Metaproteomics on preterm infant stool

ABSTRACT: Development of the gut microbiota is greatly impacted in preterm infants. Despite increasing knowledge about microbiota composition in preterm infants, knowledge about the functional signatures of the intestinal microbiota remains limited. The aim was to study transitions in microbiota activity during the first six postnatal weeks in ten preterm infants. A total of 64 stool samples were measured by LC-MS/MS.

<h4>Objective</h4>Development of the gastrointestinal tract and immune system can be modulated by the gut microbiota. Establishment of the intestinal microbiota, in its turn, is affected by host and environmental factors. As such, development of the gut microbiota is greatly impacted in preterm infants, who have an immature gut and are exposed to factors like hospitalization, caesarean section, antibiotics, and respiratory support.<h4>Design</h4>We analyzed fecal microbiota composition and activ ...[more]

Monocyte signature as a predictor of chronic lung disease in the preterm infant

Project description:The early changes in innate immunity associated with BPD (bronchopulmonary dysplasia) development are incompletely understood. Transcriptome analyses from cord blood of preterm infants indicate a monocyte-centered, profibrotic signature at birth confirming TNFalpha as a critical upstream regulator for the development of BPD.

Impact of shear stretch and oxygen toxicity on pulmonary MSC of the preterm infant.

Project description:Bronchopulmonary dysplasia (BPD) represents one of the most important sequelae of preterm birth affecting more than 20% of infants born below 32 weeks. Mechanical ventilation exerting shear stress (cyclic mechanical stress, CMS) and oxygen toxicity (hyperoxia, Hox) mainly contribute to the pathogenesis of BPD. The study proposal aims to separate the impact of CMS and Hox on pulmonary mesenchymal stem cells (MSC) isolated from preterm infants participating in the DZL PROTECT-AIRR cohort study in a world-wide unique in vitro setting. The impact of rhythmic 2D and 3D stretch to MSC cell cultures alone and in combination with different fractions of oxygen is evaluated with respect to MSC phenotype, transcriptional regulation, protein alterations and paracrine secretion.

Microbiota-associated intestinal methylation changes confer immune-metabolic gene network of NEC in preterm pig model

Project description:Intestinal microbiota colonization is important for intestinal development and health of preterm infants, especially those with extremely low birth weight. Recent studies indicated for a dynamic crosstalk between that gut microbiota and DNA methylome of host intestinal cells. Thereby, we sought to determine the epigenomic and metagenomic consequences of suppression of microbiota colonization in the intestine of preterm neonates to gain insights into biological pathways that shape the interface between the gut microbiota and the preterm intestinal cells. We examined 14 preterm piglets by comparing the conventional preterm neonates with those ones treated with oral antibiotics for genome wide DNA methylation and 16S rDNA microbiome. Our results demonstrated an extensive genome-wide DNA methylation changes in response to the suppression of intestinal microbe colonization, especially genes involved in neonatal immune response signaling and glycol-metabolism pathways were identified. Our study highlights several key genes that might predispose preterm neonates to NEC risk due to their key roles involved in the immune-metabolic networks. Our study not only provided rich omic-data to interpret molecular program in relation with microbiota-associated methylome-proteome network changes, but also confer clinical usage of key gene markers for potential early diagnostics of NEC of preterm neonates.

Fecal filtrate transfer protects against necrotizing enterocolitis in preterm pigs

Project description:Necrotizing enterocolitis (NEC) is an acute and life-threatening gastrointestinal disorder afflicting preterm infants, which is currently unpreventable. Fecal microbiota transplantation (FMT) is a promising preventative therapy, but potential bacterial infection raise concern. Removal of bacteria from donor feces may reduce this risk while maintaining the NEC-preventive effects. We aimed to assess preclinical efficacy and safety of bacteria-free fecal filtrate transfer (FFT). Using fecal material from healthy suckling piglets, we administered FMT rectally, or cognate FFT either rectally or oro-gastrically to formula-fed preterm, cesarean-delivered piglets as a model for preterm infants, We compared gut pathology and related safety parameters with saline controls, and analyzed ileal mucosal transcriptome to gauge the host e response to FMT and FFT treatments relative to control. Results showed that oro-gastric FFT prevented NEC, whereas FMT did not perform better than control. Moreover, FFT but not FMT reduced intestinal permeability, whereas FMT animals had reduced body weight increase and intestinal growth. Global gene expression of host mucosa responded to FMT but not FFT with increased and decreased bacterial and viral defense mechanisms, respectively. In conclusion, as preterm infants are extremely vulnerable to enteric bacterial infections, rational NEC-preventive strategies need incontestable safety profiles. Here we show in a clinically relevant animal model that FFT, as opposed to FMT, efficiently prevents NEC without any recognizable side effects. If translatable to preterm infants, this could lead to a change of practice and in turn a reduction in NEC burden.
