Neurodegenerative disorders have a profound effect on the quality of life of patients and their environment. However, the development of adequate therapies requires accurate understanding of the underlying disease pathogenesis. On that account, yeast models can play an important role, as they enable the elucidation of the mechanisms leading to neurodegenerative disorders. Furthermore, by using so-called humanized yeast systems, the findings in yeast can be interpolated to humans. In this review, we will give an overview of the current body of knowledge on the use of yeast models with regard to Huntington's, Parkinson's and Alzheimer's disease. In addition to the results, obtained with the baker's yeast Saccharomyces cerevisiae, we also consider the existing literature on the less common but promising fission yeast Schizosaccharomyces pombe.

Epidemiological evidence has shown that the regular ingestion of vegetables and fruits is associated with reduced risk of developing chronic diseases. The introduction of the 3Rs (replacement, reduction, and refinement) principle into animal experiments has led to the use of valid, cost-effective, and efficient alternative and complementary invertebrate animal models which are simpler and lower in the phylogenetic hierarchy. Caenorhabditis elegans (C.

This study investigates the role of flavonoid Icaritin (ICT) in estrogen-deficient ovariectomized (OVX) female mice by activating the Estrogen receptor (ER)/ Phosphatidylinositol 3-kinase (PI3K)/Protein kinase B (Akt) signaling pathway, potentially delaying Parkinson's disease (PD) progression post-castration. Seventy-five 8-week-old C57BL/6J female mice underwent ovariectomy, followed by MPTP (20 mg/kg) injection for 7 days. ICT (20 mg/kg) was administered for 14 days, and motor function was assessed using various behavioral tests.

Traumatic brain injury (TBI) is identified as a risk factor for Parkinson's disease (PD), which is a neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra (SN). However, the precise mechanism by which chronic TBI initiates PD pathogenesis is not yet fully understood. In our present study, we assessed the chronic progression and pathogenesis of PD-like behavior at different intervals in TBI mice.

Alzheimer's disease (AD) is the leading cause of dementia in the elderly, clinically characterized by memory loss, cognitive decline, and behavioral disturbances. Its pathogenesis is not fully comprehended but involves intracellular depositions of amyloid beta peptide (Aβ) and neurofibrillary tangles of hyperphosphorylated tau. Currently, pharmacological interventions solely slow the progression of symptoms.

The foremost cause of dementia is Alzheimer's disease (AD). The vital pathological hallmarks of AD are amyloid beta (Aβ) peptide and hyperphosphorylated tau (p-tau) protein. The current animal models used in AD research do not precisely replicate disease pathophysiology, making it difficult for researchers to quickly and effectively gather data or screen potential therapy possibilities.
