Peptides vs. superbugs


Several peptides have an antibacterial effect - but they are broken down in the human body too quickly to exert this effect. Empa researchers have now succeeded in encasing peptides in a protective coat, which could prolong their life in the human body. This is an important breakthrough because peptides are considered to be a possible solution in the fight against antibiotic-resistant bacteria.

Dying tumour cells release intracellular ions


Researchers at the National Cancer Institute in the USA and the Babraham Institute, UK, have discovered how a mineral ion leaked from tumour tissue as it dies acts to stop the work of anti-tumour immune cells. This discovery provides a new approach in the development of treatments to engage the immune system in the fight against cancer.

Poison in the brain


The following factors facilitate the formation of putatively toxic structures in the neuronal nuclei of Alzheimer's patients. Spherical structures in the nucleus of nerve cells, so-called nuclear spheres, are suspected to trigger Alzheimer's disease.

Belgian scientists discover missing link in septic shock


Researchers at VIB and Ghent University have discovered an important mechanism of sepsis, an overreaction of the body’s immune system to an infection. In this condition, the brain is unable to curb an inflammatory response, causing organ failure or ‘septic shock’.

Predicting the severity of multiple sclerosis


Cells in the immune system of patients with multiple sclerosis behave differently from those of healthy individuals. Researchers at Linköping University in Sweden have exploited this difference to develop a method that can predict disease activity in multiple sclerosis.

Penn software helps to identify course of cancer metastasis


Individual cells within a tumor are not all the same. This may sound like a modern medical truism, but it wasn't very long ago that oncologists assumed that taking a single biopsy from a patient's tumor would be an accurate reflection of the physiological and genetic make-up of the entire mass.

Response to house dust mites is age-dependent


In adults with a house dust mite allergy, a cascade of inflammatory signals on the surface of the airways leads to airway remodeling. This process cannot be influenced by standard cortisone therapy. Researchers at Helmholtz Zentrum München and the Technical University of Munich have reported these findings.

Progress in vaccination against vespid venom


Especially in late summer, apprehension about wasp stings increases amongst allergy sufferers. So-called hyposensibilisation therapy can help, but it is linked to a heavy burden on patients and health insurers. Researchers at the Helmholtz Zentrum München and the Technical University Munich have now presented a method in the journal "Allergy", which facilitates a personalised procedure.

Nanofiber scaffolds show new behaviour of stem and cancer cells


A discovery in the field of biomaterials may open new frontiers in stem and cancer cell manipulation and associated advanced therapy development. Novel scaffolds are shown enabling cells to behave in a different but controlled way in vitro due to the presence of aligned, self-assembled ceramic nanofibers of an ultra-high anisotropy ratio augmented into graphene shells.

Researchers has developed a computer model that will aid in the design of nanocarriers, microscopic structures used to guide drugs to their targets in the body. The model better accounts for how the surfaces of different types of cells undulate due to thermal fluctuations, informing features of the nanocarriers that will help them stick to cells long enough to deliver their payloads.
