Abstract
Toxocara canis is a globally distributed zoonotic parasite. The parasite has recently become a concern for public health in Vietnam. This cross-sectional study aimed to identify and quantify the risk factors associated with T. canis infection in dogs in Dak Lak province in the Central Highlands of Vietnam. The risk factors were identified using a mixed-effects logistic regression model and quantified using population attributable fractions. Examination of fecal samples collected from 1455 dogs using the sodium nitrate flotation technique showed 37.32% (95% CI: 34.83-39.86) of dogs infected with T. canis. The factors, including study location, multiple dogs living in a household, dog age, dog breed, and places keeping dogs were associated with a dog's likelihood of being T. canis infection. The household and individual dog levels contributed 17% and 82%, respectively, to the prevalence of T. canis in dogs. The adjusted population attributable fraction for confining dogs and raising an individual dog per household was 52% and 27%, respectively. The result of this study indicated that to minimize the burden of T. canis, intervention measures should target individual dogs and household levels.

[PMID: 36211451 PMCID: PMC9533023 DOI: 10.3389/fcell.2022.946566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2022] [Accepted: 08/26/2022] [Indexed: 11/13/2022] Open
Abstract
Background: There has been emerging evidence that liver sinusoidal endothelial cells (LSECs) play an important role in the pathogenesis of nonalcoholic steatohepatitis (NASH). This study aims to figure out the signature of the gene expression profile of LSECs in NASH and to explore potential biomarkers related to damaged LSECs in NASH.Methods and materials: Animal experiments were performed to demonstrate the significant structural damage of LSECs in the NASH model. To further understand the functional changes of these damaged LSECs in NASH, we used the public GEO database that contained microarray data for the gene expression of LSECs in NASH and normal mouse liver. Differentially expressed genes (DEGs) were analyzed, and further Gene Ontology (GO) enrichment analysis was performed to understand the functional changes. The hub genes were then identified and validated via external GEO databases.Results: There was significant structural damage to LSECs in the NASH model, accompanied by remarkable functional changes of LSECs with 174 DEGs (156 upregulated and 18 downregulated genes). The functions of these DEGs were mainly enriched in the inflammatory reactions and immune responses. Nine specifically expressed hub genes were identified. Among them, CCL4 and ITGAX showed the most significant correlation with NASH, with AUROC of 0.77 and 0.86, respectively. The protein–protein interaction network, mRNA–miRNA interaction network, and ceRNA network were further predicted.Conclusion: LSECs show significant structural damage and functional changes in NASH. The LSEC-related DEGs, such as CCL4 and ITGAX, might be promising biomarkers as well as potential treatment targets for NASH.
