Adenoviral vectors are crucial for gene therapy and vaccine development, offering a platform for gene delivery into host cells. Since the discovery of adenoviruses, first-generation vectors with limited capacity have evolved to third-generation vectors flacking viral coding sequences, balancing safety and gene-carrying capacity. The applications of adenoviral vectors for gene therapy and anti-viral treatments have expanded through the use of in vitro ligation and homologous recombination, along with gene editing advancements such as CRISPR-Cas9. Current research aims to maintain the efficacy and safety of adenoviral vectors by addressing challenges such as pre-existing immunity against adenoviral vectors and developing new adenoviral vectors from rare adenovirus types and non-human species. In summary, adenoviral vectors have great potential in gene therapy and vaccine development. Through continuous research and technological advancements, these vectors are expected to lead to the development of safer and more effective treatments.

Abstract

Ulcerative colitis, a major form of inflammatory bowel disease (IBD) associated with chronic colonic inflammation, may be induced via overreactive innate and adaptive immune responses. Restoration of gut microbiota abundance and diversity is important to control the pathogenesis. Lactobacillus spp., well-known probiotics, ameliorate IBD symptoms via various mechanisms, including modulation of cytokine production, restoration of gut tight junction activity and normal mucosal thickness, and alterations in the gut microbiota. Here, we studied the effects of oral administration of Lactobacillus rhamnosus (L. rhamnosus) KBL2290 from the feces of a healthy Korean individual to mice with DSS-induced colitis. Compared to the dextran sulfate sodium (DSS) + phosphate-buffered saline control group, the DSS + L. rhamnosus KBL2290 group evidenced significant improvements in colitis symptoms, including restoration of body weight and colon length, and decreases in the disease activity and histological scores, particularly reduced levels of pro-inflammatory cytokines and an elevated level of anti-inflammatory interleukin-10. Lactobacillus rhamnosus KBL2290 modulated the levels of mRNAs encoding chemokines and markers of inflammation; increased regulatory T cell numbers; and restored tight junction activity in the mouse colon. The relative abundances of genera Akkermansia, Lactococcus, Bilophila, and Prevotella increased significantly, as did the levels of butyrate and propionate (the major short-chain fatty acids). Therefore, oral L. rhamnosus KBL2290 may be a useful novel probiotic.

Abstract

Cefquinome (CEQ) is a novel β-lactam antibiotic that exhibits excellent antibacterial activity against Staphylococcus aureus. However, the bacterial protein targets of CEQ are unclear. To evaluate the relationship between the pharmacokinetic/ pharmacodynamic (PK/PD) parameters of CEQ and strains with varying degrees of resistance and to elucidate bacterial protein responses to CEQ treatment, label-free quantitative proteomics analysis was conducted. The sensitive S. aureus ATCC6538 and the resistant 2MIC and 8MIC were tested for differentially expressed proteins. An in vitro model was treated with different concentrations of CEQ (3, 5, or 10 μg/ml) with different terminal half-lives (2.5 or 5 h) at different intervals (12 or 24 h). Differentially expressed proteins were evaluated using Gene Ontology analysis followed by KEGG pathway enrichment analysis and STRING network analysis. RT-qPCR was performed to validate the differentially expressed proteins at the molecular level. The results showed that the degree of resistance increased in a cumulative manner and increased gradually with the extension of administration time. The resistant strain would not have appeared in the model only if %T > mutant prevention concentration ≥ 50%. The expression of 45 proteins significantly changed following CEQ treatment, among which 42 proteins were obviously upregulated and 3 were downregulated. GO analysis revealed that the differentially expressed proteins were mainly present on cells and the cell membrane, participated in metabolic and intracellular processes, and had catalytic and binding activities. The RPSO, SDHB, CITZ, ADK, and SAOUHSC 00113 genes in S. aureus may play important roles in the development of resistance to CEQ. These results provided important reference candidate proteins as targets for overcoming S. aureus resistance to CEQ.

Abstract

Streptococcus suis, a major swine pathogen, is an emerging zoonotic agent that causes meningitis and septic shock. Bacterial cell wall and secreted proteins are often involved in interactions with extracellular matrix proteins (ECMs), which play important roles in the initial steps of pathogenesis. In this study, 2D SDS-PAGE, western blotting-based binding affinity measurements, and microtiter plate binding assays were used to identify cell wall and secreted proteins from S. suis that interact with fibronectin and collagen type І. We identified six proteins from S. suis, including three proteins (translation elongation factor G, oligopeptide-binding protein OppA precursor, and phosphoglycerate mutase) that show both fibronectin and collagen type І binding activity. To the best of our knowledge, these three newly identified proteins had no previously reported fibronectin or collagen type І binding activity. Overall, the aim in this study was to identify proteins with ECM binding activity from S. suis and it represents the first report of six new proteins from S. suis that interact with fibronectin or collagen type І.

Abstract: Quorum sensing is a widespread chemical communication in response to fluctuation of bacterial population density, and has been implicated into bacterial biofilm formation and regulation of expression of virulence factors. The luxS gene product, S-ribosylhomocysteinase, catalizes the last committed step in biosynthetic pathway of autoinducer 2 (AI-2), a signaling molecule for inter-species quorum sensing. We found a luxS homologue in 05ZYH33, an epidemic strain of Streptococcus suis serotype 2 (SS2) in China. A luxS null mutant (ΔluxS) of 05ZYH33 strain was obtained using an approach of homologous recombination. LuxS was determined to be required for AI-2 production in 05ZYH33 strain of S. suis 2. Inactivation of luxS gene led to a wide range of phenotypic changes including thinner capsular walls, increased tolerance to H2O2, reduced adherence capacity to epithelial cells, etc. In particular, loss of LuxS impaired dramatically its full virulence of SS2 in experimental model of piglets, and functional complementation restored it nearly to the level of parent strain. Genome-wide transcriptome analyses suggested that some known virulence factors such as CPS are down-regulated in the ΔluxS mutant, which might in part explain virulence attenuation by luxS deletion. Similarly, 29 of 71 genes with different expression level were proposed to be targets candidate regulated by LuxS/AI-2-dependent quorum sensing.
