Tiny microbes influence brain development:
Essential
- Researchers have discovered that microbes can influence the brain development of babies. Furthermore,
- The newborns who had not been in contact with these good in utero bacteria via the mother’s microbiome. Meanwhile, had more dying neurons in the paraventricular nucleus of the hypothalamus. Consequently,
- This discovery could lead to having to rethink certain obstetric practices such as the use of antibiotics during the peripartum period. Furthermore, cesarean delivery. Furthermore,
“At birth, the body of the newborn is colonized by microbes during its passage in the vaginal channel. Consequently, Birth also coincides with important developmental events which shape the brain. We wanted to explore in more detail the potential impact of the arrival of these microbes on brain development“. says Alexandra Castillo Ruiz of the tiny microbes influence brain development State University of Michigan and the main author of the study.

By studying this particular moment of life, the researcher and her colleagues discovered that microbes play an important role in early development of the brain, in particular in a key region of the brain called the paraventricular nucleus of the hypothalamus (NPV). The latter is involved in stress control, social behavior and vital functions of the body such as blood pressure.

Baby: the absence of a greater cell mortality linked to cell mortality – Tiny microbes influence brain development
During previous work, the team had noticed that the baby mouse raised without microbes had more dying neurons in the paraventricular nucleus of the hypothalamus. To determine whether this phenomenon was linked to contact with the microbes at birth. in the uterus, mournings born without any germ (because their biological mother had not) were entrusted to their birth to females carrying microbes. They were then compared tiny microbes influence brain development to control groups.
Examination of the brain of rodents only three days after birth revealed that all the little born of aseptic. mothers had less neurons in the NPV. And what they or not received microbes after birth thanks to their adoption mother.

.
During this work published in the journal Hormones and Behavior, researchers also found that aseptic adult mice had fewer neurons in the area of the brain studied.

Brain development: “microbial effects begin in the uterus”
“Our study shows that microbes play an important role in the development of a brain region essential to bodily functions and social behavior. In addition. it indicates that the microbial effects begin in the uterus, via the signaling of maternal microbes”, underlines Dr Castillo-Ruiz in a press release.
“Rather than rejecting our microbes, we should consider them as early development partners, adds the expert. They contribute tiny microbes influence brain development to the development of our brain from an early age.”

The specialist and her colleagues add that these results could shed new light on modern obstetric practices, such as the use of antibiotics in perinatal and cesarean. “Just in the United States. 40 % of women receive antibiotics before childbirth and a third of births take place by Cesarean”they recall.
