Uncoupling DISC1 × D2R Protein-Protein Interactions Facilitates Latent Inhibition in Disc1-L100P Animal Model of Schizophrenia and Enhances Synaptic Plasticity via D2 Receptors.

Both Disrupted-In-Schizophrenia-1 (DISC1) and dopamine receptors D2R have significant contributions to the pathogenesis of schizophrenia. Our previous study demonstrated that DISC1 binds to D2R and such protein-protein interaction is enhanced in patients with schizophrenia and Disc1-L100P mouse model of schizophrenia (Su et al., 2014).

Allele-Specific Biased Expression of the CNTN6 Gene in iPS Cell-Derived Neurons from a Patient with Intellectual Disability and 3p26.3 Microduplication Involving the CNTN6 Gene.

Copy number variations (CNVs) of the human CNTN6 gene caused by megabase-scale microdeletions or microduplications in the 3p26.3 region are often the cause of neurodevelopmental disorders, including intellectual disability and developmental delay. Surprisingly, patients with different copy numbers of this gene display notable overlapping of neuropsychiatric symptoms.

Age-specific peculiarities of formation of long-term posttetanic potentiation in OXYS rats.

OXYS rats with hereditary hyperproduction of active oxidative radicals and early disorders in the mitochondrial structure and functions are an interesting model for studies of age-specific features of synaptic plasticity. The formation of long-term posttetanic potentiation in the mossy fibers-CA3 pyramidal neuron system were studied in hippocampal slices from Wistar and OXYS rats aged 3 and 4.5 months (young), 11 (middle-aged), and 18 months (old).

Participation of L-type voltage-gated calcium channels in facilitation of long-term potentiation during the formation of morphine dependence in rats.

Parameters of long-term potentiation in the system mossy fibers-CA3 pyramidal neurons in hippocampal slices in experimental animals vary during the formation of chronic opiate dependence. During the first day of morphine treatment, the value of potentiation was significantly lower than in controls. Starting from day 8 and at early stages of dependence (days 25-29), facilitation of long-term potentiation was recorded.
