The research interest of Mariacristina Missale has been primarily focussed on dopamine receptor signalling and function in the central nervous system and the pituitary. In particular, she was involved in the study of D2 receptor signalling and plasticity and identified a NGF-mediated mechanism controlling D2 receptor expression. Her laboratory is currently interested in the interactions of dopamine receptors with other neurotransmitter receptors and transductional proteins and in the identification of molecular mechanisms of levodopa-induced dyskinesias in animal models of Parkinson‰Ûªs disease. Recently she gave original contributions to the identification and characterization of dopamine receptor heterodimers and determined the role of these complexes in the development of levodopa-induced dyskinesias.
