The neurotoxin 5,7-dihydroxytryptamine (5,7-DHT) is often used in neonatal rats to induce specific, rapid, and permanent depletion of brain serotonin (5-HT). One assumed benefit of using this drug in neonates is that it is well-tolerated, with pups exhibiting few side effects normally attributed to 5-HT depletion. Here, we present evidence that 5,7-DHT administered neonatally induces seizure-like behavior, decreases weight gain, and increases plasma corticosterone without depletion of brain 5-HT.

The BEN domain protein LIN-14 coordinates neuromuscular positioning during epidermal maturation.

iScience

Department of Neurobiology, School of Biological Sciences, University of California, San Diego, La Jolla, CA 92093, USA.

Development and function of an organism depend on coordinated inter-tissue interaction. How such interactions are maintained during tissue renewal and reorganization remains poorly understood. Here, we find that BEN domain transcription factor LIN-14 is required in epidermis for maintaining the position of motor neurons and muscles during developmental tissue reorganization.

Introduction: Age-associated depletion in nicotinamide adenine dinucleotide (NAD+) concentrations has been implicated in metabolic, cardiovascular, and neurodegenerative disorders. Supplementation with NAD+ precursors, such as nicotinamide riboside (NR), offers a potential therapeutic avenue against neurodegenerative pathologies in aging, Alzheimer's disease, and related dementias. A crossover, double-blind, randomized placebo (PBO) controlled trial was conducted to test the safety and efficacy of 8 weeks' active treatment with NR (1 g/day) on cognition and plasma AD biomarkers in older adults with subjective cognitive decline and mild cognitive impairment.

Ocrelizumab dose selection for treatment of pediatric relapsing-remitting multiple sclerosis: results of the OPERETTA I study.

J Neurol

Division of Child Neurology, Children's Hospital of Philadelphia, Departments of Neurology and Pediatrics, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA, USA.

Background: The presented study identified the appropriate ocrelizumab dosing regimen for patients with pediatric-onset multiple sclerosis (POMS).

Methods: Patients with POMS aged 10-17 years were enrolled into cohort 1 (body weight [BW] < 40 kg, ocrelizumab 300 mg) and cohort 2 (BW ≥ 40 kg, ocrelizumab 600 mg) during a 24-week dose-exploration period (DEP), followed by an optional ocrelizumab (given every 24 weeks) extension period.

Primary Endpoints: pharmacokinetics, pharmacodynamics (CD19 B-cell count); secondary endpoint: safety; exploratory endpoints: MRI activity, protocol-defined relapses, Expanded Disability Status Scale (EDSS) score change.

Proper polarization of newly generated neurons is a critical process for neural network formation and brain development. The pan-neurotrophin p75 receptor plays a key role in this process localizing asymmetrically in one of the differentiating neurites and specifying its axonal identity in response to neurotrophins. During axonal specification, p75 levels are transiently modulated, yet the molecular mechanisms underlying this process are not known.

Alzheimer's disease (AD) impacts millions of elderly adults worldwide causing cognitive decline and severe deterioration of activities of daily life. The popular causal hypotheses for several decades include beta-amyloid (Aβ) deposition and tau hyperphosphorylation. AD research and more than 34% of clinical trials in AD are based on these two hypotheses.
