Unraveling the pathogenic mechanism of a novel filamin a frameshift variant in periventricular nodular heterotopia.

Background: Periventricular nodular heterotopia (PVNH) is a neuronal migration disorder caused by the inability of neurons to move to the cortex. Patients with PVNH often experience epilepsy due to ectopic neuronal discharges. Most cases of PVNH are associated with variations in filamin A (), which encodes an actin-binding protein.

The Mechanisms of Mesenchymal Stem Cells in the Treatment of Experimental Autoimmune Encephalomyelitis.

Multiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system and is a leading cause of disability in young adults. Most therapeutic strategies are based on immunosuppressant effects. However, none of the drugs showed complete remission and may result in serious adverse events such as infection.

Obesity-induced oxidative stress and mitochondrial dysfunction negatively affect sperm quality.

Obesity is a systemic metabolic disease that can induce male infertility or subfertility through oxidative stress. The aim of this study was to determine how obesity impairs sperm mitochondrial structural integrity and function, and reduces sperm quality in both overweight/obese men and mice on a high-fat diet (HFD). Mice fed the HFD demonstrated higher body weight and increased abdominal fat content than those fed the control diet.

Enlarged perivascular spaces, neuroinflammation and neurological dysfunction in NMOSD patients.

Background And Objectives: Cerebrospinal fluid (CSF) and interstitial fluid exchange along a brain-wide network of perivascular spaces (PVS) termed the 'glymphatic system'. The aquaporin-4 (AQP4) water channels abundantly expressed on astrocytic endfeet play a key role in the CSF circulation in the glymphatic system. Neuromyelitis optica spectrum disorder (NMOSD) is an inflammatory demyelinating autoimmune disease of the central nervous system (CNS) featured with a specific autoantibody directed against AQP4 in most of patients.

Preclinical Studies on Neural Stem/Progenitor Cell Therapy for Ischemic Stroke: A Systematic Review.

Background: Neural stem/progenitor cells (NSPCs) transplantation has been recognized in recent years as an effective strategy for the treatment of ischemic stroke. Several preclinical studies have demonstrated the feasibility, safety, and efficacy of NSPCs therapy.

Methods: We conducted a systematic review of the published literature in Pubmed reporting the use of NSPCs in preclinical studies between 2010 and 2021.

Tracking Neural Stem Cells in vivo: Achievements and Limitations.

Neural stem cell (NSC) therapies are developing rapidly and have been proposed as a treatment option for various neurological diseases, such as stroke, Parkinson's disease and multiple sclerosis. However, monitoring transplanted NSCs, exploring their location and migration, and evaluating their efficacy and safety have all become serious and important issues. Two main problems in tracking NSCs have been noted: labeling them for visibility and imaging them.
