Signal transduction without signal: Receptor clusters can direct cell movement

Signal transduction without signal: Receptor clusters can direct cell movement
Whether we smell, taste or see, or when adrenaline rushes through our veins, all of these signals are received by our cells via a specific group of receptor proteins called G protein-coupled receptors, which transmit signals to the inside of the cell. Biochemists have now discovered that such...

Damage to the heart found in more than half of COVID-19 patients discharged from hospital

Damage to the heart found in more than half of COVID-19 patients discharged from hospital
Around 50 percent of patients who have been hospitalized with severe COVID-19 and who show raised levels of a protein called troponin have damage to their hearts. The injury was detected by magnetic resonance imaging (MRI) scans at least a month after discharge, according to new findings. source...
