Neonatal Bacillus Calmette-Guérin (BCG) vaccination results in a positive effect on hippocampal neurogenesis and cognition. Serum cytokines are considered to be the chief culprit. In this study, serum from BCG-treated mice was identified as Th1 polarized serum. The serum showed an increased ratio of IFN-γ to IL-4 and decreased levels of TNF-α and IL-6. After Th1 polarized serum was injected intraperitoneally into postnatal mice, the levels of cytokines and ratio of IFN-γ to IL-4 in the serum and hippocampus of postnatal mice showed a similar alteration as those in Th1 polarized serum...

Peroxisome proliferator-activated receptor gamma (PPARγ) and miR-124 have been reported to play important roles in regulation of inflammation. However, the underlying anti-inflammatory mechanisms remain not well understood. In the present study, we demonstrated that the expression level of PPARγ is positively correlated with that of miR-124 in patients with sepsis. Activation of PPARγ upregulates miR-124 and in turn inhibits miR-124 target gene. PPARγ bound directly to PPRE in the miR-124 promoter region, and enhanced the promoter transcriptional activity...

The conjugation of small ubiquitin-like modifier (SUMO) to the target protein, namely, SUMOylation, is involved in the regulation of many important biological events including host-pathogen interaction. Some viruses have evolved to exploit the host SUMOylation machinery to modify their own protein. Retroviral Gag protein plays critical roles in the viral life cycle. The HIV-1 p6 and the Moloney murine leukemia virus CA have been reported to be conjugated with SUMO. In this study, we report for the first time, to our knowledge, the covalent conjugation of equine infectious anemia virus (EIAV) Gag with SUMO...

Type I IFNs play crucial roles in antiviral immune responses. By inducing cellular resistance to viral infection and apoptosis of virus-infected cells, they impair virus replication and eliminate the invading pathogens. However, in CHB patients, generation of type I IFN was significantly impaired and the underlying mechanisms have not been fully understood. MicroRNA-548 family has been implicated in regulating antiviral response upon various infections. Here we explored the potential role of miR-548j in modulating type I IFN production in CHB...

BACKGROUND: Diets low in fermentable oligosaccharides, disaccharides, monosaccharides, and polyols (FODMAPS) are used to manage symptoms in individuals with irritable bowel syndrome. Although effective at reducing symptoms, the diet can be complex and restrictive. In addition, there are still large gaps in the literature and many foods with unclear effects in the gastrointestinal (GI) tract, like fruit juice. Although many fruits are allowable on a low-FODMAP diet, consumption of all fruit juice is generally cautioned due to the large fructose load contained in juice, regardless of the glucose concentration...

The recombinant LaSota strain expressing a chimeric IBV S1 gene (rLaSota-S1) was constructed with the S1 gene of the LX4 type IBV ck/CH/LDL/091022. The expression of the S1 protein was detected by an indirect immunofluorescence assay and Western blotting. The rLaSota-S1 strain was slightly attenuated, and its growth dynamics were similar to that of the parental LaSota strain. Vaccination of specific pathogen-free chickens with the rLaSota-S1 strain induced NDV hemagglutination inhibition antibodies, and it protected chickens from challenge with virulent NDV...

Integrin αVβ3 plays an important role in regulating cellular activities and in human diseases. Although the structure of αVβ3 has been studied by crystallography and electron microscopy, the detailed activation mechanism of integrin αVβ3 induced by fibronectin (Fn) remains unclear. In this study, we investigated the conformational and dynamical motion changes of Mn(2+) -bound integrin αVβ3 by binding to Fn with molecular dynamics simulations. Results showed that Fn binding to integrin αVβ3 caused the changes of the conformational flexibility of αVβ3 domains, the essential mode of motion for the domains of αV subunit and β3 subunit and the degrees of correlated motion of residues between the domains of αV subunit and β3 subunit of integrin αVβ3...

Severe hydropericardium syndrome (HPS) has been present in layers in the northeast of China since June 2015, with mortality rates varying from 30 to 90%. Dead layers had severe hydropericardium with pericardial volumes of 5 to 20 mL, as well as inclusion body hepatitis. Laboratory investigations led to the isolation of a fowl adenovirus strain, HLJFAd15, from the liver tissue of dead layers. Natural deletions of ORF19 and ORF27 were found in this clinical strain by complete genome sequencing, which was identified with the novel genotype recently prevalent in China...

Abnormal spermatogenesis is an important pathophysiological process underlying male infertility. Apoptosis of spermatogenic cells and disruption of ectoplasmic specialization (ES) have been characterized as the key biological events of this disorder. Under physiological and pathophysiological conditions (such as exposure to starvation, environmental chemicals, radiation), autophagy is activated in spermatogenic or Sertoli cells in order to maintain survival of the spermatogenic cells by inhibiting spermatogenic cell apoptosis and stabilizing the integrity of ES via degradation of PDZ and LIM domain 1 (PDLIM1), a negative regulator of cytoskeletal organization...

The RNA editing occurring in plant organellar genomes mainly involves the change of cytidine to uridine. This process involves a deamination reaction, with cytidine deaminase as the catalyst. Pentatricopeptide repeat (PPR) proteins with a C-terminal DYW domain are reportedly associated with cytidine deamination, similar to members of the deaminase superfamily. PPR genes are involved in many cellular functions and biological processes including fertility restoration to cytoplasmic male sterility (CMS) in plants...

Deformation twinning rarely occurs in mineral materials which typically show brittle fracture. Surprisingly, it has recently been observed in the biomineral aragonite phase in nacre under high rate impact loading. In this Letter, the twinning tendency and the competition between fracture and deformation twinning were revealed by first principles calculations. The ratio of the unstable stacking fault energy and the stacking fault energy in orthorhombic aragonite is hitherto the highest in a broad range of metallic and oxide materials...

Chlamydia suis is an endemic pig pathogen, belonging to a fascinating genus of obligate intracellular pathogens. Of particular interest, this is the only chlamydial species to have naturally acquired genes encoding for tetracycline resistance. To date, the distribution and mobility of the Tet-island is not well understood. Our study focused on whole genome sequencing of 29 C. suis isolates from a recent porcine cohort within Switzerland, combined with data from USA tetracycline-resistant isolates. Our findings show that the genome of C...
