A new technique allows researchers to focus the action of drugs via infrared light

A scientific team led by IBEC and UAB manages to efficiently activate molecules located inside cell tissues using two-photon excitation of with infrared light lasers. The results of the study has been published in Nature Communications.

Having absolute control of the activity of a molecule in an organism. Deciding when, where and how a drug is activated. These are some of the goals expected to be reached with the so-called photoswitchable molecules, compounds that, in the presence of certain light waves, change their properties. Today, thanks to the results of a study led by the Institute for Bioengineering of Catalonia (IBEC) together with the Universitat Autònoma de Barcelona (UAB), the scientific community is one step closer to achieving this objective.

Proteins can transfer electrons at a distance

Collaborating IBEC groups have published a study in Nature Communications that reveals that electron transfer can take place while a protein is approaching its partner site, and not only when the proteins are engaged, as was previously thought.

The results open up a new way of thinking about how proteins interact, and can have implications in a better understanding of many processes – such as photosynthesis, respiration and detoxification – in which electron transfer plays an important role.

The relocation of an electron from one chemical entity to another – electron transfer (ET) – doesn’t happen passively: electrons are carried individually by redox proteins.

IBEC researchers uncover strategy to reduce chemotherapy side effects

Researchers at IBEC and IDIBELL have developed a light-regulated molecule that could improve chemotherapy treatments by controlling the activity of anticancer agents.

Chemotherapy – the use of cytotoxic agents to kill the rapidly proliferating cells in tumors – is one of our main tools in the fight against cancer. However, its effectiveness and the body’s tolerance of it is often dramatically limited: it can affect healthy areas rather than just the cancerous ones, which causes side effects.

“Estrategias optogenéticas y fotofarmacológicas para restablecer la visión”

The latest edition of Visión, the magazine of the Federación de Asociaciones de Retinosis Pigmentaria de España (FARPE), features an article by IBEC’s Pablo Calvé and Pau Gorostiza.

Molecules activated by light to control glutamate receptors

Researchers at IBEC, IQAC-CSIC and CNRS have developed molecules that can modulate the activity of glutamate receptors in the central nervous system, with important applications in biomedicine.

For the last few years the collaborators have been working on the development of molecules called targeted covalent photoswitches (TCPs), whose structure can be changed using light. This change in shape causes the molecule to be recognized – or not – by a biological receptor as a key is to a lock. This coupling activates the receptor or not, triggering the activity.

Celebrating advances in spinal cord and brain research by Marató-funded projects

IBEC group leader and ICREA research professor Pau Gorostiza took part in the 17th Symposium of La Marató de TV3 this week, which was devoted to the celebration of the 30 research projects awarded funding by the telethon in 2010.

The event at the Institut d’Estudis Catalans on Wednesday, which included a poster session open to the public, featured round tables of experts discussing the findings of the projects, which covered research into the understanding, treatment and prognosis acquired spinal cord and brain injuries.
