Rosa studied Biochemistry at University of Oviedo and, after working for a while in immunology at the Center for Biological Research (CIB) and another brief period of systems biology at the Center for Genomic Regulation (CRG), she eventually got her PhD in systems neurobiology at the Max-Planck-Institute of Neurobiology in Munich. Her research deals with neuronal plasticity in mouse visual cortex and big 2-photon microscopes.

Hungry lonely brains

Hungry lonely brains

Neuroscience

By Rosa García-Verdugo

When hungry, not only our bodies long for food, our brains do too. And it appears that when it comes to social interaction, a similar thing happens. Social deprivation leads to a brain angry for social contact. A recent study [Livia Tomova et al (2020) Acute social isolation evokes midbrain craving responses similar to hunger […]

Gene editing could help reverse fast ageing in progeria

Gene editing could help reverse fast ageing in progeria

BiomedicineGenetics

By Rosa García-Verdugo

Gene editing could be the solution to progeria, a genetic disease, characterized by extremely fast ageing. Progeria causes fast ageing and premature death in people carrying a single-point mutation in the LMNA gene, which basically leads to the production of a toxic protein which slowly damages the cells, ageing the bodies. This simple misspelling of […]

Mitochondrial gene editing is now possible, thanks to a bacterium

Mitochondrial gene editing is now possible, thanks to a bacterium

Genetics

By Rosa García-Verdugo

Mitochondria are the energy-making machines in the cell. Also, since evolutionarily they are thought to evolve from symbiotic bacteria, they have their own little genomes, which are mainly evolved through the maternal side, and also maybe because of their important function, mutations in genes affecting them are very damaging, and even lethal. However, mitochondrial DNA […]

Parkinson’s disease is characterized by neuronal loss in the brain’s substantia nigra region. What if another cell type, namely, astrocytes, could replace them? The work of two research groups recently published Zhou, H. et al. Cell 181, 590–603.e16 (2020). shows that, at least in mice, transforming astrocytes (a non-neuronal cell type in the brain) into […]
