Introduction: Immune-related adverse events (irAEs) induced by immune checkpoint inhibitors are difficult to predict and can lead to severe events. Although it is important to develop strategies for the early detection of severe irAEs, there is a lack of evidence on irAEs associated with ipilimumab plus nivolumab therapy for metastatic renal cell carcinoma (RCC). Therefore, this study aimed to investigate the association between eosinophil and severe irAEs in patients receiving ipilimumab plus nivolumab therapy for RCC.

The disease's trajectory of Alzheimer disease (AD) is associated with and negatively correlated to hippocampal hyperexcitability. Here, we show that during the asymptomatic stage in a knockin (KI) mouse model of Alzheimer disease (APP; APPKI), hippocampal hyperactivity occurs at the synaptic compartment, propagates to the soma, and is manifesting at low frequencies of stimulation. We show that this aberrant excitability is associated with a deficient adenosine tone, an inhibitory neuromodulator, driven by reduced levels of CD39/73 enzymes, responsible for the extracellular ATP-to-adenosine conversion.

Clinical and genetic spectrum of patients with IRF2BPL syndrome.

J Hum Genet

January 2025

Department of Human Genetics, Graduate School of Medicine, Yokohama City University, Yokohama, Japan.

Interferon regulatory factor 2 binding protein-like (IRF2BPL) is a single-exon gene that is ubiquitously expressed in various tissues, including the brain. IRF2BPL encodes a transcription factor with two zinc-finger domains that potentially downregulate WNT signaling in the nervous system. Pathogenic IRF2BPL variants have been reported to cause developmental delay, seizures, myoclonus epilepsies, autistic spectrum disorder, and other neurodevelopmental disorders.

Department of Developmental and Regenerative Neurobiology, Institute of Brain Science, Nagoya City University Graduate School of Medical Sciences, 1 Kawasumi, Mizuho-cho, Mizuho-ku, Nagoya, Aichi 467-8601, Japan.

Birth is one of the most important life events for animals. However, its significance in the developmental process is not fully understood. Here, we found that birth-induced alteration of glutamine metabolism in radial glia (RG), the embryonic neural stem cells (NSCs), is required for the acquisition of quiescence and long-term maintenance of postnatal NSCs.

A refined method for high-purity isolation of uterine glandular epithelial cells in mouse.

J Biochem

January 2025

Department of Comparative and Experimental Medicine, Graduate School of Medical Sciences, Nagoya City University, Nagoya, Japan.

The uterine endometrium consists of luminal epithelium, glandular epithelium, and stromal cells, with uterine glands playing a pivotal role in pregnancy success among mammals. Uterine glands secrete essential factors that regulate embryo development and implantation; however, their cellular biology remains poorly understood. This study presents a refined method for isolating three distinct endometrial cell types with high purity, with a specific emphasis on glandular epithelial cells.

In the ventricular-subventricular-zone (V-SVZ) of the postnatal mammalian brain, immature neurons (neuroblasts) are generated from neural stem cells throughout their lifetime. These V-SVZ-derived neuroblasts normally migrate to the olfactory bulb through the rostral migratory stream, differentiate into interneurons, and are integrated into the preexisting olfactory circuit. When the brain is injured, some neuroblasts initiate migration toward the lesion and attempt to repair the damaged neuronal circuitry, but their low regeneration efficiency prevents functional recovery.

This case study details a 41-year-old male patient with Freeman-Sheldon syndrome (FSS) who presented with ocular hypertension. The intraocular pressure (IOP) in his right eye progressively increased over time, leading to visual field loss, culminating in a diagnosis of juvenile-onset open-angle glaucoma (JOAG). Despite conventional medical therapies, adequate IOP control was not achieved, necessitating his referral to Nagoya City University Hospital.

Unlabelled: Mitral annular calcification (MAC) is a chronic degenerative process involving the fibrous support structure of the mitral valve. The prevalence of this condition significantly increases with age, and is higher in patients with cardiovascular risk factors or end-stage renal disease. However, patients with systemic lupus erythematosus (SLE) may develop atherosclerosis and MAC at a relatively young age.

Maternal circadian rhythms during pregnancy dictate metabolic plasticity in offspring.

Cell Metab

January 2025

Division of Endocrinology, Metabolism, and Nephrology, Department of Internal Medicine, Keio University School of Medicine, Tokyo, Japan; Center for Preventive Medicine, Keio University, Tokyo, Japan. Electronic address:

Tissue-level oscillation is achieved by tissue-intrinsic clocks along with network-dependent signals originating from distal organs and organismal behavior. Yet, it remains unexplored whether maternal circadian rhythms during pregnancy influence fetal rhythms and impact long-term susceptibility to dietary challenges in offspring. Here, we demonstrate that circadian disruption during pregnancy decreased placental and neonatal weight yet retained transcriptional and structural maturation.

Right ventricular (RV) dysfunction after biventricular repair is critical in most adults with congenital heart disease (ACHD). Conventional 2D magnetic resonance imaging (MRI) measurement is considered as a 'gold standard' for RV evaluation; however, addition information on ACHD after biventricular repair is sometimes required. The reasons why adjunctive information is required is as follows: (I) to evaluate the severity of cardiac burden in symptomatic patients with normal RV size and ejection fraction (EF), (II) to determine the optimal timing of invasive treatments in asymptomatic ones, and (III) to detect proactively a potential cardiac burden leading to ventricular deterioration, from a fluid dynamics perspective.

In illicit drug markets, the most recently expanding new synthetic opioid subclass is benzimidazoles, also known as nitazenes, which were originally developed as analgesics in the 1950s. The emergence of this classical, potent drug family has attracted extensive research interest in the field of forensic toxicology; however, information on their psychological and physical dependence is very limited. Herein, we evaluated the rewarding effects of four nitazene analogs using a battery of in vivo experiments, with a positive control drug (isotonitazene).
