Cancer Med 2023; 12:4938-4950. [PMID: 36062845 PMCID: PMC9972111 DOI: 10.1002/cam4.5186] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Revised: 07/05/2022] [Accepted: 08/14/2022] [Indexed: 12/24/2022] Open
Abstract
Despite great advance has been made in multi-modality treatments for HCC patients, the effectiveness is far from satisfactory with worse survival outcome, which may be partly explainable by the anti-tumor deficiency of the immune system. It is necessary to clarify the molecular mechanism of HCC immunodeficiency. Here, we demonstrated that carbohydrate sulfotransferase 11 (CHST11) was upregulated in HCC and related to advanced TNM stage. HCC patients with TP53 mutation showed higher CHST11 expression. Survival analysis revealed that CHST11 was an independent prognostic biomarker in HCC. Cellular functional experiments indicated that knockdown of CHST11 in HCC inhibited cell proliferation and metastasis. Gene functional enrichment analyses indicated that CHST11 modulated pathways related to tumor growth, metastasis and immune regulation. Continuative immune-related analyses revealed that CHST11 expression facilitated Tregs infiltration in HCC and promoted the expression of checkpoints PD-L1/PD-1, resulting in the immunosuppression of HCC. Targeting CHST11 may inhibit Tregs infiltration and enhance the antineoplastic effect of immune checkpoint inhibitors, which provides a novel insight into the combination immunotherapy with Treg-modulating agents and PD-L1/PD-1 inhibitors.

Gorbunov SG, Mazankova LN, Os’kin AN. The role of TLR-3 in the course and outcomes of rotavirus infection in infants. CHILDREN INFECTIONS 2022. [DOI: 10.22627/2072-8107-2022-21-3-5-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 04/04/2023]
Abstract
It was found that the clinical picture of rotavirus infection in infants with an initially low number of immunocompetent cells expressing TLR-3 does not differ significantly from that of patients with an initially large number of cells expressing TLR-3. When analyzing the treatment, it turned out that antibacterial therapy due to the activation of bacterial microflora was used only in children with an initially low number of immunocompetent cells expressing TLR-3. In the same group of patients, the development of atopic dermatitis and food allergies was noted during catamnestic observation for 6—12 months after rotavirus infection.

T-Cell Responses after Rotavirus Infection or Vaccination in Children: A Systematic Review. Viruses 2022; 14:v14030459. [PMID: 35336866 PMCID: PMC8951614 DOI: 10.3390/v14030459] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2022] [Revised: 02/14/2022] [Accepted: 02/16/2022] [Indexed: 02/04/2023] Open
Abstract
Cellular immunity against rotavirus in children is incompletely understood. This review describes the current understanding of T-cell immunity to rotavirus in children. A systematic literature search was conducted in Embase, MEDLINE, Web of Science, and Global Health databases using a combination of “t-cell”, “rotavirus” and “child” keywords to extract data from relevant articles published from January 1973 to March 2020. Only seventeen articles were identified. Rotavirus-specific T-cell immunity in children develops and broadens reactivity with increasing age. Whilst occurring in close association with antibody responses, T-cell responses are more transient but can occur in absence of detectable antibody responses. Rotavirus-induced T-cell immunity is largely of the gut homing phenotype and predominantly involves Th1 and cytotoxic subsets that may be influenced by IL-10 Tregs. However, rotavirus-specific T-cell responses in children are generally of low frequencies in peripheral blood and are limited in comparison to other infecting pathogens and in adults. The available research reviewed here characterizes the T-cell immune response in children. There is a need for further research investigating the protective associations of rotavirus-specific T-cell responses against infection or vaccination and the standardization of rotavirus-specific T-cells assays in children.

Abstract
OBJECTIVE To investigate clinical effect of probiotics combined with zinc and selenium preparation in the treatment of child rotavirus enteritis. METHODS In this retrospective study, the patients were divided into two groups based on treatment method. The control group (n=42) received probiotic therapy, while the experimental group (n=43) received probiotics combined with zinc and selenium preparation. Clinical efficacy, stool frequency and incidence of adverse reactions after treatment were compared to assess the clinical effect. RESULTS The clinical effect was improved after intervention (P<0.05), and the total effective rate of two groups was 88.4% (38/43), 50% (21/42), respectively. Time to symptom disappearance was significantly decreased in the experimental group as compared to the control group. The myocardial zymogram indices (CK, CK-MB and AST) were decreased after treatment, and the levels in the experimental group were significantly lower than in the control group (P<0.05). Moreover, we observed that the levels of inflammatory factors (IL-6, IL-8 and hsCRP) in the experimental group were significantly lower than those of the control group after intervention (all P<0.05). CONCLUSION Probiotics combined with zinc and selenium preparation can not only significantly improve the clinical effect, but also shorten the course of disease.

Baicalin Is Curative Against Rotavirus Damp Heat Diarrhea by Tuning Colonic Mucosal Barrier and Lung Immune Function. Dig Dis Sci 2020; 65:2234-2245. [PMID: 31802384 DOI: 10.1007/s10620-019-05977-w] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Accepted: 11/27/2019] [Indexed: 12/22/2022]
Abstract
BACKGROUND Previous studies have indicated that rotavirus (RV) is a causative factor for diarrhea and gastroenteritis in pediatric and neonatal settings. Baicalin has many functions, including antibacterial, antiinflammatory, and antihypertensive activities. However, the immunological mechanism of RV-induced diarrhea with heat-dampness syndrome (RV-DH) remains unclear. AIMS The aim of this study is to explore the role of baicalin in RV-DH diarrhea and its underlying mechanism. METHODS A mouse model of pediatric RV-DH diarrhea was established and treated with baicalin. The concentrations of cytokines were detected by enzyme-linked immunosorbent assay. Messenger RNA (mRNA) expression levels were detected by quantitative real-time polymerase chain reaction (qRT-PCR), while protein expression levels were determined by Western blotting and immunohistochemistry. Flow cytometry was used to detect the frequency of lymphocytes. RESULTS The concentrations of interleukin-1β (IL-1β), IL-2, IL-6, IL-8, RVvb, and secretory immunoglobulin A (SIgA) in bronchoalveolar lavage fluid (BALF) and colonic mucosa were significantly increased in the RV-DH group. Decreased expression of occludin, claudin-1, and zonula occludens-1 (ZO-1) indicated loss of tight junction function and disturbances in intestinal mucosal permeability in the RV-DH group. Flow cytometry analysis showed a high rate of CD8+ lymphocytes and low amount of CD4+ lymphocytes in the RV-DH group. Treatment of RV-DH mice with baicalin significantly reduced the duration of diarrhea and ameliorated the symptoms and pathological and immunological changes. Furthermore, baicalin inhibited STAT1 and activated STAT3 signaling pathways. CONCLUSIONS These findings indicate the curative and immunoregulatory properties of baicalin and have direct practical and clinical relevance for the treatment of RV-DH enteritis in humans.

Abstract
Biliary atresia (BA) is a childhood disease which manifests with abnormal narrowing, blockage or complete absence of bile ducts within the liver. Many possible etiologies have been reported for the development of BA, including congenital, perinatal and acquired conditions. Since the 1970's, there has been increasing evidence linking BA development to viral perinatal infections. The viral vectors most commonly implicated include members of the herpesviridae family (cytomegalovirus and Epstein-Barr virus) as well as those of the reoviridae family (reovirus and rotavirus). While extensive work has been done on a murine model of disease, the current review focuses primarily on evidence from human studies of viral vectors in children afflicted with BA.

Abstract
Rotavirus (RV) infection causes acute, watery dehydrating diarrhea and even death in infants and other young animals, resulting in a severe economic burden; however, little is known about the innate immune mechanisms associated with RV infection. Dendritic cells (DCs), which are professional antigen-presenting cells (APCs), serve as a bridge connecting the innate and adaptive immune system. In this study, the interaction between murine bone marrow-derived DCs (BMDCs) and porcine rotavirus (PRV) was investigated in vitro. Upon stimulation, the expression levels of MHC-II, CD40, CD80, CD86 and CD83 in BMDCs increased in a time-dependent manner, indicating activation and maturation by PRV. In addition, up-regulated Toll-like receptor 2 (TLR2), TLR3 and NF-κB increased the production of interleukin-12 and interferon-γ. The PRV-stimulated BMDCs also showed increased stimulatory capacity in mixed lymphocyte reactions and promoted the Th1 subtype response.
