Aim: Oligodendrocyte abnormalities are thought to be one of the key cellular pathologies involved in disturbances of neuronal connectivity in schizophrenia.
Material And Methods: The density of oligodendrocytes in layer III of the prefrontal cortex, BA10, in schizophrenia (n=20) was compared to controls (n=20) using optical dissector method. MANCOVA was applied for group comparisons.
Results And Conclusion: The density of oligodendrocytes was significantly lower in each sublayers of layer III (≤20% p≤0.05) in the schizophrenia group as compared to the control group. The deficit of oligodendrocytes in the prefrontal cortex in schizophrenia may be of developmental origin or the result of alterations in the neural tissue of the brain during disease course.

Background: In Alzheimer's disease (AD), specific brain regions become vulnerable to pathology while others remain resilient. New methods of imaging such as highly multiplexed immunofluorescence (MxIF) provide an abundance of spatial information, while analytical techniques like machine learning (ML) can address questions of cellular contributors to this regional vulnerability.
Method: We performed MxIF staining for 26 markers and compared postmortem human samples from an AD-susceptible brain area, the prefrontal cortex (PFC, Brodmann's areas 9, 10 or 46) to an AD-resilient brain area, the primary visual cortex (V1, area 17).
Cytosolic phospholipase A2 in infiltrating monocyte derived macrophages does not impair recovery after spinal cord injury in female mice.

Spinal cord injury (SCI) leads to permanent motor and sensory loss that is exacerbated by intraspinal inflammation and persists months to years after injury. After SCI, monocyte-derived macrophages (MDMs) infiltrate the lesion to aid in myelin-rich debris clearance. During debris clearance, MDMs adopt a proinflammatory phenotype that exacerbates neurodegeneration and hinders recovery.

White matter injury (WMI) is a common complication of preterm birth, potentially resulting in long-term behavioral and motor abnormalities. The objective of this study is to investigate the neuroprotective effects of glycyrrhizin (GLY) on WMI, and try to elucidate the potential mechanisms. In vivo chronic hypoxia-induced WMI mouse model and in vitro oxygen-glucose deprivation (OGD) induced WMI cell model were established, and the effects of GLY on WMI were explored through multiple assays, such as western blotting, immunofluorescence, immunohistochemistry, behavioral experiments, real-time quantitative polymerase chain reaction (RT-qPCR), transmission electron microscope (TEM), molecular docking, and bioinformatics analysis.

Background: Previous studies have reported that running exercise could improves myelinization in hippocampus. However, the effects of running exercise on the differentiation and maturation of oligodendrocytes, and myelination surrounding Aβ plaques in the medial prefrontal cortex (mPFC) of the Alzheimer's disease (AD) brain have not been reported.
Methods: Forty 10-month-old male APP/PS1 AD mice were randomly divided into the AD group and the AD running (AD+RUN) group, while 20 age-matched wild-type littermate mice were included in the WT group.
Pharmacological Blockade of Group II Metabotropic Glutamate Receptors Reduces the Incidence of Brain Tumors Induced by Prenatal Exposure to N-ethyl-N-nitrosourea in Rats.

Background: The study demonstrates that pharmacological blockade of type 3 metabotropic glutamate (mGlu3) receptors at the time of tumor induction significantly reduces the incidence of brain gliomas in rats. The overall survival of patients with high-grade brain gliomas is 14-20 months after current multimodal therapy, including surgery, radiotherapy, and adjuvant chemotherapy.
Objective: To demonstrate in this experimental model that pharmacological blockade of group II metabotropic glutamate receptors reduces the incidence of brain tumors induced by prenatal exposure to N- ethyl-N-nitrosourea (ENU) in rats.
