Discovery of a Novel Cell Adhesion Mechanism

In a process essential to the immune system’s response to infection, dendritic cells responsible for identifying pathogens communicate with the T-cells that destroy the infectious agents.

To achieve this, the dendritic cells must be correctly activated and migrate to the lymph nodes where they must adhere firmly to T-cells.

Novel Evolutionary Theory for the Explosion of Life

The Cambrian Explosion is widely regarded as one of the most relevant episodes in the history of life on Earth, when the vast majority of animal phyla first appear in the fossil record.

However, the causes of its origin have been object of debate for decades and the question of what was the trigger for the single cell microorganisms Precambrian Age (500 Mio. Years ago) to assemble and organize into multicellular organisms (Metazoans) has remained unanswered until now.

Feeling and pressing the cytoplasm

IBEC researcher in collaboration with a Harvard-led team in PNAS

Imagine an opaque bag in front of you and you wish to figure out what’s inside, what would you do? You can’t open it. So you press and you feel the content, then you might be able to tell whether it is a bag of glass beads or soft balls.

New Light Technique Developed to Observe Real-Time Cellular Activity on a Nanometric Scale

In any biological process, multiple interactions occurring at the molecular level make it impossible to observe live cells in real time, because light microscopes cannot focus light at scales of less than 350 nanometres. 

New breakthroughs in nanophotonics, however, will shortly enable us to visualise molecular processes at an optical resolution of ten nanometres, according to researcher María García-Parajo, head of the Bionanophotonics Laboratory at IBEC.

(Un nou descobriment sobre l’evolució del DNA)

Un equip internacional d’investigadors liderat per Eduard Torrents de l’Intitut de Bioenginyeria de Catalunya (IBEC), ubicat al Parc Científic de Barcelona, i Britt-Marie Sjöberg del Departament de Biologia Molecular i Genòmica Funcional de la Universitat d’Estocolm, en col·laboració amb científics de la Universitat de Western Ontario de Canadà, ha descobert com la síntesi d’algunes molècules precursores del DNA podria haver-se desenvolupat al llarg de l’evolució.

El treball, que s’ha publicat a l’edició electrònica de la revista Proceedings of the National Academy of Sciences (PNAS), es basa en l’estudi de l’enzim responsable de la síntesi d’aquestes molècules en un virus bacterià.
