tumour began to cause symptoms. On average, they also lived more than two years longer. These are the final results of a 30-year Scandinavian study led from Uppsala University.
What are the opportunities of using AI in healthcare? And what potential risks does it entail? These issues will be discussed during the Olof Rudbeck Day on 18 October. This year’s Rudbeck Prize winner, Ulf Gyllensten, will also give a lecture on his research into gynaecological cancer.
