AI Article Synopsis

  • The study investigates how bacterial vaginosis might contribute to preterm birth through changes in miRNA expression linked to inflammation.
  • It involved analyzing cervical swabs from 80 pregnant women, measuring bacterial presence, immune response (cytokine) levels, and 800 types of miRNAs during the mid-pregnancy period.
  • Results show that higher bacterial and cytokine levels correlate with shorter pregnancy durations, suggesting specific miRNAs could be key indicators for understanding the risk of preterm birth.

Article Abstract

Aim: Bacterial vaginosis may lead to preterm birth through epigenetic programming of the inflammatory response, specifically via miRNA expression.

Methods: We quantified bacterial 16S rRNA, cytokine mRNA and 800 miRNA from cervical swabs obtained from 80 women at 16-19 weeks' gestation. We generated bacterial and cytokine indices using weighted quantile sum regression and examined associations with miRNA and gestational age at delivery.

Results & Discussion: Each decile of the bacterial and cytokine indices was associated with shorter gestations (p < 0.005). The bacterial index was associated with miR-494, 371a, 4286, 185, 320e, 888 and 23a (p < 0.05). miR-494 remained significant after false discovery rate correction (q < 0.1). The cytokine index was associated with 27 miRNAs (p < 0.05; q < 0.01).

Conclusion: Future investigation into the role of bacterial vaginosis- and inflammation-associated miRNA and preterm birth is warranted.

Microbiota-derived proteins synergize with IL-23 to drive IL22 production in model type 3 innate lymphoid cells.

PLoS One

Microbiota-induced production of IL-22 by type 3 innate lymphoid cells (ILC3) plays an important role in maintaining intestinal health. Such IL-22 production is driven, in part, by IL-23 produced by gut myeloid cells that have sensed select microbial-derived mediators. The extent to which ILC3 can directly respond to microbial metabolites via IL-22 production is less clear, in part due to the difficulty of isolating and maintaining sufficient numbers of viable ILC3 ex vivo.

Aims: The gastrointestinal (GI) tract is composed of distinct sub-regions, which exhibit segment-specific differences in microbial colonization and (patho)physiological characteristics. Gut microbes can be collectively considered as an active endocrine organ. Microbes produce metabolites, which can be taken up by the host and can actively communicate with the immune cells in the gut lamina propria with consequences for cardiovascular health.

This study describes a complex human in vitro model for evaluating anti-inflammatory drug response in the alveoli that may contribute to the reduction of animal testing in the pre-clinical stage of drug development. The model is based on the human alveolar epithelial cell line Arlo co-cultured with macrophages differentiated from the THP-1 cell line, creating a physiological biological microenvironment. To mimic the three-dimensional architecture and dynamic expansion and relaxation of the air-blood-barrier, they are grown on a stretchable microphysiological lung-on-chip.

Assessment of bacteriological and immunological markers in urinary tract infection and the effect of antibiotics on the isolated bacteria.

Urinary tract infections (UTIs) are recognized as the second most common medical condition, following respiratory infections. Despite the availability of numerous efficacious antibiotics for the management of UTIs, the rising incidence of bacterial resistance presents significant challenges in the treatment of these infections. Bacteria are endowed with the ability to reproduce and develop resistance mechanisms against antibiotics.
