We evaluated the practicability of using the rarely utilized C57BL/6N mouse as a Parkinson's disease model established via the acute MPTP/probenecid (MPTP/p) protocol. We confirmed dopaminergic degeneration in terms of decreased expression levels of tyrosine hydroxylase in the substantia nigra and striatum of MPTP/p-lesioned mice. In addition, acute MPTP/p-lesioned mice demonstrated initial motor dysfunctions followed by spontaneous recovery. Interestingly, these MPTP/p-lesioned mice exhibited anxiolytic and antidepressive behaviors upon recovery from these motor deficits. Additionally, increased expression of norepinephrine transporters in several brain regions, including the hippocampus, medial prefrontal cortex, and striatum, and an elevated rate of adult neurogenesis (in terms of increased numbers of doublecortin-positive neuroblasts) in the hippocampus were observed after recovery from motor dysfunctions. We suggest that the emotional alterations observed under these experimental conditions may be associated with enhanced adult neurogenesis, increased levels of norepinephrine transporters, and/or a possible interplay between these two factors. Consequently, this acute MPTP/p model adequately satisfies the criteria for the validity of a Parkinson's disease model regarding dopaminergic loss and motor impairment. However, the non-motor findings may offer novel evidence against the practicability of utilizing the acute MPTP/p-lesioned mice for modeling the emotional aberrations found in Parkinson's disease patients.

Introduction: Neuroinflammation is correlated to neurodegenerative diseases like Alzheimer's disease (AD), Amyotrophic Lateral Sclerosis (ALS), Multiple Sclerosis (MS), Huntington Disease (HD) and Parkinson's disease (PD). A lot of recent research and patents are focused on the design and synthesis of arachidonic acid Lipoxygenase (ALOX) inhibitors for the treatment of neurodegenerative diseases.
Areas Covered: The survey covers natural products, synthesis, hybrids, and assessments of biological effects in biological studies as ALOX inhibitors.

Parkinson's disease (PD) is a common neurodegenerative disease affecting nearly 10 million people worldwide and placing a heavy medical burden on both society and families. However, due to the complexity of its pathological mechanisms, current treatments for PD can only alleviate patients' symptoms. Therefore, novel therapeutic strategies are urgently sought in clinical practice.

Continuous subcutaneous infusion of foslevodopa/foscarbidopa (LDP/CDP) may be effective in improving daytime symptoms in patients with Parkinson's disease (PD). We report on a PD patient for whom LDP/CDP treatment improved motor symptoms, sleep disturbances and sleep architecture as measured by the mobile two-channel electroencephalography/electrooculography recording system.
