Cover: Confocal microscopy image showing immunoreactive glial fibrillar acidic protein (GFAP; red) and amyloid precursor protein (APP; green) in rat primary control cultured astrocytes. See article by Wu et al. (dmm048929), which describes that exosomes derived from cholesterol-accumulated astrocytes can play an important role in trafficking APP and its cleaved product β-amyloid peptide, which can subsequently be taken up and influence the viability of neurons.

EDITOR'S CHOICE
EDITORIAL
Hot to touch: the story of the 2021 Nobel Prize in Physiology or Medicine
Summary: This year’s Nobel Prize in Physiology or Medicine celebrates how even the most fundamental of science can lead to broad applications for improving health and wellbeing.
REVIEWS
Infant leukaemia – faithful models, cell of origin and the niche
Summary: In this Review we discuss how MLL gene rearrangements cooperate with transient facilitators presented by the foetal environment to initiate the development of infant leukaemia, and evaluate current leukaemia models.
Genetically altered animal models for ATP1A3-related disorders
Summary: This Review provides an overview of the animal models used to study the spectrum of ATP1A3-related disorders and discusses their contribution towards better understanding of pathological mechanisms and novel therapeutics.
RESEARCH ARTICLES
Implications of exosomes derived from cholesterol-accumulated astrocytes in Alzheimer's disease pathology
Summary: Cholesterol accumulation within astrocytes can influence secretion of exosomes containing β-amyloid-related peptides. Uptake of these exosomes can induce neurotoxicity, suggesting their potential implication in Alzheimer's disease pathogenesis.
Rapamycin modulates pulmonary pathology in a murine model of Mycobacterium tuberculosis infection
Summary: Rapamycin, an mTOR inhibitor, with or without moxifloxacin, reduces lung inflammation and the number and size of caseating necrotic granulomas in Mycobacterium tuberculosis-infected C3HeB/FeJ mice.
Morc2a p.S87L mutant mice develop peripheral and central neuropathies associated with neuronal DNA damage and apoptosis
Summary: We present a new mouse model of Charcot-Marie-Tooth disease type 2 Z and developmental delay, impaired growth, dysmorphic facies and axonal neuropathy syndrome with a Morc2a p.S87L mutation, exhibiting peripheral and central neuronal apoptosis.
Development and characterization of an animal model of Japanese encephalitis virus infection in adolescent C57BL/6 mouse
Summary: We generated a mouse-adapted Japanese encephalitis virus (JEV) isolate to develop and characterize a mouse model of JEV infection, which could be a useful tool to screen antivirals and study JEV pathogenesis.
Integrative transcriptomic profiling of a mouse model of hypertension-accelerated diabetic kidney disease
Summary: Combining single-nucleus RNAseq with glomerular and cortical gene expression profiling can link kidney transcriptome signatures to specific cell types in an advanced mouse model of hypertension-accelerated diabetic kidney disease.
Propensity to endoplasmic reticulum stress in deer mouse fibroblasts predicts skin inflammation and body weight gain
Summary: Using outbred deer mice, we show that the unfolded protein response operates as a modifier of propensity for body weight gain in a manner involving the regulation of an inflammatory response by skin fibroblasts.
Comprehensive phenotypic analysis of the Dp1Tyb mouse strain reveals a broad range of Down syndrome-related phenotypes
Editor's choice: Comprehensive phenotyping shows that Dp1Tyb mice, a model of Down syndrome (DS), have a broad range of DS-related phenotypes and can be used to investigate causative genes and their pathological mechanisms.
RESOURCE ARTICLE
Flow cytometry allows rapid detection of protein aggregates in cellular and zebrafish models of spinocerebellar ataxia 3
Summary: Description of a flow cytometric methodology for the rapid detection and quantification of detergent-insoluble protein aggregates within cultured cells and transgenic zebrafish modelling spinocerebellar ataxia 3.
FIRST PERSON
Call for papers – In Vitro Models of Human Disease to Inform Mechanism and Drug Discovery

We invite you to submit your latest research to our upcoming special issue: In Vitro Models of Human Disease to Inform Mechanism and Drug Discovery, coordinated by DMM Editor Vivian Li (The Francis Crick Institute, London, UK), alongside Guest Editors Austin Smith (University of Exeter, UK) and Joseph Wu (Stanford University School of Medicine, USA).The deadline for submitting articles is 6 October 2025.
The Company of Biologists Workshops

For the last 15 years, our publisher, The Company of Biologists, has provided an apt environment to inspire biology and support biologists through our Workshops series. Read about the evolution of the Workshop series and revisit JEB's experience with hosting the first Global South Workshop.
Read & Publish Open Access publishing: what authors say

We have had great feedback from authors who have benefitted from our Read & Publish agreement with their institution and have been able to publish Open Access with us without paying an APC. Read what they had to say.
Fast & Fair peer review

Our sister journal Biology Open has recently launched the next phase of their Fast & Fair peer review initiative: offering high-quality peer review within 7 working days. To learn more about BiO’s progress and future plans, read the Editorial by Daniel Gorelick, or visit the Fast & Fair peer review page.
Propose a new Workshop for 2027

We are currently seeking proposals for Workshops to be held in 2027. As one of the scientific organisers of a The Company of Biologists Workshop, your involvement will be focused on interdisciplinary, cutting-edge science and promoting new partnerships and collaborations. We focus on the logistics. Are you thinking about proposing a topic for one of our Workshops? Apply by Friday 30 May 2025.
