Intestinal epithelial cells (IECs) are an important component of the intestinal barrier. In previous studies, we have demonstrated that suppressing microRNA-222-3p (miR-222-3p) can protect against oxidative stress in IECs, which ameliorates colonic injuries in UC mice and prevents the conversion of UC to CAC. In this case, we hope to explore whether moxibustion can alleviate UC and CAC by inhibiting miR-222-3p based on mouse models of UC and CAC. After herb-partitioned moxibustion (HPM) intervention, the disease activity index (DAI) and colon macroscopic damage index (CMDI) were significantly reduced in UC mice, and the number and volume of intestinal tumors were decreased considerably in CAC mice. Meanwhile, we found that HPM suppressed miR-222-3p expression and upregulated the mRNA and protein expression of Brahma-related gene 1 (BRG1), nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase-1 (HO-1), while inhibiting Kelch-like ECH-associated protein 1 (Keap1) expression in IECs of UC and CAC mice. With changes in reactive oxygen species (ROS), malondialdehyde (MDA), glutathione peroxidase (GSH-Px), and inflammatory cytokines interleukin (IL)-1<i>β</i> and tumor necrosis factor (TNF)-<i>α</i>), we verified that HPM protects against oxidative stress and inflammation in IECs of UC and CAC mice. The effect of HPM was inhibited in miR-222-3p overexpression mice, further demonstrating that the protective effect of HPM on UC and CAC mice was through inhibiting miR-222-3p.

The current work was aimed at studying the specific humoral responses against SARS-CoV-2 in Cuban COVID-19 convalescents. We developed suitable tools and methods based on ELISA methodology, for supporting this evaluation. Here, we describe the development of an ELISA for the quantification of anti-RBD IgG titers in a large number of samples and a similar test in the presence of NH₄SCN as chaotropic agent for estimating the RBD specific antibody avidity. Additionally, a simple and rapid ELISA based on antibody-mediated blockage of the binding RBD-ACE2 was implemented for detecting, as a surrogate of conventional test, the levels of anti-RBD inhibitory antibodies in convalescent sera. In a cohort of 273 unvaccinated convalescents, we identified higher anti-RBD IgG titer (1 : 1,330, <i>p</i>  < 0.0001) and higher levels of inhibitory antibodies blocking RBD-ACE2 binding (1 : 216, <i>p</i>  < 0.05) among those who had recovered from severe illness. Our results suggest that disease severity, and not demographic features such as age, sex, and skin color, is the main determinant of the magnitude and neutralizing ability of the anti-RBD antibody response. An additional paired longitudinal assessment in 14 symptomatic convalescents revealed a decline in the antiviral antibody response and the persistence of neutralizing antibodies for at least 4 months after the onset of symptoms.

To date, there have been no pan-cancer studies of HNRNPA2B1, particularly within the TME. Therefore, we conducted a pan-cancer analysis of HNRNPA2B1 using TCGA data. Based on datasets from TCGA, TARGET, Genotype-Tissue Expression, and Human Protein Atlas, we employed a range of bioinformatics approaches to explore the potential oncogenic role of HNRNPA2B1. This included analyzing the association of HNRNPA2B1 expression with prognosis, tumor mutation burden (TMB), microsatellite instability (MSI), immune response, and immune cell infiltration of individual tumors. We further validated the bioinformatic findings using immunohistochemistry techniques. HNRNPA2B1 was found to be differentially expressed across most tumor types in TCGA's pan-cancer database and was predictive of poorer clinical staging and survival status. HNRNPA2B1 expression was also closely linked to TMB, MSI, tumor stemness, and chemotherapy response. HNRNPA2B1 plays a significant role in the TME and is involved in the regulation of novel immunotherapies. Its expression is significantly associated with the infiltration of macrophages, dendritic cells, NK cells, and T cells. Furthermore, HNRNPA2B1 is closely associated with immune checkpoints, immune-stimulatory genes, immune-inhibitory genes, MHC genes, chemokines, and chemokine receptors. We performed a comprehensive evaluation of HNRNPA2B1, revealing its potential role as a prognostic indicator for patients and its immunomodulatory functions.","PeriodicalId":15952,"journal":{"name":"Journal of Immunology Research","volume":"74 1","pages":"5515307"},"PeriodicalIF":4.1,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142261067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
