Food can affect a cell in the same way hormones do
Date:12/7/2008

Leuven, Belgium VIB researchers connected to the Katholieke Universiteit Leuven have discovered an important new mechanism with which cells can detect nutrients. This happens in the same way − and with the same effects as when cells receive a message from a hormone. This finding can teach us more about how food affects our body; and, furthermore, it can form the basis for new candidate targets for medicines.

Receptors

Every living thing is composed of cells − and, via receptor proteins on their outer surface, cells communicate with each other and with the outside world. Receptors are found on skin cells (pain and pressure receptors, for example) as well as on the cells of other tissues and organs. By binding with certain substances, such as hormones, the receptors pick up signals from outside the cell. They transmit the signal to the interior of the cell, where it can induce all kinds of reactions. Receptors can be stimulated or blocked to evoke or prevent a certain effect. Foreign substances, such as medicines, can also bind to a receptor and cause a particular effect. For some time now, scientists have suspected that cells can also detect the presence of food via one or another receptor − but no one has known how that happens.

Sensing and transporting

In addition to receptors, cells also have transport proteins that can carry nutrients through the cell membrane to the inside of the cell, where they can be put to use. Furthermore so-called 'transceptors' have been discovered that sense and transport food simultaneously.

Now, VIB researcher Griet Van Zeebroeck and her colleagues in Johan Thevelein's group have shown for the first time how one of these transceptors (called Gap1) works. Gap1 transports amino acids (a protein's building blocks) to the inside of a cell. At the same time, via the same mechanisms that cells use to transmit signals from hormones, Gap1 sends the cell a signal
