A CNIC study extends the understanding of how acquired mutations in blood cells act as a new cardiovascular risk factor

Cells use two mechanisms to detect force: one gradual and progressive mediated by newly identified large membrane depressions called dolines (left); the other abrupt, activated above a certain threshold, and mediated by minute membrane invaginations called caveolae (right).

A study published in Nature Cell Biology confirms that caveolae are essential for the mechanical responses of tissues subject to large mechanical forces (such as muscle, heart, blood vessels, and fat), whereas larger membrane depressions (termed 'dolines') are important for the response to weak or medium-strength forces

A CNIC team has shown that the  retinoid and unsaturated fatty acid sensor RXR is a key protein in the maintenance of a balanced production of the different types of blood cells

Fibroblasto embrionario murino Cav1KO (izquierda, sin caveolas) muestra un mayor reclutamiento de integrina beta 1 activa (magenta) en torno a bolitas recubiertas con fibronectina, en comparación con un fibroblasto embrionario murino Cav1WT (derecha, con caveolas).

A new study published in eLife shows that small cups or nanofolds on the cell membrane called caveolae, by limiting abrupt changes in membrane tension, regulate the number and activity of mechanical microsensors on the cell surface called integrins

The results of the SPHERE-HF study are published in the European Journal of Heart Failure. SPHERE-HF is a multicenter academic clinical trial led by investigators at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) and Hospital Clínic de Barcelona

Transverse heart sections from wild type mice (WT) and transgenic mice overexpressing beta-3 adrenergic receptor in cardiomyocytes (c-h3tg) after 3 months of aortic stenosis (transaortic constriction, TAC) or control (sham). Hypertrophy after TAC was less severe in the transgenic mice
