Pharmacological actions of a novel and highly selective D3 dopamine receptor agonist, ML417, in a rodent model of Parkinson's disease.

FASEB J 2022 May;36 Suppl 1

Molecular Neuropharmacology Section, National Institute of Neurological Disorders and Stroke, NIH, Bethesda, MD.

Since its first use in treating Parkinson's disease (PD), L-DOPA has remained the gold standard of therapy for this disorder, defined by the progressive degeneration of dopaminergic neurons in the CNS leading to profound bradykinesia and tremor. The efficacy of L-DOPA wanes over time and is associated with increasing side effects, including motor fluctuations and dyskinesias. Several dopaminergic agonists have also been introduced to treat PD, including pramipexole and ropinirole, which exhibit fewer motor side effects but are associated with impulse control disorders such as excessive gambling and hypersexuality.

Progresses and Prospects of Neuroprotective Agents-Loaded Nanoparticles and Biomimetic Material in Ischemic Stroke.

Front Cell Neurosci 2022 11;16:868323. Epub 2022 Apr 11.

Department of Anesthesiology, First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou, China.

Ischemic stroke remains the leading cause of death and disability, while the main mechanisms of dominant neurological damage in stroke contain excitotoxicity, oxidative stress, and inflammation. The clinical application of many neuroprotective agents is limited mainly due to their inability to cross the blood-brain barrier (BBB), short half-life and low bioavailability. These disadvantages can be better eliminated/reduced by nanoparticle as the carrier of these drugs. Read More

Design and Fabrication of Polymeric Hydrogel Carrier for Nerve Repair.

Polymers (Basel) 2022 Apr 11;14(8). Epub 2022 Apr 11.

School of Materials Science and Engineering, Beijing Institute of Technology, Beijing 100081, China.

Nerve regeneration and repair still remain a huge challenge for both central nervous and peripheral nervous system. Although some therapeutic substances, including neuroprotective agents, clinical drugs and stem cells, as well as various growth factors, are found to be effective to promote nerve repair, a carrier system that possesses a sustainable release behavior, in order to ensure high on-site concentration during the whole repair and regeneration process, and high bioavailability is still highly desirable. Hydrogel, as an ideal delivery system, has an excellent loading capacity and sustainable release behavior, as well as tunable physical and chemical properties to adapt to various biomedical scenarios; thus, it is thought to be a suitable carrier system for nerve repair.

Therapeutic Induction of Collateral Flow.

Transl Stroke Res 2022 Apr 13. Epub 2022 Apr 13.

Department of Neurological Sciences, University of Vermont Robert Larner College of Medicine, 149 Beaumont Ave, HSRF 416A, Burlington, VT, USA.

Therapeutic induction of collateral flow as a means to salvage tissue and improve outcome from acute ischemic stroke is a promising approach in the era in which endovascular therapy is no longer time-dependent but collateral-dependent. The importance of collateral flow enhancement as a therapeutic for acute ischemic stroke extends beyond those patients with large amounts of salvageable tissue. It also has the potential to extend the time window for reperfusion therapies in patients who are ineligible for endovascular thrombectomy. Read More

Valproic Acid Inhibits Glial Scar Formation after Ischemic Stroke.

Pharmacology 2022 22;107(5-6):263-280. Epub 2022 Mar 22.

Jiangsu Key Laboratory of Neuropsychiatric Diseases, Department of Pharmacology and Laboratory of Cerebrovascular Pharmacology, College of Pharmaceutical Science, Jiangsu Key, Soochow University, Suzhou, China.

Introduction: Cerebral ischemia induces reactive proliferation of astrocytes (astrogliosis) and glial scar formation. As a physical and biochemical barrier, the glial scar not only hinders spontaneous axonal regeneration and neuronal repair but also deteriorates the neuroinflammation in the recovery phase of ischemic stroke.

Objectives: Previous studies have shown the neuroprotective effects of the valproic acid (2-n-propylpentanoic acid, VPA) against ischemic stroke, but its effects on the ischemia-induced formation of astrogliosis and glial scar are still unknown. Read More
