In Parkinson’s disease (PD), damaged mitochondria build up in the dopaminergic system of the substantia nigra, partly due to impaired mitochondrial autophagy (mitophagy) and autophagosome accumulation.
Nitrated α-synuclein is upregulated in the CSF of patients with Parkinson’s Disease (PD), Lewy body dementia (DLB), multiple system atrophy (MSA), and other synucleinopathies.
Researchers from Voyager Therapeutics Inc. presented preclinical activity data of VY-1706, a blood-brain barrier (BBB)-penetrant gene therapy comprising an adeno-associated virus serotype 9 capsid (AAV9-C9P39) vector encoding primary artificial microRNA (pri-amiRNA) consisting of short-interfering RNA (siRNA) targeting human microtubule-associated protein tau (MAPT) protein.
Metachromatic leukodystrophy (MLD) is an autosomal recessive lysosomal storage disease originating from biallelic pathogenic variants in the ARSA gene, mainly affecting young children.
Writing in Molecular Therapy Nucleic Acids, researchers hypothesized that using poly(A) tail mimetics to enhance mRNA expression from haploinsufficiency-associated genes could be a disease-modifying treatment strategy.
As developers continue to search for better amyotrophic lateral sclerosis (ALS) therapies, Neurosense Therapeutics Ltd. turned up some hopeful findings from its phase IIb Paradigm trial with PrimeC. The drug, a combination therapy (ciprofloxacin and celecoxib) designed to target multiple ALS pathways, is having salutary effects on microRNA modulation (miRNA), Neurosense said, with the study showing a “profound and consistent” downregulation of 161 mature miRNAs across all time points in the double-blind period of the experiment.
Remegen Co. Ltd. emerged as a surprise challenger in the generalized myasthenia gravis space, unveiling positive phase III data of its China-approved lupus drug, telitacicept (RCT-18; Tai’ai), in the rare autoimmune neuromuscular disorder at the 2025 American Academy of Neurology conference.
Researchers from Sanofi SA reported the preclinical characterization of SAR-446159 (ABL-301), a bispecific antibody construct comprising an antibody targeting α-synuclein fused to an engineered antibody fragment that targets IGF-1R and functions as a blood-brain barrier (BBB) shuttle, known as the Grabody-B platform.
BDNF is the brain’s most abundant neurotrophic factor, playing a key role in neuronal survival and synaptic plasticity through the activation of the transcription factor CREB, which is essential for driving beneficial effects in neurons. CREB is downregulated in Parkinson’s disease, Huntington’s disease, frontotemporal dementia, Alzheimer’s disease and other neurodegenerative conditions.
Transferrin receptor (TfR)-mediated transcytosis is a receptor-mediated mechanism for drug delivery to the brain or other tissues, where, after the antibody binds to transferrin, the therapeutic agent is internalized and released into the brain.
