Unconventional IFNω-like Genes Dominate the Type I IFN Locus and the Constitutive Antiviral Responses in Bats.

Bats are the natural reservoir hosts of some viruses, some of which may spill over to humans and cause global-scale pandemics. Different from humans, bats may coexist with high pathogenic viruses without showing symptoms of diseases. As one of the most important first defenses, bat type I IFNs (IFN-Is) were thought to play a role during this virus coexistence and thus were studied in recent years.

N-linked glycoproteins and host proteases are involved in swine acute diarrhea syndrome coronavirus entry.

Gaining insight into the cell-entry mechanisms of swine acute diarrhea syndrome coronavirus (SADS-CoV) is critical for investigating potential cross-species infections. Here, we demonstrated that pretreatment of host cells with tunicamycin decreased SADS-CoV attachment efficiency, indicating that N-linked glycosylation of host cells was involved in SADS-CoV entry. Common N-linked sugars Neu5Gc and Neu5Ac did not interact with the SADS-CoV S1 protein, suggesting that these molecules were not involved in SADS-CoV entry.

Identification of TMEM53 as a novel SADS-CoV restriction factor that targets viral RNA-dependent RNA polymerase.

Zoonotic transmission of coronaviruses (CoVs) poses a serious public health threat. Swine acute diarrhea syndrome coronavirus (SADS-CoV), originating from a bat HKU2-related CoV, causes devastating swine diseases and poses a high risk of spillover to humans. Currently, licensed therapeutics that can prevent potential human outbreaks are unavailable.

Psychiatric Nurses' Knowledge and Practice Barriers to Administering Long-Acting Injectable (LAI) Antipsychotics in Taiwan: A Mixed-Methods Study.

Long-acting antipsychotic injections require that psychiatric nurses choose the proper injection site and technique to avoid harming patients. This research conducted a mixed-method study to examine the long-acting injectable antipsychotic (LAI) knowledge, practice, and administrative barriers in a sample of 269 psychiatric nurses from 3 public psychiatric hospitals in Taiwan. Self-report questionnaires showed female nurses exhibiting higher scores and older nurses demonstrating more knowledge.

Strategy To Assess Zoonotic Potential Reveals Low Risk Posed by SARS-Related Coronaviruses from Bat and Pangolin.

In the last 2 decades, pathogens originating in animals may have triggered three coronavirus pandemics, including the coronavirus disease 2019 pandemic. Thus, evaluation of the spillover risk of animal severe acute respiratory syndrome (SARS)-related coronavirus (SARSr-CoV) is important in the context of future disease preparedness. However, there is no analytical framework to assess the spillover risk of SARSr-CoVs, which cannot be determined by sequence analysis alone.

[Research methods and progress on the reduction effects of vehicle emission pollutants by street canyon greening.].

With the development of high-density and high-rise buildings on both sides of the street, widespread attention has been paid to the applicability of the traditional greening model of 'the more trees, the better atmospheric environment' in dealing with air pollution in urban street canyons. Clarifying the characteristics of street canyons greening and its planting design pattern on the reduction of emission pollutants by vehicles is an important prerequisite for the improvement of air quality in the street canyons. Based on literature review, we compared the applicability and limitations of the three methods, including field observation, wind tunnel test, and numerical simulation.

Mental Health Nurses' Tacit Knowledge of Strategies for Improving Medication Adherence for Schizophrenia: A Qualitative Study.

Non-adherence to medication among patients with schizophrenia is an important clinical issue with very complex reasons. Since medication administration is an essential nursing responsibility, improving strategies for patient medication compliance must be fully understood. This study aimed to explore the strategies mental health nurses (MHNs) implement in clinically improving patients with schizophrenia and to describe the nurses' tacit knowledge of application strategies.

Effects of Rehabilitation Models on Self-Stigma among Persons with Mental Illness.

Social stigma is inevitable for mentally ill patients, but how patients treat themselves is a priority for rehabilitation and an important buffer mechanism. This study thus aimed to measure the effectiveness of rehabilitation models for improving self-stigma. This quasi-experimental research design applied purposeful sampling.

Characterizing the role of Tupaia DNA damage inducible transcript 3 (DDIT3) gene in viral infections.

DNA damage inducible transcript 3 (DDIT3, also known as CHOP) belongs to the CCAAT/enhancer-binding protein (C/EBP) family and plays an essential role in endoplasmic reticulum stress. Here, we characterized the potential role of the Chinese tree shrew (Tupaia belangeri chinensis) DDIT3 (tDDIT3) in viral infections. The tDDIT3 protein is highly conserved and has a species-specific insertion of the SQSS repeat upstream of the C-terminal basic-leucine zipper (bZIP) domain.

GBP1 Interacts with STING to Initiate Autophagy and Restrict Herpes Simplex Virus Type 1 Infection.

Stimulator of IFN genes (STING) is a key molecule that binds to cyclic dinucleotides produced by the cyclic GMP-AMP synthase to activate IFN expression and autophagy in the fight against microbial infection. The regulation of STING in the activation of IFN expression has been extensively reported, whereas the regulation of STING in the initiation of autophagy is still insufficiently determined. IFN-inducible guanylate-binding proteins (GBPs) are central to the cell-autonomous immunity in defending a host against viral, bacterial, and protozoan infections.

Identification of ZDHHC17 as a Potential Drug Target for Swine Acute Diarrhea Syndrome Coronavirus Infection.

The recent emergence and spread of zoonotic viruses highlights that animal-sourced viruses are the biggest threat to global public health. Swine acute diarrhea syndrome coronavirus (SADS-CoV) is an HKU2-related bat coronavirus that was spilled over from bats to swine, causing large-scale outbreaks of severe diarrhea disease in piglets in China. Unlike other porcine coronaviruses, SADS-CoV possesses broad species tissue tropism, including primary human cells, implying a significant risk of cross-species spillover.

Tupaia guanylate-binding protein 1 interacts with vesicular stomatitis virus phosphoprotein and represses primary transcription of the viral genome.

Chinese tree shrews (Tupaia belangeri chinensis) are increasingly used as an alternative experimental animal to non-human primates in studying viral infections. Guanylate-binding proteins (GBP) belong to interferon (IFN)-inducible GTPases and defend the mammalian cell interior against diverse invasive pathogens. Previously, we identified five tree shrew GBP genes (tGBP1, tGBP2, tGBP4, tGBP5, and tGBP7) and found that tGBP1 showed antiviral activity against vesicular stomatitis virus (VSV) and type 1 herpes simplex virus (HSV-1) infections.

OASL1 Promotes Cellular Antiviral Immune Responses by Recruiting MDA5 to MAVS.

Melanoma differentiation-associated gene 5 (MDA5) is a key cytoplasmic dsRNA sensor. Upon binding to invading viral RNA, activated MDA5 is recruited to mitochondria and interacts with mitochondrial antiviral signaling gene (MAVS) to initiate innate antiviral immune responses. The elegant regulation of this process remains elusive.

MAVS Is a Dual Target during Hepatitis C Virus Infection for Innate Immune Evasion and Viral Replication via NF-κB.

Hepatitis C virus (HCV) infection is the cause of severe liver disease in many people. The restricted species tropism of HCV hinders the research and development of drugs and vaccines. The Chinese tree shrew () is a close relative of primates and can be infected by HCV, but the underlying mechanisms are unknown.

COVID-19-like symptoms observed in Chinese tree shrews infected with SARS-CoV-2.

The coronavirus disease 2019 (COVID-19) pandemic continues to pose a global threat to the human population. Identifying animal species susceptible to infection with the SARS-CoV-2/ HCoV-19 pathogen is essential for controlling the outbreak and for testing valid prophylactics or therapeutics based on animal model studies. Here, different aged Chinese tree shrews (adult group, 1 year old; old group, 5-6 years old), which are close relatives to primates, were infected with SARS-CoV-2.

An Alternative Splicing of STING Modulated Anti-RNA Virus Responses by Targeting MDA5-LGP2 and IRF3.

The stimulator of IFN genes (STING; also known as MITA, TMEM173, MPYS, or ERIS) is generally regarded as a key adaptor protein for sensing pathogenic DNA genomes. However, its role in RNA viral signaling as part of the innate immunity system remains controversial. In this study, we identified two isoforms of STING (a full-length STING [tSTING-FL] and a STING short isoform [tSTING-mini]) in the Chinese tree shrew (), a close relative of primates.

Chromosomal level assembly and population sequencing of the Chinese tree shrew genome.

Chinese tree shrews () have become an increasingly important experimental animal in biomedical research due to their close relationship to primates. An accurately sequenced and assembled genome is essential for understanding the genetic features and biology of this animal. In this study, we used long-read single-molecule sequencing and high-throughput chromosome conformation capture (Hi-C) technology to obtain a high-qualitychromosome-scale scaffolding of the Chinese tree shrew genome.

Molecular identification and antiviral function of the guanylate-binding protein (GBP) genes in the Chinese tree shrew (Tupaia belangeri chinesis).

Following viral detection and interferons (IFNs) production, several hundreds of IFN-stimulated genes (ISGs) are subsequently induced to act as direct antiviral effectors or regulators of the IFN signaling. The guanylate-binding protein (GBP) family belongs to IFN-inducible GTPases defending the host against a diverse group of invading pathogens such as parasites, bacteria and viruses. The Chinese tree shrew (Tupaia belangeri chinese) has been increasingly used as an alternative experimental animal to primates in studying viral infectious diseases.

Establishment and characterization of an immortalized renal cell line of the Chinese tree shrew (Tupaia belangeri chinesis).

The Chinese tree shrew holds a great potential as a viable animal model in biomedical research, especially for infectious diseases and neuropsychiatric disorders. A thorough understanding of the innate immunity, which represents the first line that defends the host against viral infection, of the Chinese tree shrew, is needed. However, the progress is hindered by the lack of a proper cell line for research usage.

Molecular characterization of the 2',5'-oligoadenylate synthetase family in the Chinese tree shrew (Tupaia belangeri chinensis).

Virus infection induces type I interferons (IFNs) that in turn exert their pleiotropic effects through inducing a large number of interferon-stimulated genes (ISGs). The IFN-induced 2',5'-oligoadenylate synthetases (OASs) have been identified as a member of the ISGs family characterized by the ability to synthesize 2',5'-oligoadenylate (2-5A), which can induce the degradation of viral RNA by activating RNase L within the infected cells to block viral replications. In this study, we characterized the OASs of the Chinese tree shrew (Tupaia belangeri chinensis), a small mammal genetically close to primates and has the potential as animal model for viral infections.
