Abstract
Hydrocephalus, a pathological condition due to the accumulation of cerebrospinal fluid (CSF) in the brain's ventricles, has been recognised as a relatively common brain abnormality in newborns and young adults with or without craniofacial anomaly. It can cause physical, behavioural and cognitive symptoms and, in severe cases, may result in lethality. Hydrocephalus can result from various underlying conditions, and its multifactorial nature makes pinpointing a single pathophysiological aetiology challenging. Notably, the relatively high prevalence of hydrocephalus (up to 100%) in the cranial neural crest cells (CNCCs) conditional knockout mouse models of various genes using Wnt1-Cre has been reported, given the extremely low (0.01% to 0.86%) spontaneous occurrence of hydrocephalus in different strains of lab mice. Surprisingly, there were no reports on the connections of hydrocephalus with CNCCs, although the prominent role of CNCCs in normal development and pathologic conditions of craniofacial and neural tissues has been extensively studied and highly recognised. In this review, besides revealing the high prevalence of hydrocephalus (5.4%-100%), we primarily summarised the in vivo findings of hydrocephalus and the associated pathological changes of brain and craniofacial skeletal tissues with the genetically modified mouse (GMM) models of various genes knocked out in CNCCs. Significantly, the functional gene knockout in Wnt1 expressing cells can lead to hydrocephalus and associated brain and craniofacial skeletal pathologies, irrespective of the ectopic midbrain Wnt1 activation observed in Wnt1-Cre driver mice. However, the specific contributions and underpinning mechanisms of the main structures of the CSF system, including CNCCs-derived choroid plexus, to hydrocephalus pathophysiology are yet to be fully elucidated.
期刊介绍:
Orthodontics & Craniofacial Research - Genes, Growth and Development is published to serve its readers as an international forum for the presentation and critical discussion of issues pertinent to the advancement of the specialty of orthodontics and the evidence-based knowledge of craniofacial growth and development. This forum is based on scientifically supported information, but also includes minority and conflicting opinions.
The objective of the journal is to facilitate effective communication between the research community and practicing clinicians. Original papers of high scientific quality that report the findings of clinical trials, clinical epidemiology, and novel therapeutic or diagnostic approaches are appropriate submissions. Similarly, we welcome papers in genetics, developmental biology, syndromology, surgery, speech and hearing, and other biomedical disciplines related to clinical orthodontics and normal and abnormal craniofacial growth and development. In addition to original and basic research, the journal publishes concise reviews, case reports of substantial value, invited essays, letters, and announcements.
The journal is published quarterly. The review of submitted papers will be coordinated by the editor and members of the editorial board. It is policy to review manuscripts within 3 to 4 weeks of receipt and to publish within 3 to 6 months of acceptance.
