The way information travels inside the cells of our bodies is not unlike the wiring inside a computer chip, according to a new study that has unveiled the intricate workings of a network of calcium ions as intracellular messengers.
According to researchers from the University of Edinburgh in the UK, this “cell-wide web” uses a microscopic network of guides to transmit information across nanoscale distances and carry activities and instructions for the cells to perform — such as relaxing or contracting muscles, for example.
Calcium ions (Ca2+) are a fundamental part of the messaging system of our cells, and their signals are crucial for a wide variety of jobs, including cell growth, death, and movement. Now researchers have taken an unprecedented close look at just how calcium ions shuttle messages within the cell.
