Abstract

The gut microbiota influences brain development and functioning through the gut-brain axis. This is first study regulate maternal gut microbiota and fetal neurodevelopment processes by using probiotics such as Bifidobacterium bifidum (BIF) and Lactobacillus salivarius (LAC) in the prenatal period. In this study, Wistar Albino female rats were divided into five groups; Control, lipopolysaccharide (LPS, 100 µg/kg), LPS + LAC, LPS + BIF and LPS + LAC + BIF (4 × 10 9 ml CFU). Maternal rats were given probiotics for 21 days. Inflammation was induced by lipopolysaccharide (LPS), on the 17th day of pregnancy. After birth, the brain tissues of the maternal and neonatal rats were removed and their blood was collected. Fecal calprotectin levels of pregnant rats were measured as an important biomarker in determining intestinal flora disruption. Calprotectin levels were high in LPS group (p < 0.05). Aβ 1-42, APP, γ secretase and β- secretase levels were higher in both maternal and neonatal LPS groups (p < 0.05). These levels were statistically decreased in the probiotic groups compared to the LPS group, as demonstrated in both biochemical and histological analyzes (p < 0.05). While BDNF mRNA expression decreased in LPS groups, APP level increased in the same group. The difference between groups in mRNA expressions in the neonatal brain tissues was similar to maternal brain tissues. What's more, BDNF/actin and APP/actin rates were proven by western blot and the damage caused by neuroinflammation in the brain tissue and the preservation of the intestinal microbiota were visualized histopathologically on the morphological structures in all groups. It will shed light on new therapeutic strategies for the impact of the use of probiotics on the neurodevelopmental processes of the neonatal against LPS-induced inflammatory responses and impaired gut microbiota in the prenatal period.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
