Impact of 5-Lipoxygenase Deficiency on Dopamine-Mediated Behavioral Responses.

The 5-lipoxygenase/leukotriene system has been implicated in both physiological and pathological states within the central nervous system. Understanding how this system interacts with the dopaminergic system could provide valuable insights into dopamine-related pathologies. This study focused on examining both motor and non-motor dopamine-related responses in 5-lipoxygenase/leukotriene-deficient mice.

Cannabidiol attenuates prepulse inhibition disruption by facilitating TRPV1 and 5-HT1A receptor-mediated neurotransmission.

Individuals with schizophrenia (SCZ) often present sensorimotor gating impairments that can be investigated by the prepulse inhibition test (PPI). PPI disruption can be mimicked experimentally with psychostimulants such as amphetamine and attenuated/reversed by antipsychotics. Cannabidiol (CBD), the main non-psychotomimetic component of the Cannabis sativa plant, produces antipsychotic-like effects in clinical and preclinical studies.

Nanotechnology in Improving the Treatment of Huntington's Disease: a Systematic Review.

Huntington's disease (HD) is a degenerative genetic condition characterized by cognitive, motor, and psychiatric disturbance. It is caused by a dominantly inherited alteration in the huntingtin gene. Even though symptomatic management is the mainstay of HD treatment, in the thesis, one of the leading causes of the low success of current therapy is their low efficacy for crossing the blood-brain barrier (BBB).

Upregulation of FosB/ΔFosB in limbic circuits after tooth exodontia-induced occlusal instability in an experimental model of unpredictable chronic stress.

Psychological stress and occlusal alterations are contributing etiologic factors for temporomandibular and muscular disorders in the orofacial area. The neural modulation recruited for this relationship, however, is not elucidated. The aim of this study was to investigate potential central mechanisms involved in the exodontia-induced occlusal instability associated with unpredictable chronic stress (UCS).

Effects of JL13, a pyridobenzoxazepine compound, in dopaminergic and glutamatergic models of antipsychotic activity.

The pyridobenzoxazepine compound, 5-(4-methylpiperazin-1-yl)-8-chloro-pyrido[2,3-b][1,5]benzoxazepine (JL13), has been developed as a potential antipsychotic drug. We tested the hypothesis that JL13 is efficacious in both dopaminergic and glutamatergic animal models of schizophrenia. We investigated JL13 for its efficacy to prevent cocaine- and ketamine-induced hyperlocomotion and MK-801-induced deficits in prepulse inhibition (PPI) of the startle reflex.
