Article Synopsis
- The purpose of the study was to evaluate new human genes and variants related to ocular congenital cranial dysinnervation disorders (oCCDDs) using genetic sequencing methods.
- Researchers prioritized 43 human genes and 57 zebrafish genes through CRISPR/Cas9 knockout assays in zebrafish, ultimately generating mutants for 17 of those genes.
- The study identified three novel genes linked to cranial motor development and demonstrated that certain human gene variants may impair protein function, suggesting they could contribute to oCCDDs.
Article Synopsis
- This study aimed to identify the genetic causes and associations between genotype and phenotype in patients with unsolved ocular congenital cranial dysinnervation disorders (oCCDDs).
- Researchers analyzed data from 467 individuals with oCCDDs using exome or genome sequencing, revealing pathogenic variants in 43 probands and variants of uncertain significance in 70 others.
- The findings highlight the genetic diversity of oCCDDs and suggest that they may overlap with other genetic conditions, paving the way for further research on potential genetic links.
Purpose: To identify genetic etiologies and genotype/phenotype associations for unsolved ocular congenital cranial dysinnervation disorders (oCCDDs).
Methods: We coupled phenotyping with exome or genome sequencing of 467 pedigrees with genetically unsolved oCCDDs, integrating analyses of pedigrees, human and animal model phenotypes, and variants to identify rare candidate single nucleotide variants, insertion/deletions, and structural variants disrupting protein-coding regions. Prioritized variants were classified for pathogenicity and evaluated for genotype/phenotype correlations.
Opioid use disorder (OUD) has become a public health crisis, with recent significant increases in the number of deaths due to overdose. Vaccination can provide an attractive complementary strategy to combat OUD. A key for high vaccine efficacy is the induction of high levels of antibodies specific to the drug of abuse.

This is partly because most LHA neurons simultaneously promote feeding and drinking, suggesting that ingestive behaviors track together. A notable exception are LHA neurons expressing neurotensin (LHA neurons): activating these neurons promotes water intake but modestly restrains feeding.
View Article and Find Full Text PDFNeurotensin (Nts) is a neuropeptide implicated in the regulation of many facets of physiology, including cardiovascular tone, pain processing, ingestive behaviors, locomotor drive, sleep, addiction and social behaviors. Yet, there is incomplete understanding about how the various populations of Nts neurons distributed throughout the brain mediate such physiology. This knowledge gap largely stemmed from the inability to simultaneously identify Nts cell bodies and manipulate them .
