Special Issue Information

Dear Colleagues,

Parkinson’s disease (PD) is multifactorial age-related brain disease characterized by bradykinesia, fatigue, irregular blood pressure and major muscle-stiffness-associated difficulties. Despite extensive research, there is no cure for PD. To make scientific advances regarding therapeutic discoveries and mechanistic approaches to determining the basis of PD progression, PD modeling is a critical step. Currently, available cellular and genetic rodent models remain inefficient. For example, iPSC-based disease modeling and iPSC (induced pluripotent stem cell)-derived neurons (iNs) are not mature enough to recapitulate age-related pathological events, which instead require tools that can accelerate iNs maturation. In a different study, a disease-causing agent extracted from the human brain, supplemented with an in vitro growth media to induce PD pathogenesis, was proven to be a powerful approach to studying pathogen-specific disease induction, which is rapid and pathogen-species-specific; however, it does not eventually mimic the progressive manner of disease. Inducible and genetic rodent models also have pathological characteristics. We strive to improve model systems to allow us to identify cellular mechanisms underpin the development, onset, progression, and end stages of the disease, which are critical for finding successful treatments.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Biomedicines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Researchers are actively exploring potential bioactive compounds to enhance the effectiveness of Lisuride (Lis) in treating Parkinson’s disease (PD) over the long term, aiming to mitigate the serious side effects associated with its extended use. A recent study found that combining the dietary flavonoid Tiliroside (Til) with Lis has potential anti-Parkinson’s benefits. The study showed significant improvements in PD symptoms induced by 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) when Til and Lis were given together, based on various behavioral tests. This combined treatment significantly improved motor function and protected dopaminergic neurons in rats with PD induced by MPTP. It also activated important molecular pathways related to cell survival and apoptosis control, as indicated by the increased pAkt/Akt ratio. Til and Lis together increased B-cell lymphoma 2 (Bcl-2), decreased caspase 3 activity, and prevented brain cell decay. Co-administration also reduced tumor necrosis factor alpha (TNF-α) and Interleukin-1 (IL-1). Antioxidant markers such as superoxide dismutase (SOD), catalase, and reduced glutathione significantly improved compared to the MPTP-induced control group. This study shows that using Til and Lis together effectively treats MPTP-induced PD in rats, yielding results comparable to an 8 mg/kg dose of levodopa, highlighting their potential as promising Parkinson’s treatments.
