2.Introduction of Research

Department of Neuropsychopharmacology
 The brain controls all body activities, ranging from heart rate to memory. Each brain function is operated by particular neural circuits made by synapses. The most important feature of synapses is the activity-dependent plasticity. The long-term objective in our laboratory is twofold. One is to define the molecular and cellular mechanisms that regulate synaptic plasticity associated with learning and memory. In particular, we are interested in molecular and cellular mechanisms that are responsible for working/short-term memory and reference/long-term memory. The other is to define the pathogenesis/pathophysiology of neuropsychiatric brain disorders, including Alzheimer’s disease, schizophrenia and drug addiction. Our current efforts have been focused on the following projects.


(1)Schizophrenia and other mental disorders
 Both genetic and environmental factors play a role in the pathology of schizophrenia. Recently, genetic susceptibility factors for the disorder have become available, which include neuregulin-1, dysbindin, and disrupted-in-schizophrenia 1 (DISC1). Epidemiological studies have identified environmental factors for schizophrenia, and maternal viral infection during pregnancy is regarded as the most promising one. Viral infection in the second trimester of pregnancy in humans increases the risk of subsequently developing schizophrenia in adolescence/adulthood. A possible interaction between environmental and genetic susceptibility factors, especially during neurodevelopment, is proposed for the disease etiology.
 We focus on phenotypic analyses at behavioral, neurochemical and neuroanatomical levels in mice with mutant schizophrenia susceptibility genes such as DISC1. We also study a possible interaction of genetic and environmental factors in schizophrenia by using a genetically-engineered mouse models under exposure to the synthetic double strand RNA polyriboinosinic-polyribocytidilic acid [polyI:C, a toll-like receptor 3 (TLR3) ligand that induces strong innate immune response]. PolyI:C has been used to mimic a viral infection during neurodevelopment for modeling schizophrenia in mice.


(2)Alzheimer’s disease and other neurodegenerative disorders
 Alzheimer’s disease (AD) is a progressive neurodegenerative process characterized by senile plaques, neurofibrillary tangles and neuronal loss. A pathologic hallmark of AD is deposition of amyloid-? peptide (A?), a 39-43-amino acid peptide derived from the transmembrane amyloid precursor protein (APP). Fibrillar A? deposits are found in extracellular senile plaque cores and are associated with neurodegeneration in later stages of AD. We study the mechanisms underlying the A?-induced neurotoxicity in vivo, by directly injecting A? into the lateral ventricle. We have already discoverd novel compounds to prevent the A?-induced neurotoxicity.


(3)Drug addiction/dependence
 Drug addiction/dependence is defined as a chronically relapsing disorder that is characterized by compulsive drug taking, inability to limit intake, and intense drug cravings. The positive reinforcing/rewarding effects of drugs primarily depend on the mesocorticolimbic dopamine system innervating the nucleus accumbens while the craving for drugs is associated with activation of the prefrontal cortex. The chronic intake of drugs causes homeostatic molecular and functional changes in synapses, which may be critically associated with the development of drug dependence. We have demonstrated that various cytokines such as TNF-? and GDNF and proteinases such as tissue plasminogen activator (tPA) and matrix metalloproteinase (MMP-2/MMP-9) are produced in the brain on treatment with drugs of abuse, and play a role in drug dependence. These endogenous modulators of drug dependence are classified into two groups, pro-addictive and anti-addictive factors. We have proposed that an imbalance between pro-addictive and anti-addictive factors contributes to the development and relapse of drug dependence. Targeting these endogenous modulators would provide new therapeutic approaches to the treatment of drug dependence.  


(4)Basic mechanisms of learning/memory and emotion
 Recognition memory is a fundamental facet of ability to remember, and an integral component of the class of memory lost in amnesia. The ability to discriminate familiar from novel stimuli is supported by this form of memory and is widely used as an assay in animals. Recent work highlights a major role in recognition memory for the perirhinal cortex because lesions or transient inactivation of perirhinal cortex consistently disrupt performance on familiarity discrimination tasks with object in both primates and rats.


 We have previously demonstrated that the activation of ERK1/2 following stimulation of dopamine D1 receptors in the prefrontal cortex is necessary for the protein synthesis-dependent long-term retention of recognition memory. Now, we focus on the possible interaction between dopamine and glutamate systems in protein synthesis-dependent long-term retention of recognition memory. Furthermore, we look for target genes of the dopamine D1 receptor-ERK1/2 signaling which are responsible for long-term recognition memory.


Department of Hospital Pharmacy
 We conduct clinical researches in collaboration with clinical departments at Nagoya University Hospital. These studies include the effect of pharmaceutical care by pharmacists on patient’s QOL, pharmacokinetics of immunesuppressants, pharmacotherapy and side effects, and pharmacogenetics.
