Vicious circle leads to loss of brain cells in old age

The CB1 receptor is responsible for the intoxicating effect of cannabis. However, it appears to act also as a kind of ‘sensor’ with which neurons measure and control the activity of certain immune cells in the brain. A recent study at least points in this direction. If the sensor fails, chronic inflammation may result — probably the beginning of a dangerous vicious circle.
