16S rRNA sequencing

Environmental enrichment (EE) is a husbandry procedure known to provide enhanced somatosensory, locomotor and cognitive stimulation. It has been shown to exert significant beneficial effects on cognitive function improving rodent behavior, altering neuronal plasticity, and promoting stress resilience. Concurrently, emerging research highlights the intricate bidirectional communication between the gut microbiome and central nervous system, known as the microbiota-gut-brain axis. Therefore, the aim of this work is to investigate, whether the beneficial effects of EE are linked to alterations in

Consequences of children brain exposure to radiation (doses ≤ 2 Gy) are not clearly established. The advent of computed tomography scans use for head exploration as well as a recent increase in the use of interventional neuroradiology in pediatrics raised the need to improve our knowledge of these effects. To understand how irradiation may affect the developing brain, we previously developed models of either whole brain or hippocampal dorsal dentate gyrus irradiation in ten-day-old male mice (doses ≤ 2 Gy) and demonstrated some alterations in adult mice behavior and in hippocampal neurogenesis

…Fecal pellets were collected for 16S rRNA sequencing and animals were subsequently euthanized. Our data revealed that rotenone and its combination with HFD exhibited loss of motor fu

The role of dysregulated gut microbiota (GM) is widely recognized as relevant to the pathogenesis of Parkinson's disease (PD), particularly in case of non-motor symptoms such as depression and anhedonia. Most transgenic mouse models of PD, however, don’t exhibit clinically relevant dysbiosis. Here, for the first time, we present the GM composition and depression-like behavior in Hualpha-Syn(A53T) transgenic mice, line G2-3, which over-express human α-synuclein and are the only model of PD that exhibits prodromal constipation. Additionally, we investigated whether sharing social microenvironmen
