Enhancing our understanding of pathogenic mechanisms could aid in the identification of novel therapeutic targets or vaccine candidates that could potentially decrease morbidity and mortality associated with neonatal infections.Ĭopyright © 2014, American Society for Microbiology. Collectively, these results show that GBS strains differ in their abilities to attach to distinct host cell types and express key virulence genes that are relevant to the disease process. Similar expression patterns of some genes were observed regardless of cell type used. Notably, the association with host cells resulted in the differential expression of several virulence genes relative to basal expression levels. Although the ST-23 strain attached to lung epithelial cells better than ST-17 and -19 strains, none of the strains effectively invaded the lung epithelial cells. The ST-19 and ST-23 strains, however, attached to and invaded decidual cells less than both ST-17 strains. The ST-17 strains differed in their abilities to attach to and invade decidual cells, whereas there were no differences with lung epithelial cells. Virulence gene expression following host cell association and exposure to amnion cells was also tested. We investigated whether four serotype III strains representing ST-17 (two strains), ST-19, and ST-23 differ in their abilities to attach to and invade both decidual cells and lung epithelial cells. Attachment and invasion of host cells are key steps in GBS pathogenesis. Sequence type 17 (ST-17) strains cause invasive neonatal disease more frequently than strains of other STs.

Hepatitis B MicroRNAs Single nucleotide polymorphisms.Ĭopyright © 2014 Elsevier B.V. Further epidemiological and functional studies in larger populations are warranted to verify our results. Our study first provided the evidence that rs636832 in AGO1 was associated with chronic HBV infection susceptibility in Chinese Han population. Neither did the association between rs636832 and the status of HBsAg and HbeAg (HBsAg: genotype p=0.337, allele p=0.436 HBeAg: genotype p=0.861, allele p=0.822). Further exploration for the association between rs636832 and HBV-DNA load in 329 cases showed no significant difference (genotype: p=0.321 allele: p=0.148). AA showed a risk of 1.442-fold (p=0.018) with CHB. Additionally, the dominant model AG+GG vs. The minor allele A of rs636832 was significantly associated with a decreased risk of CHB. To explore the relationship between three SNPs (rs3757 in DGCR8, rs636832 in AGO1, rs7813 in GEMIN4) in miRNA-machinery genes and chronic hepatitis B, we genotyped the SNPs by high resolution melting method (HRM) in a case-control study of 332 unrelated chronic hepatitis B patients and 352 unrelated healthy controls in Western China. he will be displaying a beautiful assortment of peacock feathers.
