Exact mechanism of serotonin transport in nerve cells researched
Drugs known as antidepressants target the serotonin transporter in nerve cells and are among the most commonly prescribed medicines worldwide, but are sometimes associated with significant side effects. As part of a study, a research group led by Thomas Stockner from MedUni Vienna identified the basic principles of serotonin transport and thus created a possible basis for the development of novel drugs with improved selectivity and with fewer undesirable effects.

Role of the GCP signalling pathway in ageing identified
With increasing life expectancy, old age is becoming an ever larger part of the human lifespan. During ageing, the way cells function changes, which sometimes has drastic consequences for the body. A recent study published in the journal "Nature Aging", led by Josef Penninger, Professor of Personalised Medicine at MedUni Vienna, reveals the crucial role of a previously unknown lipid metabolic pathway in ageing, in particular its impact on muscle health and glucose control.

Protein complex discovered to control DNA repair
The repair of damage to genetic material (DNA) in the human body is carried out by highly efficient mechanisms that have not yet been fully researched. A scientific team led by Christian Seiser from MedUni Vienna's Center for Anatomy and Cell Biology has now discovered a previously unrecognised control point for these processes.

Synapses Brought to the Point
Synapses Brought to the Point
Scientists unravel structure and function of important inhibitory synapses in the cerebellum Whether picking up a small object like a pen or coordinating different body parts, the cerebellum in the brain performs essential functions for controlling our movement. Researchers at the Institute of Science and Technology Austria (ISTA) investigated how a crucial set of synapses between neurons within it functions and develops.

Possible trigger of chronic inflammatory bowel disease identified
As the cause of chronic inflammatory bowel diseases (IBD) such as Crohn's disease or ulcerative colitis is not yet known, treatment for sufferers is currently aimed at alleviating the often agonising symptoms. The discovery by a MedUni Vienna research team that the trigger for IBD could be found on the surface of intestinal epithelial cells provides a new potential starting point for the development of therapeutic measures.

Stranger than Friction: A Force Initiating Life
Scientists examine how friction forces propel development in a marine organism As the potter works the spinning wheel, the friction between their hands and the soft clay helps them shape it into all kinds of forms and creations. In a fascinating parallel, sea squirt oocytes (immature egg cells) harness friction within various compartments in their interior to undergo developmental changes after conception.

The Snail or the Egg?
The Snail or the Egg?
How marine snails switched from laying eggs to giving birth Animals reproduce in one of two distinct ways: egg-laying or live birth. By studying an evolutionarily recent transition from egg-laying to live-bearing in a marine snail, collaborative research by the Institute of Science and Technology Austria (ISTA), the University of Sheffield, and the University of Gothenburg has shed new light on the genetic changes that allow organisms to make the switch.

Multiple sclerosis: Possible basis for vaccine researched
Multiple sclerosis: Possible basis for vaccine researched
Multiple sclerosis (MS) is a chronic inflammatory autoimmune disease in which the Epstein-Barr virus (EBV) is thought to play a role that has not yet been fully clarified. In particular, it was previously unclear why almost all people are infected with EBV in the course of their lives, but the virus only triggers MS in a small number of people.

The Pedigree of Brain Cells
The Pedigree of Brain Cells
New study explains development of the mammalian superior colliculus The superior colliculus in the mammalian brain takes on many important tasks by making sense of our environment. Any mistakes during the development of this brain region can lead to severe neurological disorders. ISTA scientist Giselle Cheung and colleagues have now, for the first time, delineated the pedigree and origin of nerve cells that make up the superior colliculus.

Breakthrough in understanding the genetic basis of immune responses
A US research team with significant involvement from MedUni Vienna has analysed the molecular structures of human T cells, providing an unprecedentedly detailed description of how the immune system works. The results, which have now been published in the top journal "Nature", could help to overcome the limitations of current immunotherapies and find new approaches for the future treatment of a variety of diseases such as autoimmune diseases or cancer.

Floral Time Travel: Flowers Were More Diverse 100 Million Years Ago Than They Are Today
Angiosperm flowers reached their greatest morphological diversity early in their evolutionary history An international team of researchers around botanists at the University of Vienna, Austria, has now analyzed the morphological diversity of fossilized flowers and compared it with the diversity of living species.

Researchers at TU Graz Decipher Enzyme Scissors of Intestinal Microbes
Flavonoids & Co: Microorganisms in the human gut utilise so-called beta-elimination to break down plant natural products and thus make them available to humans. Fruit and vegetables contain a variety of plant natural products such as flavonoids, which give fruits their colour and are said to have health-promoting properties.

’Zoom Fatigue’: Exhaustion caused by video conferencing proven on a neurophysiological level for the first time
By Philipp Jarke Using EEG and ECG data, researchers at the University of Applied Sciences Upper Austria and Graz University of Technology were able to prove that video conferences and online education formats lead to greater fatigue than face-to-face alternatives. Following the COVID-19 pandemic, the increase in virtual interactions has created a new challenge: fatigue caused by video calls, also known as Zoom fatigue or videoconference fatigue.

Why parents should sing to their babies
Why parents should sing to their babies
Play songs shape the language skills of young children Parents often sing lullabies or happy play songs to their babies. But how do babies react to these everyday songs - and what role do they play in child development? A research team from the University of Vienna in collaboration with the University of East London investigated these questions in a recent study.

Microbiome of Fruit and Vegetables Positively Influences Diversity in the Gut
Microbiome of Fruit and Vegetables Positively Influences Diversity in the Gut
In a meta-study, a research team from the Institute of Environmental Biotechnology at TU Graz has provided evidence that the consumption of fruit and vegetables contributes positively to bacterial diversity in the human gut. Bacterial diversity in the gut plays an important role in human health. The crucial question, however, is where are the sources of this diversity? It is known that an important part of the maternal microbiome is transferred to the baby at birth, and the same happens during the breastfeeding period via breast milk.
