Glutamate transporter activator LDN-212320 prevents chronic pain-induced cognitive impairment and anxiety-like behaviors in a mouse model.

Behav Brain Res

January 2025

Department of Pharmaceutical Sciences, College of Pharmacy, South Dakota State University, Brookings, SD 57007, USA. Electronic address:

The astroglial glutamate transporter in the hippocampus and anterior cingulate cortex (ACC) is critically involved in chronic pain-induced cognitive and psychiatric abnormalities. We have previously reported that LDN-212320, a glutamate transporter-1 (GLT-1) activator, attenuates complete Freund's adjuvant (CFA)-induced acute and chronic nociceptive pain. However, the cellular and molecular mechanisms underlying GLT-1 modulation in the hippocampus and ACC during chronic pain-induced cognitive deficit-like and anxiety-like behaviors remain unknown.

Scope: Alzheimer's disease (AD) is the most prevalent form of dementia, lack of effective therapeutic interventions. In this study, we investigate the impact of intermittent fasting (IF), an alternative strategy of calorie restriction, on cognitive functions and AD-like pathology in a transgenic mouse model of AD.

Methods And Results: APP/PS1 mice at 6 months were randomly allocated to two dietary groups: one receiving ad libitum (AL) feeding and the other undergoing IF for 1 month.

Parkinson's disease (PD) stands as the sec most prevalent incapacitating neurodegenerative disorder characterized by deterioration of dopamine-producing neurons in the substantia nigra. Coenzyme Q10 (CoQ10) has garnered attention as a potential antioxidant, anti-inflammatory agent and enhancer of mitochondrial complex-I activity. This study aimed to examine and compare the effectiveness of liposomal and non-encapsulated CoQ10 in rotenone induced-PD mouse model over a 21-day treatment duration.

Single-Cell Insights Into Cellular Response in Abdominal Aortic Occlusion-Induced Hippocampal Injury.

CNS Neurosci Ther

January 2025

Beijing Key Laboratory of Hypoxia Translational Medicine, Xuanwu Hospital, Center of Stroke, Beijing Institute of Brain Disorder, Capital Medical University, Beijing, China.

Objective: Ischemia-reperfusion of the abdominal aorta often results in damage to distant organs, such as the heart and brain. This cellular heterogeneity within affected tissues complicates the roles of specific cell subsets in abdominal aorta occlusion model (AAO) injury. However, cell type-specific molecular pathology in the hippocampus after ischemia is poorly understood.

Background: Alzheimer's disease (AD) remains incurable, yet its long prodromal phase offers a crucial window for early intervention. Pretangle tau, a precursor to neurofibrillary tangles, plays a key role in early AD pathogenesis. Intervening in pretangle tau pathology could significantly delay the progression of AD.
