Background: Vertebrobasilar junction (VBJ) aneurysms are frequently associated with basilar artery variations like fenestration or hypoplasia, altering hemodynamics. An interrupted aortic arch (IAA), a rare congenital malformation, may contribute to intracranial aneurysms via vascular wall defects, hemodynamic stress, and compensatory hypertension. Coexistence of IAA with cerebrovascular anomalies and VBJ aneurysms is exceptionally rare, with no prior documented cases.

Tripartite motif-containing protein 29 (TRIM29) is a regulator of tumor progression across multiple cancer types. However, its functional significance in glioblastoma (GBM) remains poorly defined. In this study, we investigated the biological roles of TRIM29 in GBM and elucidated its underlying molecular mechanisms.

Glioblastoma (GBM) exhibits elevated TRIM22 expression correlated with tumor progression, as validated in TCGA/GEO databases. The effects of TRIM22 knockdown and overexpression on GBM proliferation were evaluated with cellular assays. TRIM22 was identified as a potential Bcl-2 activator via a ubiquitination microarray.

Glioblastoma (GBM) is the most aggressive primary intracranial tumor, with glioblastoma stem cells (GSCs) enforcing the intratumoral hierarchy. The inflammatory microenvironment influences tumor development at varying stages, while the underlying mechanism of GSCs facing pro-inflammatory stress remains unclear. Here, we show that, in human GBM, pro-inflammatory stress from pro-inflammatory macrophages (pTAMs) maintains GSC proliferation and self-renewal.

Glioma cells exhibit high invasiveness and have the ability to evade surgical resection, radiotherapy, and chemotherapy, which are major factors contributing to the challenges in effective treatment and recurrence. The ubiquitin-proteasome system (UPS) plays a crucial role in posttranslational modification, significantly contributing to the aggressive progression of glioblastoma (GBM). This study identified the E3 ubiquitin ligase CBLB as a crucial and abnormally regulated component of the UPS in GBM, noting its significant downregulation compared to normal brain tissue and its negative correlation with malignant phenotypes and poor prognosis.

Background And Importance: Enterogenic cysts often occur along the spinal axis and are frequently associated with congenital spinal malformations. The special location of the lesion can limit the surgical resection to achieve complete removal. In this report, the authors describe a successful case of complete resection of a ventral enterogenic cyst in the cervical spinal cord using a posterior midline approach in the lateral position.

Glioblastoma is a highly aggressive primary brain tumor with glioblastoma stem cells (GSCs) enforcing the intra-tumoral hierarchy. Plasma cells (PCs) are critical effectors of the B-lineage immune system, but their roles in glioblastoma remain largely unexplored. Here, we leverage single-cell RNA and B cell receptor sequencing of tumor-infiltrating B-lineage cells and reveal that PCs are aberrantly enriched in the glioblastoma-infiltrating B-lineage population, experience low level of somatic hypermutation, and are associated with poor prognosis.

Article Synopsis
  • Mixed lineage kinases (MLKs), part of the MAP3K family, are linked to cancer progression but their specific functions in glioblastoma (GBM) remain unclear.
  • Our study used bioinformatics to assess MLK expression in low-grade gliomas and GBM, revealing that MLK1-2 are downregulated in GBM and correlate with better patient survival, while ZAK's expression rises in contrast.
  • We developed a risk score model for predicting patient outcomes and confirmed the antitumor effects of MLK1-2, suggesting their potential as therapeutic targets in glioma treatment.

ARHGAP family genes are often used as glioma oncogenic factors, and their mechanism of action remains unexplained. Our research entailed a thorough examination of the immune microenvironment and enrichment pathways across various glioma subtypes. A distinctive 6-gene signature was developed employing the CGGA cohort, leading to insights into the disparities in clinical characteristics, mutation patterns, and immune cell infiltration among distinct risk categories.

Article Synopsis
  • The study investigates the role of macrophage migration inhibitory factors (MIFs) as potential biomarkers for cerebral small vessel disease with cognitive impairment (CSVD-CI).
  • The research involved 171 participants, including healthy controls and patients with CSVD-CI or CSVD but cognitively normal, who underwent various assessments and imaging tests.
  • Findings revealed that CSVD-CI patients had significantly higher plasma MIF levels, correlating with cognitive decline and brain health indicators, suggesting that elevated MIF levels could help identify CSVD-CI early and may be linked to cognitive issues caused by blood-brain barrier dysfunction.

Background: Experimental investigations have reported the efficacy of marrow mesenchymal stem cell-derived exosomes (MSC-Exos) for the treatment of ischemic stroke. The therapeutic mechanism, however, is still unknown. The purpose of the study is to show whether MSC-Exos increases astrocytic glutamate transporter-1 (GLT-1) expression in response to ischemic stroke and to investigate further mechanisms.

Article Synopsis
  • No reliable biomarker currently exists for early detection of cognitive impairment due to cerebral small vessel disease (CSVD) in older adults.
  • The study investigates the role of neutrophil extracellular traps (NETs) in blood and brain inflammation, finding elevated levels of specific NETs markers in CSVD patients compared to healthy controls, which correlate with cognitive performance.
  • Results suggest that plasma NETs could serve as potential biomarkers for diagnosing cognitive impairment in CSVD, highlighting the relationship between inflammation, oxidative stress, and cognitive decline.

Background: Cerebral small vessel disease (CSVD) is a cluster of microvascular disorders with unclear pathological mechanisms. The microbiota-gut-brain axis is an essential regulatory mechanism between gut microbes and their host. Therefore, the compositional and functional gut microbiota alterations lead to cerebrovascular disease pathogenesis.

Background: The lack of a well-designed brain tumour registry with standardized pathological diagnoses in underdeveloped countries hinders the ability to compare epidemiologic data across the globe. The National Brain Tumour Registry of China (NBTRC), created in January 2018, is the first multi-hospital-based brain tumour registry in China. Patient data reported to the NBTRC in years 2019-2020 were assessed.

Background: Non-valvular atrial fibrillation (NVAF) is the most common cause of cardiogenic cerebral embolism (CCE). However, the underlying mechanism between cerebral embolism and NVAF is indefinite, and there is no effective and convenient biomarker to identify potential risk of CCE in patients with NVAF in clinic. The present study aims to identify risk factors for interpreting the potential association of CCE with NVAF and providing valuable biomarkers to predict the risk of CCE for NVAF patients.

Astrocytes (AST) are abundant glial cells in the human brain, accounting for approximately 20-50% percent of mammalian central nervous system (CNS) cells. They display essential functions necessary to sustain the physiological processes of the CNS, including maintaining neuronal structure, forming the blood-brain barrier, coordinating neuronal metabolism, maintaining the extracellular environment, regulating cerebral blood flow, stabilizing intercellular communication, participating in neurotransmitter synthesis, and defending against oxidative stress et al. During the pathological development of brain tumors, stroke, spinal cord injury (SCI), neurodegenerative diseases, and other neurological disorders, astrocytes undergo a series of highly heterogeneous changes, which are called reactive astrocytes, and mediate the corresponding pathophysiological process.

Sustained activation of signal transducer and activator of transcription 3 (STAT3) is a critical contributor in tumorigenesis and chemoresistance, thus making it an attractive cancer therapeutic target. Here, SH2 domain-containing adapter protein F (SHF) is identified as a tumor suppressor in glioblastoma Multiforme (GBM) and its negative regulation of STAT3 activity is characterized. Mechanically, SHF selectively binds and inhibits acetylated STAT3 dimerization without affecting STAT3 phosphorylation or acetylation.
