Cover: Whole-mount immunostained brain of a 9-day-old zebrafish showing different cellular markers, acquired using a Zeiss Lightsheet fluorescent microscope. Glutamate receptors on neurons and glial cells are in green, phalloidin stain for actin fibers is in red, DAPI stain for nuclear localization is in cyan and the enzyme, glutamine synthetase, is in blue. Expression of these, particularly glutamine synthetase, is reduced under hyperglycemia, a prominent pathology of diabetes. The authors show that this deficiency can be ameliorated by nitric oxide supplementation. See article by Chhabria et al. (dmm039867). Image courtesy of Karishma Chhabria.

FIRST PERSON
AT A GLANCE
Modeling hematopoietic disorders in zebrafish
Summary: This At A Glance article and poster summarize the last 20 years of research in zebrafish models for hematopoietic disorders, highlighting how these models were created and are being applied for translational research.
REVIEW
Experimental models and tools to tackle glioblastoma
Summary: This Review discusses preclinical modelling of glioblastoma multiforme to understand its biology and develop therapies, with a focus on mammalian model systems.
RESEARCH ARTICLES
Sodium nitroprusside prevents the detrimental effects of glucose on the neurovascular unit and behaviour in zebrafish
Summary: Diabetes is associated with vascular and neurological impairments. The authors show that an NO donor ameliorates the glucose-exposure-induced dysfunction in the tectal neurovascular unit and whole-organism behaviour.
Insoluble Aβ overexpression in an App knock-in mouse model alters microstructure and gamma oscillations in the prefrontal cortex, affecting anxiety-related behaviours
Summary: Aβ overexpression in a second-generation Alzheimer's disease model results in alterations in anxiety-type behaviours, as well as gamma oscillations, neural organisation and Grin2b expression in the prefrontal cortex.
Therapeutic targeting of Notch signaling and immune checkpoint blockade in a spontaneous, genetically heterogeneous mouse model of T-cell acute lymphoblastic leukemia
Summary: Adapting a spontaneous, genetically heterogenous T-ALL model to preclinical testing demonstrated that response to therapeutic anti-Notch1 antibodies was determined by Notch1 mutational status and that PD-1 immune checkpoint blockade alone lacked anti-tumor activity.
A new mouse model of GLUT1 deficiency syndrome exhibits abnormal sleep-wake patterns and alterations of glucose kinetics in the brain
Summary: New phenotypes are revealed by a GLUT1 deficiency mutant mouse model carrying a missense mutation in Glut1.
Keeping Candida commensal: how lactobacilli antagonize pathogenicity of Candida albicans in an in vitro gut model
Editor's choice: Using antagonistic lactobacilli, C. albicans pathogenicity was reduced to a minimum in an in vitro gut model consisting of enterocytes and goblet cells.
Clinical pathologies of bone fracture modelled in zebrafish
Summary: The effect of osteogenesis imperfecta, bisphosphonate treatment and bacterial infection on phases of bone fracture repair are determined using a zebrafish fracture model.

-HUBSwebinar.jpg?versionId=4492)
Would you like to increase the visibility and impact of your research and raise your profile internationally? If so, register for the very practical webinar we are running in association with HUBS on 23 February 2023.
Live imaging adult disease processes

The optical transparency of zebrafish larvae facilitates live imaging, but this transparency is not maintained into adulthood. To address this, Pui-Ying Lam’s Resource Article demonstrates the feasibility of imaging adult Danionella cerebrum. This article has been highlighted as our Editor’s Choice by Kristen Kwan.
