Background: Neuromyelitis optica spectrum disorders (NMOSD) is a severe immune-mediated inflammatory central nervous system (CNS) syndrome. YKL-40, as a new inflammatory marker, has been studied in many autoimmunity and CNS diseases. Our aim of this study was to investigate cerebrospinal fluid (CSF) and serum YKL-40 levels in patients with NMOSD and their association with disease severity.
Methods: We measured CSF and serum YKL-40 levels in 29 patients with NMOSD and 21 age- and sex-matched controls. We analyzed the associations between CSF YKL-40 levels and the clinical variables of NMOSD.
Results: Compared to controls, patients with NMOSD had significantly higher CSF YKL-40 levels. Moreover, CSF YKL-40 levels were positively correlated with the Expanded Disability Status Scale scores.
Conclusions: YKL-40 could be a NMOSD severity biomarker and a potential target for NMOSD treatment.

Background: Cerebrospinal fluid (CSF) β2-microglobulin (β2M) has been demonstrated as an important factor in β-amyloid (Aβ) neurotoxicity and a potential target for Alzheimer's disease (AD). However, more investigation is required to ascertain the relationship between β2M and glial activities in AD pathogenesis.
Methods: In this study, 211 participants from the Alzheimer's disease Neuroimaging Initiative (ADNI) with CSF and Plasma β2M, CSF glial fibrillary acidic protein (GFAP), soluble triggering receptor expressed on myeloid cells 2 (sTREM2), Aβ, phosphorylated-tau (P-tau) and total tau (T-tau) were divided into four groups, stage 0, 1, 2, and suspected non-AD pathology (SNAP) based on the National Institute on Aging- Alzheimer's Association (NIA-AA) criteria.

Background: Oesophageal cancer (EC) is one of the common malignant tumors, and the prognosis of patients is poor. Further exploration of EC pathogenesis remains warranted.
Objective: The relationship between vascular epithelial cadherin (VE-cadherin) and chitinase-3-like protein 1 (CHI3L1) in EC is currently unknown.

Background And Objectives: Blood-based biomarkers of amyloid and tau have been shown to predict Alzheimer disease (AD) dementia. Much less is known about their ability to predict risk of mild cognitive impairment (MCI), an earlier disease stage. This study examined whether levels of blood biomarkers of amyloid (Aβ/Aβ ratio), tau (p-tau), neurodegeneration (NfL), and glial activation and neuroinflammation (glial fibrillary acidic protein [GFAP], YKL40, soluble triggering receptor expressed on myeloid cells 2 [sTREM2]) collected when participants were cognitively normal are associated with the time to onset of MCI.

Aims: We investigated the association of the inflammatory biomarker YKL-40 with cardiovascular events (CVEs) and mortality in individuals with type 2 diabetes.
Methods: We followed 11,346 individuals recently diagnosed with type 2 diabetes for up to 14 years. Baseline YKL-40 levels (measured in 9,010 individuals) were grouped into percentiles (0-33 %, 34-66 %, 67-90 %, and 91-100 %) and analyzed continuously (per 1 SD log increment), with comparisons to CRP (measured in 9,644 individuals).

Background: Glioblastoma (GB) is the stage IV of glioma and mesenchymal GB represents the most common and malignant subtype characterized with elevated expression of a mesenchymal marker YKL-40 and resistance to immune drug therapy. Here, we determined if YKL-40 regulates kynurenine (Kyn) pathway (KP) metabolism that contributes to establishing an immune suppressive microenvironment in GB.
Methods: Tumor cells expressing YKL-40 from GB patients were isolated and activated cellular metabolisms were identified via gene microarray analysis.
