SUMMARY

Abnormality of dopamine D2 receptor (D2R) function, often characterized as D2R supersensitivity (D2RSS), is a commonality of schizopsychiatric disorders in humans. Moreover, virtually all psychotherapeutic agents commonly used for treatment of schizophrenia target, directly or  partially, D2R in brain. The series of topics in this symposium demonstrate an ability to: (1) produce an animal-model of D2RSS - from early ontogeny, mid-stage ontogeny, or late ontogeny; (2) demonstrate signaling processes associated with D2RSS; (3) present functional links between the biologic template of the animal models with overt measurable features of schizophrenia (i.e., BDNF, RGS9, etc.) – neurotoxicological effects in the absence of overt anatomical evidence of neuronal damage; and (4) illustrate the comparable effects of pharmacotherapeutics in modulating biologic and behavioral modalities towards ‘normalcy’ in the animal model versus individuals beset with schizophrenia. A new animal model of schizophrenia, to be presented, has face validity, construct validity and predictive validity with schizophrenia; and imparts several distinct advantages over earlier models, with the impression of being more predictive of pharmacotherapic efficacy.
