CNIC scientists discover a cell behavior pattern that predicts
cardiovascular disease
Scientists led by Dr. Andrés Hidalgo at the CNIC have discovered
that circulating neutrophils acquire different behavior patterns during inflammatory
processes. The study, published in Nature, identifies a harmful neutrophil behavior
associated with cardiovascular disease.

CNIC scientists identify a shuttle protein required for the nuclear
import of proteins essential for organ growth and development
Organ growth and regeneration require the entry into the cell
nucleus of proteins that activate essential genes for these processes. This process is the
subject of a new study by CNIC scientists, led by Dr. Miguel Ángel del Pozo, who heads the
Mechanoadaptation and Caveolae Biology group, and group member Dr. Asier Echarri. The
scientists have identified the mechanism that controls the nuclear import of these proteins
in response to mechanical stimuli, such as the hemodynamic forces generated by arterial
blood flow, tumor rigidity, or locomotory movements during routine activities like walking
or sports.

3D matrix ultrasound accurately identifies cardiovascular injury in
healthy individuals
A new imaging technique for real 3D vascular ultrasound could become
a key tool in strategies aimed at preventing cardiovascular disease in apparently healthy
persons, complementing traditional risk parameters such as cholesterol and high blood
pressure. The new results, published in JACC: Cardiovascular Imaging, show that real 3D
vascular ultrasound is reliable, accurate, and faster than previous methods for the
assessment of plaque volume in the carotid and femoral arteries.

Bone marrow contributes to the development of atherosclerosis
The activation of the bone marrow appears to play a key role in the
origin and development of atherosclerosis, the pathological process underlying
cardiovascular conditions such as myocardial infarction and stroke. A study carried out by
scientists at the CNIC and led by cardiologists Drs. Valentín Fuster and Borja Ibáñez
suggests that the bone marrow is activated in response to known cardiovascular risk factors.
In the study, published in the European Heart Journal, the researchers show that these risk
factors lead to an increase in the number of circulating inflammatory cells, which go on to
trigger the initiation and subsequent progression of atherosclerotic disease.

CNIC scientists uncover opposing roles of p38 proteins in cardiac
hypertrophy
A study carried out by scientists at the Centro Nacional de
Investigaciones Cardiovasculares (CNIC) and led by Dr. Guadalupe Sabio has identified a key
role for the MKK3/6–p38γ/δ signaling pathway in the development of cardiac hypertrophy. The
results, published in the journal eLife, suggest that inhibition of p38γ/δ could be a useful
therapeutic strategy for diseases such as hypertrophic cardiomyopathy; however, this avenue
remains unexplored because of the lack of specific inhibitors for these kinase enzymes. The
study also shows the opposite effect upon inhibition of another member of this protein
family, p38α, indicating that long-term clinical use of p38α inhibitors to treat chronic
disease risks damage to the heart.
