El músculo liso es un tejido que se encuentra generalmente recubriendo órganos (músculo liso visceral: tubo digestivo, colon, próstata, etc.) y vasos sanguíneos (músculo liso vascular: venas y arterias), aunque también puede hallarse aisladamente (músculo eréctil del vello). Las células musculares lisas son alargadas, con forma fusiforme, y su...

The optic lobes of the fruit fly Drosophila melanogaster form a highly wired neural network composed of roughly 130.000 neurons of more than 80 different types. How neuronal diversity arises from very few cell progenitors is a central question in developmental neurobiology. We use the optic lobe of the fruit fly as a paradigm to understand how...

Voltage-gated Ca2_ channels in arterial myocytes can mediate Ca2_ release from the sarcoplasmic reticulum and, thus, induce contraction without the need of extracellular Ca2_ influx. This metabotropic action of Ca2_ channels (denoted as calcium-channelinduced calcium release or CCICR) involves activation of G proteins and the phospholipase...
