Bibliometric analysis of neuroinflammation and Alzheimer's disease.

Background: Alzheimer's disease (AD) is the predominant cause of dementia on a global scale, significantly impacting the health of the elderly population. The pathogenesis of AD is closely linked to neuroinflammation. The present study employs a bibliometric analysis to examine research pertaining to neuroinflammation and AD within the last decade, with the objective of providing a comprehensive overview of the current research profile, hotspots and trends. Methods: This research conducted a comprehensive review of publications within the Science Citation Index Expanded of the Web of Science Core Collection Database spanning the years 2014 to 2024. Bibliometric analyses were performed using VOSviewer (version 1.6.19) and CiteSpace (version 6.3.R1) software to visualize data on countries, institutions, authors, journals, keywords, and references. Results: A total of 3,833 publications on neuroinflammation and AD were included from January 2014 to January 2024. Publications were mainly from the United States and China. Zetterberg, Henrik emerged as the author with the highest publication output, while Edison, Paul was identified as the most cited author. The most productive journal was Journal of Alzheimers Disease, and the most co-cited was Journal of Neuroinflammation. Research hotspot focused on microglia, mouse models, oxidative stress, and amyloid-beta through keyword analysis. Additionally, keywords such as blood-brain barrier and tau protein exhibited prolonged citation bursts from 2022 to 2024. Conclusion: This study provides a comprehensive review of the last 10 years of research on neuroinflammation and AD, including the number and impact of research findings, research hotspots, and future trends. The quantity of publications in this field is increasing, mainly in the United States and China, and there is a need to further strengthen close cooperation with different countries and institutions worldwide. Presently, research hotspots are primarily concentrated on microglia, with a focus on inhibiting their pro-inflammatory responses and promoting their anti-inflammatory functions as a potential direction for future investigations.

Generation of human induced pluripotent stem cell line (XWHNi004-A) from a male with APOE gene mutation.

Genetic polymorphism of apolipoprotein E (APOE) confers differential susceptibility to Alzheimer's disease (AD), and APOE ɛ4 variants is the most powerful risk factor for this disease. Here, we report the generation of a human induced pluripotent stem cell (iPSC) line carrying the APOE ɛ4/ɛ4 genotype from peripheral blood mononuclear cells (PBMCs) isolated from a male with a family history of AD utilizing non-integrative Sendai virus vector. The iPSC maintains their original genotype, highly express endogenous pluripotency markers, displays a normal karyotype, and retains the ability to differentiate into cells representative of the three germ layers.

Efficacy and safety of butylphthalide in patients with mild cognitive impairment: a multicentre, randomised, double-blind, placebo-controlled trial (EBMCI study).

INTRODUCTION: The efficacy of multitarget neuroprotective drug DL-3-n-butylphthalide (NBP) in improving cognitive function has been confirmed in patients with vascular cognitive impairment without dementia. However, its efficacy in patients with symptomatic predementia phase of Alzheimer's disease remains uncertain. This study aims to evaluate the efficacy and safety of NBP in improving cognitive function in patients with mild cognitive impairment (MCI) through a clinical randomised controlled trail. METHODS AND ANALYSIS: This study is a 12-month, randomised, double-blind, placebo-controlled, multicentric trial, involving 270 patients with MCI. Subjects are randomly assigned to receive either NBP soft capsule (200 mg, three times per day) or placebo with an allocation ratio of 1:1. The efficacy and safety of NBP are assessed by comparing the results of neuropsychological, neuroimaging and laboratory tests between the two groups. The primary endpoint is the change in Alzheimer's Disease Assessment Scale-Cognitive Subscale after 12 months. All patients will be monitored for adverse events. ETHICS AND DISSEMINATION: This study involving human participants has been reviewed and approved by Ethics Committee of Xuan Wu Hospital (No.2017058). The participants provide their written informed consent to participate in this study. Results will be published in peer-reviewed medical journals and disseminated to healthcare professionals at local and international conferences. PROTOCOL VERSION: V 3.0, 3 September 2022. TRIAL REGISTRATION NUMBER: ChiCTR1800018362.

Generation of induced pluripotent stem cell line (XWHNi003-A) from a female with APOE gene mutation.

Apolipoprotein E (APOE)is the gene with greatest genetic risk for Alzheimer's disease (AD). We successfully established a human induced pluripotent stem cell(iPSC) line from a woman mutated by APOE gene. The cell line was isolated from this woman's peripheral blood mononuclear cells using a non-integrated Sendai virus, which retained the original genotype, showed a normal karyotype, highly expressed pluripotent markers and could differentiate into three germ layers.

Generation of induced pluripotent stem cell line (XWHNi002-A) from a female with APP gene mutation.

The ß-amyloid precursor protein (APP) is a crucial pathogenic gene linked to Alzheimer's disease (AD). A human induced pluripotent stem cell (iPSC) line was generated from peripheral blood mononuclear cells (PBMCs) isolated from a female with APP gene mutation utilizing non-integrative Sendai virus. The iPSC line exhibits high expression of pluripotency markers, retains the APP mutation, displays a normal karyotype, and has the ability to differentiate into normal teratoma tissue. This iPSC line represents a valuable cell model for investigating the pathological mechanisms and therapeutic strategies of AD.
