Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder characterized by motor, social and cognitive deficits that develop early during childhood. The pathogenesis of ASD is not well characterized and involves a multifaceted interaction between genetic, neurobiological and environmental factors. Animal (experimental) models possess evolutionarily conserved behaviors and molecular pathways that are highly relevant for studying ASD. The zebrafish (Danio rerio) is a relatively new animal model with promise for understanding the pathogenesis of complex brain disorders and discovering novel treatments. As a highly social and genetically tractable organism, zebrafish have recently been applied to model a variety of deficits relevant to ASD. Here, we discuss the developing utility of zebrafish models of ASD, as well as current behavioral, toxicological and genetic models of ASD, and future directions of research in this field.

The accurate assembly of the ribonucleoprotein (RNP) complex is fundamental for the replication and transcription of rhabdoviruses, which are known for their broad pathogenic impact. A novel 119-amino-acid protein, NLRP12-119aa is identified, encoded by the circular RNA circNLRP12, that effectively disrupts the formation of rhabdovirus RNP complexes through two distinct mechanisms and significantly reduces their replication. NLRP12-119aa exhibits a strong affinity for the conserved 18-nucleotide sequence at the start of the leader RNA of rhabdoviruses VSV, SCRV, and RABV, outcompeting their native N protein interactions, thereby disrupting the assembly of RNP complexes and inhibiting viral replication.

Inflammation, a central process in numerous diseases, plays a crucial role in hepatic disorders, arthritis, cardiac conditions, and neurodegenerative ailments. Given the lack of effective anti-inflammatory drugs, it is imperative to assess inflammation severity and explore novel therapeutics. Selenocysteine (Sec), a key mediator of selenium's biological function, is closely involved in anti-inflammatory responses.

Identifying gene expression differences in heterogeneous tissues across conditions is a fundamental biological task, enabled by multi-condition single-cell RNA sequencing (RNA-seq). Current data analysis approaches divide the constituent cells into clusters meant to represent cell types, but such discrete categorization tends to be an unsatisfactory model of the underlying biology. Here, we introduce latent embedding multivariate regression (LEMUR), a model that operates without, or before, commitment to discrete categorization.

Lafora disease (LD) is an ultra-rare and still incurable neurodegenerative condition. Although several therapeutic strategies are being explored, including gene therapy, there are currently no treatments that can alleviate the course of the disease and slow its progression. Recently, gliflozins, a series of SGLT2 transporter inhibitors approved for use in type 2 diabetes mellitus, heart failure and chronic kidney disease, have been proposed as possible repositioning drugs for the treatment of LD.

Background: APOEε4 significantly increases the risk of developing Alzheimer's disease (AD). Cognitively healthy APOEε4-carriers exist, suggesting potential protective mechanisms against APOEε4. We hypothesized that some APOEε4-carriers may have genetic variations protecting them from developing APOEε4-mediated AD pathology.
