Researchers at IRB Barcelona discover the mechanism that leads to a less harmful form of obesity that is associated with the number rather than volume of fat cells.

There are several types of obesity and some are more harmful than others.

The study has been published in the journal Nature Cell Biology.

A study headed by IRB Barcelona provides the first direct evidence of beta-amyloid dimers (two proteins joined together) in patients with Alzheimer’s disease and points to the potential of these molecules as biomarkers.

Beta-amyloid dimers may be the smallest pathological species that trigger Alzheimer’s disease.

The new study analyses the dysfunction of basolateral transporters through a transgenic animal model.

This study is led by Manuel Palacín from IRB Barcelona and Virgínia Nunes from IDIBELL.

It seems the amino acid transporter SLC7A8/SLC3A2 plays an important role in this disease.

The study was coordinated by Manuel Palacín from IRB Barcelona and Virginia Nunes from IDIBELL.

In spite of the difference between the cell functions responsible for giving rise to a tumour and for the metastasis of this same tumour, studies at IRB Barcelona using the fly Drosophila melanogaster reveal that some genes can drive both phenomena.

A team headed by ICREA researcher Eduard Batlle discovers that immune system-stimulating treatments combined with a TGF-beta inhibitor are effective against colon cancer.

The researchers developed a mouse model that mimics advanced human colon cancer. This model has allowed them to study the immune system response for the first time.
