20/09/2017The low uptake of flu vaccination among medical students and doctors is influenced by social attitudes say researchers. Despite a recommendation from the Chief Medical Officer for England that all healthcare workers are vaccinated annually, only 55 percent are protected against the spread of influenza, this could contribute to staff sickness and mortality among elderly patients.
20/09/2017Immunosuppressive regulatory T-cells play an important role in the functioning of adipose tissue. This is the discovery of scientists from the Helmholtz Diabetes Center (HDC) at Helmholtz Zentrum München and the Technical University of Munich (TUM). Their findings are published in the journal 'Cell Metabolism'.
19/09/2017To fight infections cells in the immune system play a dangerous game with their own genes. Damaging genes allows B cells to make antibodies that are specifically equipped to target to specific causes of illness, but damaging genes also puts them at risk of becoming cancerous.
13/09/2017By combining new system-biological analyses and advanced data analysis, researchers at Karolinska Institutet have been able to monitor the maturation process of the immune system of leukaemia patients who have undergone stem cell transplantation.
08/09/2017Adenoviral infections have a mild disease progression in healthy people, but it can be dangerous for immunocompromised people. If a patient is infected with the virus and gets a bacterial infection on top of it, it can lead to an excessive inflammatory response known as a cytokine storm, an overreaction by the immune system leading to high concentrations of proteins that promote inflammation.
06/09/2017Researchers at ETH Zurich, Empa and the Norwegian research institute SINTEF are pursuing a new approach to treating arthritis. This is based on a polysaccharide, a long-chain sugar molecule, originating from brown algae.
04/09/2017New research reveals the mechanisms behind the effects of chronic stress and tiny inflammations in the brain on fatal gut failure. Hokkaido University researchers revealed that fatal gut failure in a multiple sclerosis (MS) mouse model, EAE, under chronic stress is caused by a newly discovered nerve pathway.
01/09/2017There are many causes of myocarditis or inflammation of the heart muscle. Oftentimes, the culprits are viruses or bacteria and sometimes even an acute heart attack. Regardless of the cause, it creates a challenge for cardiologists: a diagnosis tends to be only nonspecific without a biopsy. A cardiac MRI and molecular imaging promise to provide assistance.
31/08/2017UT Southwestern Medical Center researchers report for the first time that tumors stressed by cancer immunotherapy release their mitochondrial DNA into nearby immune cells, triggering a host alert system.
29/08/2017Such detailed images of the pathogen that causes sleeping sickness inside a host are unique so far: They illustrate the manifold ways in which the parasites move inside a tsetse fly. A research team from the University of Würzburg's Biocenter has presented the images.
29/08/2017Omega-3 fatty acids, which we primarily get through eating fatty fish, have long been thought to be good for our health. Many dietary studies have suggested that high intake is associated with a reduced risk of various disorders. Clinical trials have also shown beneficial anti-inflammatory effects in patients taking omega-3 supplements.
23/08/2017Researchers at the University of Basel have developed a test to quickly and reliably diagnose a rare and severe immune defect, hepatic veno-occlusive disease with immunodeficiency. They reported on their findings in the "Journal of Clinical Immunology".
22/08/2017In its attempt to fight a serious bacterial infection, caused by listeria, for example, the immune system can become so over-activated that the resulting inflammatory response and its consequences can quickly lead to death.
17/08/2017Genetic differences in immune response demonstrate interaction of genetics and environment linked to disease risk.
17/08/2017For most of us, the flu is just the flu. We suffer through it for several days, and eventually bounce back. But for patients with multiple sclerosis (MS) and other neurological diseases, the flu can trigger a cascade of immune responses that result in a full-blown relapse of the disease.
16/08/2017Scientists from the University of Würzburg have synthesized a complex sugar molecule which specifically binds to the tumor protein Galectin-1. This could help to recognize tumors at an early stage and to combat them in a targeted manner
15/08/2017Researchers at Uppsala University have developed a new method for very rapidly determining whether infection-causing bacteria are resistant or susceptible to antibiotics. The findings have now been published in the US journal Proceedings of the National Academy of Sciences (PNAS).
04/08/2017A new study suggests that T cells, which help the body's immune system recognize friend from foe, may play an important role in Parkinson's disease (PD). The study, published in the journal Nature, was supported by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.
04/08/2017Freiburg neuroscientists develop new forms of diagnosis and therapy for temporal lobe epilepsy.
03/08/2017Perhaps you have come across the titles "Men are from Mars, women are from Venus" or "Why men don’t listen and women can’t read maps": just two of the many books and articles – some enlightening or amusing and others irritating – that theorise about fundamental differences between men and women.
03/08/2017Malaria was already widespread on Sardinia by the Roman period, long before the Middle Ages, as indicated by research at the Institute of Evolutionary Medicine of the University of Zurich with the help of a Roman who died 2,000 years ago.
27/07/2017A boosting skin vaccination with a biodegradable microneedle patch and protein constructed from sequences of influenza virus subtypes could improve the effectiveness of conventional influenza vaccines, according to a study led by Georgia State University.
19/07/2017Many animal species display flocking behaviour, but the fact that microorganisms do, is not as well known. Researchers at Lund University in Sweden have now shown that algae and bacteria form flocks at very low concentrations of individuals, a finding that could increase our future understanding of how the organisms infect their host animals.
04/07/2017Some insulin is still produced in almost half of the patients that have had type 1 diabetes for more than ten years. The study conducted by researchers at Uppsala University in Sweden has now been published online by the medical journal Diabetes Care.
03/04/2017The laboratory is one of the most important and pivotal bastions in patient care. In the laboratory, acute, chronic and genetic diseases are diagnosed, the progression of diseases such as diabetes is regularly checked or specialists look for biomarkers to adapt cancer therapies.
08/04/2016A diagnosis of diabetes often catches new patients off guard - for instance if they end up in the emergency room suffering from metabolic decompensation. Children are often affected by this. Their immune system destroys the insulin-producing cells in the pancreas early on in their lives, thus causing type 1 diabetes.
01/06/2015A tumor is as unique as the person who is affected by it. For a long time, it was assumed this would make treatment more difficult since cancer drugs are not able to be one hundred percent effective in targeting the affected cells. In this interview with MEDICA.de, Professor Ugur Sahin explains why it is precisely these individual mutations that make him hopeful for a new type of therapy.
22/08/2014Besides antibiotics, vaccines may be the most important development in medicine: they protect us from diseases by “introducing” our immune system to pathogens. This way, a small injection saves us from severe and potentially mortal courses of disease.
01/08/2014Bacteria lurk everywhere: on the skin, in the intestines and in every puddle. Most of them that are hanging out in the human body are good bacteria. But not all of them. Those pathogens that exhibit resistance and are thus very hard to combat are the most dangerous kind. Their spread threatens people all over the world.
22/01/2014It guards the body but can become its enemy: the immune system defends us from intruding pathogens; it is also able to cause severe diseases if it falsely recognizes the body itself as a threat. Molecular receptors in the whole body enable the immune system to “sense” what happens within.
