This results in a harmful build-up of fat molecules in the brain and other organs.

"MiRNAs are small RNA molecules that do not encode proteins like most genes do, yet they play essential roles in gene regulation by repressing the expression of target genes," added Dr Tian.

The pyruvate enters the cells of the body, and the scan shows the rate at which it is broken down -- or metabolised -- into a molecule called lactate.

Their modeling suggests that two molecules of nerve growth factor, two molecules of TrkA, and two molecules of NRP1 together form a pain signaling complex.

While numerous sensors exist to continuously detect small molecules, such as glucose or electrolytes, sensors for proteins -- which are larger and more complex than small molecules -- are more challenging to design.
