WebCaveolin-1 (cav-1) proteins participate in mechanotransduction and are required for the formation of a subset of extracellular vesicles (EVs) that participate in coronary artery disease. Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles) at its surface and inside. This texture is common in aphanitic, or glassy, igneous rocks that have come to the surface of the earth, a process known as extrusion. As magma rises to the surface the pressure on it decreases. When this happens gasses dissolved in the magma …
