New approach to drug discovery: pain medication with fewer side effects developed
People with chronic pain are often dependent on drugs from the class of opioids with sometimes considerable side effects. Accordingly, in recent years the search for safer alternatives has been the focus in drug discovery. As part of an international study led by MedUni Vienna, an opioid-like molecule has now been developed which, as shown in animal models, can effectively alleviate pain but with fewer undesirable side effects.

CBD as a painkiller: Efficacy not clinically proven
Cannabidiol (CBD) is marketed by some suppliers as a painkiller, e.g. for osteoarthritis of the knee. Animal experiments have shown that the substance, which is extracted from the hemp plant, has an anti-inflammatory and pain-relieving effect in arthritis. As pain researchers at MedUni Vienna were now able to show for the first time in humans, CBD is not effective as pain medication, even in high doses.

Catheter intervention for severe stroke life-saving
A large EU-funded study with the participation of experts from Graz has now shown that the removal of the causative blood clot with a catheter intervention in severe strokes can save lives. "Even in patients with severe strokes, treatment using a catheter to open the vessel occlusion is successful. In almost 20 percent of the patients treated, death or the need for nursing care could be prevented by a corresponding procedure," the Hamburg University Hospital (UKE) now reported.

Colorectal cancer surgery also advisable in patients with concomitant diseases
A research team at the Comprehensive Cancer Center of MedUni Vienna and Vienna General Hospital has published a study investigating the influence of chronic diseases on the occurrence of surgical or medical complications in oncological bowel surgery and how these affect long-term survival. It was found that although the number and severity of concomitant diseases influences the occurrence of medical or surgical complications, this does not have a negative impact on long-term survival in sicker individuals.

Breakthrough in the fight against resistance in metastatic breast cancer
A team of researchers at the Medical University of Vienna has discovered that dormant tumor cells surviving chemotherapy can be targeted through the inhibition of a specific protein called P-glycoprotein (P-gp). This discovery opens up new possibilities for delaying relapse and is particularly relevant for aggressive triple-negative breast cancer (TNBC), for which there are currently few effective treatments.

Small cell lung cancer: new approach to overcoming chemo-resistance
Small cell lung cancer accounts for about 15 percent of all diagnosed lung cancers and is still associated with a high mortality rate. SCLC tumours often develop resistance to chemotherapy and thus poor prognosis is due to tumour recurrence which occurs within only five to 14 months after initial diagnosis.

Autoimmune diseases: Protein discovered as potential new target for therapies
Autoimmune diseases are complex illnesses, the causes of which are diverse and have not yet been fully explained. A research team at MedUni Vienna has now discovered an immunoregulatory protein that could be linked to the development of autoimmune diseases such as rheumatoid arthritis. The identified component of the immune system is called "Rinl", which could provide a new target for the development of immunomodulatory therapies.

Gene Mutation in the Immune System: Anti-Diabetes Drugs Make Immune Cells More Effective Again
T cells are an essential component of the immune system - they fight foreign structures such as bacteria and viruses or cancer-related changes in cells. This defense reaction requires energy. Scientists led by the St. Anna Children's Cancer Research Institute, MedUni Vienna and the Marmara University Istanbul have now shown for the first time that a defect in the gene for the transcription factor NFATC1 leads to an immune defect with a disruption of metabolism in T lymphocytes.
