Central Muscarinic Receptors as Novel Drug Targets for Parkinson's Disease and Schizophrenia. Psychiatric and neurodegenerative disorders such as schizophrenia and Parkinson's disease are linked to alterations in the activity of neurons in the brain containing the chemical dopamine. Other types of brain neurons containing the chemical acetylcholine regulate dopamine neuron activity by acting on acetylcholine receptors located on dopamine neurons. We aim to determine how these important recepto ....Central Muscarinic Receptors as Novel Drug Targets for Parkinson's Disease and Schizophrenia. Psychiatric and neurodegenerative disorders such as schizophrenia and Parkinson's disease are linked to alterations in the activity of neurons in the brain containing the chemical dopamine. Other types of brain neurons containing the chemical acetylcholine regulate dopamine neuron activity by acting on acetylcholine receptors located on dopamine neurons. We aim to determine how these important receptors regulate dopamine neuron activity using genetically modified mice deficient in acetylcholine receptors, together with newly developed physiological methods and new acetylcholine receptor drugs. These studies will foster the design of novel acetylcholine receptor drugs as effective pharmaceutical treatments of neurological and psychiatric disorders related to brain dopamine dysfunction.Read moreRead less
Muscarinic Receptor Regulation of Dopamine Reward Pathways in the Brain. Human disorders such as schizophrenia and drug addiction are linked to alterations in the activity of neurons in the brain containing the chemical dopamine. Other types of brain neurons containing the chemical acetylcholine regulate the activity of dopamine neurons by acting on acetylcholine receptors located on dopamine neurons. We aim to examine how dopamine neuron activity is regulated by these receptors using newly de ....Muscarinic Receptor Regulation of Dopamine Reward Pathways in the Brain. Human disorders such as schizophrenia and drug addiction are linked to alterations in the activity of neurons in the brain containing the chemical dopamine. Other types of brain neurons containing the chemical acetylcholine regulate the activity of dopamine neurons by acting on acetylcholine receptors located on dopamine neurons. We aim to examine how dopamine neuron activity is regulated by these receptors using newly developed physiological methods together with a new acetylcholine receptor drug. We also aim to assess the suitability of mice genetically modified to be deficient in acetylcholine receptors as animal models of dopamine dysfunction related to schizophrenia and drug addiction.Read moreRead less
