After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

Neurotoxoplasmosis, brain abscess caused by parasitic protozoan Toxoplasma gondii and close-up view of Toxoplasma gondii in bradyzoite stage, computer illustration. T. gondii is a species of parasitic protozoa that can be carried by all known mammals. It causes toxoplasmosis, a usually minor and self-limiting disease. It can, however, have serious or even fatal effects on an unborn foetus if the mother contracts toxoplasmosis during pregnancy. Also, it can cause abscesses of inner organs and brain in immunocompromised patients, such as in HIV-infected patients.
