Published: December 2024

The neuronal ceroid lipofuscinoses, commonly known as Batten disease, are a group of lysosomal storage disorders affecting children. There is extensive central nervous system and retinal degeneration, resulting in seizures, vision loss and a progressive cognitive and motor decline. Enzyme replacement and gene therapies are being developed, and mRNA and oligonucleotide therapies are more recently being considered. Overcoming the challenges of the blood-brain barrier and blood-ocular barrier is crucial for effectively targeting the brain and eye, whatever the therapeutic approach. Nanoparticles and extracellular vesicles are small carriers that can encapsulate a cargo and pass through these cell barriers. They have been investigated as drug carriers for other pathologies and could be a promising treatment strategy for Batten disease. Their use in gene, enzyme, or mRNA replacement therapy of all lysosomal storage disorders, including Mucopolysaccharidoses, Niemann-Pick diseases, and Fabry disease, is investigated in this systematic review. Different nanocarriers can efficiently target the lysosome and cross the barriers into the brain and eyes. This supports continued exploration of nanocarriers as potential future treatment options for Batten disease.

Background: This study evaluated the clinical characteristics of neuronal ceroid lipofuscinosis type 7 or CLN7 disease spectrum to characterize the clinical, electrophysiologic and neuroimaging phenotypes.

Methods: We performed a single-center cross sectional data collection along with retrospective medical chart review in patients with a genetic diagnosis of CLN7. This study received ethical approval by the University of Texas Southwestern Medical Center Institutional Review Board.

The infantile neuronal ceroid lipofuscinosis, also called CLN1 disease, is a fatal neurodegenerative disease caused by mutations in the CLN1 gene encoding palmitoyl protein thioesterase 1 (PPT1). Identifying the depalmitoylation substrates of PPT1 is crucial for understanding CLN1 disease. In this study, we found that GABAR, the critical synaptic protein essential for inhibitory neurotransmission, is a substrate of PPT1.

Background: Bluetongue virus serotype 3 (BTV-3) was detected for the first time in cattle and sheep in southern England in 2023, the first UK BTV incursion for more than 15 years. Clinical signs were not observed, yet severe clinical disease and mortality were reported during recent BTV-3 outbreaks in northern Europe.

Methods: To investigate the clinical disease and infection kinetics associated with this UK BTV-3 strain, five British sheep were infected with a UK BTV-3 isolate using Culicoides biting midges.

Background: Neuronal ceroid lipofuscinoses (NCLs) are progressive, autosomal recessive lysosomal storage disorders primarily affecting children, marked by seizures, cognitive decline, motor regression, and visual impairment. Limited genetic data exist for South Asian populations, with most studies relying on enzymatic assays or electron microscopy. This study explores the genetic spectrum of NCL and genotype-phenotype correlations in a cohort from South India.
