Methods and products for identifying individuals who are likely to respond in a positive (benefit) or negative (harm) manner to a pharmacological drug treatment intended for treating or preventing a neuropsychiatric disorder, neurodegeneration, sleep-wake cycles such including and not limited to Alzheimer's disease, schizophrenia, autism and attention deficit disorders based on single nucleotide polymorphisms (SNP) chromosome 2, 2:107,510,000-107,540,000 locus (as disclosed in the Genome Reference Consortium Human genome build 37 (GRCh37)).

The present invention relates to: A schizophrenia animal model wherein the model is a mouse in which an anoctamin 1 (ANO1) gene is knocked out in cholinergic neurons of a medial habenula; and a preparation method therefor and the like. The schizophrenia animal model according to the present invention targets the medial habenula which is brain tissue playing a major role in the pathogenesis of schizophrenia, and it has been confirmed that when the ANO1 gene is specifically knocked out in the cholinergic neurons of the medial habenula, positive, negative and cognitive symptoms of schizophrenia are observed, thereby confirming that schizophrenia has been induced. Therefore, the animal model of the present invention is expected to be effectively useful in schizophrenia pathogenesis research and therapeutic agent development and screening.

The present invention provides combinations of biomarkers that can be used in the diagnosis and differentiation of bipolar disorder and schizophrenia. The present invention therefore provides methods of differentiating, diagnosing and treating bipolar disorder and schizophrenia, by examining relevant proteins and RNA in a patient sample.

The present invention relates to a biomarker composition for predicting the prognosis of brain diseases caused by microplastic exposure and a use thereof, wherein it was confirmed that polyethylene microspheres (PS) in a mouse animal model orally administered with the PS penetrate brain tissue to change the level of gene expression inside the brain tissue, thereby causing brain diseases, and thus the present invention is intended to provide: a biomarker composition for predicting the prognosis of brain diseases caused by microplastic exposure, the biomarker composition using a gene in which the expression level in an individual suspected of exposure to PS is identified; and a method for predicting the prognosis of brain diseases using the biomarker composition.

The present invention provides a method of screening a mammal for the onset or predisposition to the onset of a neuropsychiatric disorder. More particularly, the present invention provides a method of screening a mammal for the onset or predisposition to the onset of schizophrenia by screening for a decrease in the functional level of protein 1 4-3-3ξ. In a related aspect, the present invention also provides a means of monitoring a patient diagnosed with a neuropsychiatric disorder, such as schizophrenia, by screening for changes to functional levels of protein 14-3-3 ξ. This may be useful, for example, in the context of evaluating the effectiveness of a prophylactic or therapeutic treatment regime or otherwise monitoring the impact of physiological or metabolic changes which may occur in a patient. The method of the present invention is useful in a wide range of applications including, inter alia, providing a means of identifying mammals susceptible to the onset of a neuropsychiatric condition, such as a condition characterized by one or more symptoms of schizophrenia, thereby enabling the implementation of prophylactic or early therapeutic intervention in an effort to either minimize or prevent the onset of the condition. It also provides a means of confirming diagnoses which would otherwise be based solely on an assessment of positive and negative symptoms.

Provided is a composition including a combination of at least one short peptide and at least one peptide dimer, in defined ratio, to which autoantibodies found in elevated levels in schizophrenic patients bind.

The present invention provides a method of screening a mammal for the onset or predisposition to the onset of a neuropsychiatric disorder. More particularly, the present invention provides a method of screening a mammal for the onset or predisposition to the onset of schizophrenia by screening for a decrease in the functional level of protein 14-3-3ζ. In a related aspect, the present invention also provides a means of monitoring a patient diagnosed with a neuropsychiatric disorder, such as schizophrenia, by screening for changes to functional levels of protein 14-3-3ζ.

Disclosed is an antibody which binds to aripiprazole, which can be used to detect aripiprazole in a sample such as in a competitive immunoassay method. The antibody can be used in a lateral flow assay device for point-of-care detection of aripiprazole, including multiplex detection of aripiprazole, olanzapine, quetiapine, and risperidone in a single lateral flow assay device.

The present invention provides, inter alia, methods for treating or ameliorating the effects of a disorder, such as schizophrenia or bipolar disorder, by increasing or decreasing proline levels. Further provided are methods of predicting and monitoring the clinical response in a patient, and diagnostic systems for identifying a patient likely to benefit from proline modulation.
