A Subunit Vaccine Harboring the Fusion Capsid Proteins of Porcine Circovirus Types 2, 3, and 4 Induces Protective Immune Responses in a Mouse Model.

Coinfections with porcine circovirus types 2, 3, and 4 (PCV2, PCV3, and PCV4) are increasingly being detected in the swine industry. However, there is no commercially available vaccine which prevents coinfection with PCV2, PCV3, and PCV4. The development of a vaccine expressing capsid (Cap) fusion proteins of multiple PCVs represents a promising approach for broadly preventing infection with PCVs.

The PCV3 Cap Virus-like Particle Vaccine with the Chimeric PCV2-Neutralizing Epitope Gene Is Effective in Mice.

Porcine circovirus type 3 (PCV3) infection can cause symptoms similar to those of porcine circovirus type 2 (PCV2) infection, and coinfections with both PCV2 and PCV3 are observed in the swine industry. Consequently, developing chimeric vaccines is essential to prevent and control porcine circovirus infections. In this study, we used both and mammalian expression systems to express PCV3 Cap (Cap3) and a chimeric gene containing the PCV2-neutralizing epitope within the PCV3 Cap (Cap3-Cap2E), which were assembled into virus-like particle (VLP) vaccines.

SRSF2 plays an unexpected role as reader of mC on mRNA, linking epitranscriptomics to cancer.

A common mRNA modification is 5-methylcytosine (mC), whose role in gene-transcript processing and cancer remains unclear. Here, we identify serine/arginine-rich splicing factor 2 (SRSF2) as a reader of mC and impaired SRSF2 mC binding as a potential contributor to leukemogenesis. Structurally, we identify residues involved in mC recognition and the impact of the prevalent leukemia-associated mutation SRSF2.

A novel brick for bispecific antibody construction.

In recent years, the development of bispecific antibodies (bsAbs) has become a major trend in the biopharmaceutical industry. By simultaneously engaging two molecular targets, bsAbs have exhibited unique mechanisms of action that could lead to clinical benefits unattainable by conventional monoclonal antibodies. The type of structure used to construct a bsAb directly influences the distance, angle, degree of freedom, and affinity between the two antibody binding sites and the interaction between the two antigens or the cells where the antigens are located, which have been bound by the antibody.

Mitigation Effects of Selenium Nanoparticles on Depression-Like Behavior Induced by Fluoride in Mice via the JAK2-STAT3 Pathway.

Depression is a mental health problem with typically high levels of distress and dysfunction, and 150 mg/L fluoride (F) can induce depression-like behavior. The development of depression is correlated with neuronal atrophy, insufficient secretion of monoamine neurotransmitters, extreme deviations from the normal microglial activation status, and immune-inflammatory response. Studies found that Se supplementation was related to the improvement of depression.

Serological evidence of bovine viral diarrhea virus and peste des petits ruminants virus infection in alpacas (Vicugna pacos) in Shanxi Province, northern China.

Bovine viral diarrhea virus (BVDV) and peste des petits ruminants virus (PPRV) are two important pathogens associated with a variety of disease syndromes that result in substantial financial losses in animal husbandry. This study was performed to assess the seroprevalence of antibodies to BVDV and PPRV among alpacas raised in Shanxi Province of northern China. Serum samples were obtained from 246 alpacas in Taiyuan (n=182), Xinzhou (n=31), and Jinzhong cities (n=33) of Shanxi Province, and serological testing was carried out using the competitive enzyme-linked immunosorbent assay.

A highly CMOS compatible hafnia-based ferroelectric diode.

Memory devices with high speed and high density are highly desired to address the 'memory wall' issue. Here we demonstrated a highly scalable, three-dimensional stackable ferroelectric diode, with its rectifying polarity modulated by the polarization reversal of HfZrO films. By visualizing the hafnium/zirconium lattice order and oxygen lattice order with atomic-resolution spherical aberration-corrected STEM, we revealed the correlation between the spontaneous polarization of HfZrO film and the displacement of oxygen atom, thus unambiguously identified the non-centrosymmetric Pca2 orthorhombic phase in HfZrO film.

Expression and immunoreactivity of a recombinant multi-epitope antigen designed based on four major structural proteins of avian infectious bronchitis virus.

The development of rapid, simple, and sensitive diagnostic methods for identification of avian infectious bronchitis virus (IBV) is crucial for the effective control of avian infectious bronchitis. In the present study, a tandemly arranged multiepitope peptide (named SEMN) was designed with four antigenic regions derived from four major structural proteins of IBV. Then, we performed codon optimization of SEMN gene by changing the codon-adaptation index from 0.

Calcium relieves fluoride-induced bone damage through the PI3K/AKT pathway.

Bone is the main target of fluorosis, and it has been perfectly elaborated that a moderate dosage of calcium (Ca) can alleviate bone fluorosis. However, whether Ca can alleviate fluorosis through the phosphatidylinositol 3 kinase (PI3K)/protein kinase B (AKT) signaling pathway has not yet been reported. Hence, we evaluated the histopathological structure, the imbalance of the biochemical index of bone metabolism, and the expression levels of PI3K/AKT apoptosis signaling pathway-related genes in rats treated with sodium fluoride (NaF, F) and/or calcium carbonate (CaCO3) for 120 days.

5-Methylcytosine Analysis by RNA-BisSeq.

5-Methylcytosine (mC) is a posttranscriptional RNA modification identified in both stable and highly abundant tRNAs and rRNAs, and in mRNAs. Many known or novel mC sites have been validated by using advanced high-throughput techniques combined with next-generation sequencing (NGS), especially RNA bisulfite sequencing (RNA-BisSeq). Here we introduce an optimized RNA-BisSeq method by using ACT random hexamers to prime the reverse transcription of bisulfite-treated RNA samples to detect the mC sites.

Transcripts of antibacterial peptides in chicken erythrocytes infected with Marek's disease virus.

Background: Chicken erythrocytes are involved in immunity through binding of toll-like receptors (TLRs) with their ligands to activate downstream signaling and lead to cytokine production in erythrocytes. Some avian β-defensins (AvBDs) are constitutively expressed in tissues and some others can be induced by various bacteria and viruses. However, the expression of AvBDs in erythrocytes has not yet been studied extensively.
