Upregulation of CD244 promotes CD8 T cell exhaustion in patients with alveolar echinococcosis and a murine model.

Background: In patients with alveolar echinococcosis (AE), CD8 T cells undergo functional exhaustion, which accelerates the malignant progression of AE. However, the role of inhibitory receptor CD244 in mediating CD8 T cell exhaustion remains elusive.

Methods: CD244 expression on exhausted CD8 T cells in the close liver tissue (CLT) of AE patients was analyzed using single-cell RNA sequencing data.

Targeting myeloid-derived suppressor cells promotes antiparasitic T-cell immunity and enhances the efficacy of PD-1 blockade (15 words).

Immune exhaustion corresponds to a loss of effector function of T cells that associates with cancer or chronic infection. Here, our objective was to decipher the mechanisms involved in the immune suppression of myeloid-derived suppressor cells (MDSCs) and to explore the potential to target these cells for immunotherapy to enhance checkpoint blockade efficacy in a chronic parasite infection. We demonstrated that programmed cell-death-1 (PD-1) expression was significantly upregulated and associated with T-cell dysfunction in advanced alveolar echinococcosis (AE) patients and in Echinococcus multilocularis-infected mice.

Immunological Characteristics of Hepatic Dendritic Cells in Patients and Mouse Model with Liver Infection.

The cestode which mainly dwells in the liver, leads to a serious parasitic liver disease called alveolar echinococcosis (AE). Despite the increased attention drawn to the immunosuppressive microenvironment formed by hepatic AE tissue, the immunological characteristics of hepatic dendritic cells (DCs) in the AE liver microenvironment have not been fully elucidated. Here, we profiled the immunophenotypic characteristics of hepatic DC subsets in both clinical AE patients and a mouse model.

Upregulation of LAG3 modulates the immune imbalance of CD4+ T-cell subsets and exacerbates disease progression in patients with alveolar echinococcosis and a mouse model.

Infection with the cestode Echinococcus multilocularis (E. multilocularis) causes alveolar echinococcosis (AE), a tumor-like disease predominantly affecting the liver but able to spread to any organ. T cells develop functional defects during chronic E.

Characterization of a Novel Fe Activated Non-Blue Laccase from .

Herein, a novel laccase gene, , was amplified from and successfully expressed in with a molecular weight of approximately 50 kDa. The purified Melac13220 had no absorption peak at 610 nm and remained silent within electron paramagnetic resonance spectra, suggesting that Melac13220 belongs to the non-blue laccase group. Both inductively coupled plasma spectroscopy/optical emission spectrometry (ICP-OES) and isothermal titration calorimetry (ITC) indicated that one molecule of Melac13220 can interact with two iron ions.

: The establishment of the metacestode in the liver is associated with control of the CD4 T-cell-mediated immune response in patients with cystic echinococcosis and a mouse model.

The larval stage of the tapeworm () caused a chronic infection, known as cystic echinococcosis (CE), which is a worldwide public health problem. The human secondary CE is caused by the dissemination of protoscoleces (PSCs) when fertile cysts are accidentally ruptured, followed by development of PSCs into new metacestodes. The local immune mechanisms responsible for the establishment and established phases after infection with .

Effects of Message Framing on Cancer Prevention and Detection Behaviors, Intentions, and Attitudes: Systematic Review and Meta-analysis.

Background: With the increasing health care burden of cancer, public health organizations are increasingly emphasizing the importance of calling people to engage in long-term prevention and periodical detection. How to best deliver behavioral recommendations and health outcomes in messaging is an important issue.

Objective: This study aims to disaggregate the effects of gain-framed and loss-framed messages on cancer prevention and detection behaviors and intentions and attitudes, which has the potential to inform cancer control programs.

[Trajectory modeling for estimating the trend of human papillomavirus infection status among men who have sex with men].

Objective: To investigate whether trajectory model can be used to explore the trend of anal human papillomavirus (HPV) infection status among HIV-negative men who have sex with men (MSM).

Methods: HIV-negative MSM were recruited by using the "snowball" method from 1st September 2016 to 30th September 2017 in Urumqi. The subjects were followed-up every six months since enrollment.

[Association between copy number variations and risk of overweight/obesity among Han, Uyghur, and Kazak children].

Objective: To study the association between the prevalence of overweight/obesity and copy number variations (CNVs) among Han, Uyghur, and Kazak children in Xinjiang, China.

Methods: The kindergartens in Ili, Altay, and Karamay in Xinjiang were selected as research sites, and stratified cluster sampling was used to select the children aged 3-7 years. Body height and body weight were measured, and exfoliated buccal mucosa cells were collected.

Prevalence and risk factors of anal human papillomavirus infection among HIV-negative men who have sex with men in Urumqi city of Xinjiang Uyghur Autonomous Region, China.

Background: Infection with human papillomavirus (HPV) is the most common sexually transmitted infection among men who have sex with men (MSM). Study on prevalence and risk factors of anal HPV infection among HIV-negative MSM in Northwestern China was rare.

Methods: We performed a cross-sectional study of HPV prevalence using anal swab specimens among HIV-negative MSM in Urumqi city of Xinjiang Uyghur Autonomous Region, China between April 1st and October 30th in 2016.

[Comparison of human papilloma virus infection status between men who have sex with men recruited from gay bathhouses and HIV voluntary counseling and testing clinics respectively in Urumqi].

To understand the human papilloma virus (HPV) infection status in men who have sex with men (MSM) recruited from gay bathhouses and HIV voluntary counseling and testing (VCT) clinics in Urumqi, Xinjiang Uygur autonomous region, and identify the associated risk factors. A total of 200 MSM aged ≥18 years were recruited by using the " snowballing" sampling method from gay bathhouses and VCT clinics in Urumqi during March-May, 2016. The MSM recruited completed questionnaires after filling in the informed consent form.

[HIV infection and associated factors in men who have sex with men and also with women in Urumqi from 2010 to 2014].

To understand the demographic characteristics, sexual behaviors and the factors associated with HIV infection in men who have sex with men and also with women (MSMW) in Urumqi. According to the "National AIDS Sentinel Surveillance Protocol" , the data of MSM's demographic characteristics, sex behavior histories and serological detection results were collected through Urumqi AIDS sentinel surveillance system during 2010-2014. In MSM, those also had heterosexual behaviors were considered as MSMW.
