Begin quote There are also dopamine receptors on the surface of white blood cells called lymphocytes.
The research team compared the number on the blood cells of diagnosed schizophrenics with the number on the blood cells of healthy individuals.
Even checking the number of these receptors on blood cells is extremely difficult, however, and the team, from the Weizmann Institute in Israel, found a way of testing the levels of molecules which control the formation of the receptors.
A statistical analysis showed that the blood of patients with schizophrenia on average contained 3.6 times more of these molecules, called D3 messenger RNA molecules, than the blood of healthy people.
