Researchers at IBEC reveal in a Nature Communications paper some surprising mechanics that drive epithelial gap closure in the absence of underlying layers

In a collaboration with their colleagues at the Mechanobiology Institute in Singapore, IBEC researchers have demonstrated that a kind of ‘tug-of-war’ takes place after our skin or other epithelial layer is damaged, particularly in cases where the tissue is chronicly or deeply injured.

Researchers in Barcelona discover more potential candidates on the route to tailored, photo-switchable therapies by disproving design limitation

Last year, scientists at the Institute for Bioengineering of Catalonia (IBEC), IRB Barcelona and the UB announced that they had achieved photo-switchable, or light-regulated, molecules to control protein-protein interactions – key determinants in biological processes, and therefore highly promising therapeutic targets – in a remote and non-invasive way.

A group at IBEC has identified a important factor in E. coli infection, opening the way to developing targeted drugs against the potentially deadly condition.

Most E. coli bacterial strains occur naturally in the human gut and pose no harm to health, except for the one particular serotype that always hits the news, O157:H7, which can cause food poisoning and can become life-threatening in certain patients.

Even though lower back pain and spinal disorders are the leading cause of disability in western countries, their treatment still leaves a lot to be desired.

We all know how emotive smells can be; just the mere whiff of candy floss or plasticine can transport you back decades in a moment.

But how does our olfactory system recognise odours even at very low doses?

Two groups working together at IBEC demonstrate the potential of electrical studies of single bacterial cells in a paper published in ACS Nano.

Gabriel Gomila’s Nanoscale Bioelectrical Characterization group and that of Antonio Juárez, Microbial Biotechnology and Host-pathogen Interaction, combined their expertise on microscopic electrical measurements and bacteria respectively to come up with a way to study the response to external electrical fields of just a single bacterial cell.

Researchers in IBEC’s Nanoprobes and Nanoswitches group and their collaborators have announced the development of the first ever light-controlled therapeutic agent whose effects focus specifically on the largest, most important class of drug target proteins – G protein-coupled receptors.

In the journal Nature Chemical Biology this week, the scientists reveal Alloswitch-1, the latest advance in their research into photoswitchable (or light-operated) drugs. Controlling drug activity with light means that the therapeutic effects can be accurately delivered locally, thus reducing their effect on other areas and the resultant side effects, and helps reduce the dosage required.

The electric polarizability of DNA is a fundamental property that directly influences its biological functions. Despite the importance of this property, however, its measurement has remained elusive so far.

In a study published in PNAS today, researchers at Barcelona’s Institute for Bioengineering of Catalonia (IBEC) led by Laura Fumagalli, senior researcher at IBEC and lecturer at the University of Barcelona, and their collaborators at the Institute for Research in Biomedicine (IRB) and at Barcelona Supercomputing Center (BSC), and at Centro Nacional de Biotecnologia (CNB-CSIC) and IMDEA Nanociencia in Madrid, describe how they have found a way to directly measure DNA electric polarizability – represented by its dielectric constant, which indicates how a material reacts to an applied electric field – for the first time ever.

When we think of wound healing, we normally think of wounds to our skin. But wounds happen inside the body in all sorts of tissues and organs, and can have implications in many chronic diseases such as diabetes and asthma. Wounds also favour cancer progression by providing a physical and chemical environment that promotes the invasion of malignant cells.

Now, a group at the Institute for Bioengineering of Catalonia (IBEC) has found a new way to decipher the mechanisms of wound healing, and by doing so has uncovered a new understanding of how cells move and work together to close a gap in a tissue.

Research carried out at IBEC has opened the way to new applications to control the activation of neurons and other working parts of cells.

The dream of precisely and remotely controlling every aspect of the cell’s inner workings in tissue offers the promise of uncovering the molecular mechanisms of complex cellular processes, which in turn can lead to leaps in our understanding of what happens when things go wrong – for example, how and when neurodegenerative diseases can develop.
