Synaptic dysfunction is thought to underlie altered sociability in autism. However, the gene regulatory mechanisms that control synaptic protein expression in the context of social behaviour are poorly explored. Here we show that deletion of the large placental mammal specific miR379-410 cluster in mice leads to hypersocial behaviour, increased excitatory synaptic transmission and exaggerated expression of ionotropic glutamate receptor complexes in the hippocampus. Thus, interfering with miR379-410 could represent a novel therapeutic strategy for social deficits in autism.

View SamplesIntact living conduit vessels (umbilical veins) were exposed to normal or high intraluminal pressure, or low or high shear stress in combination with a physiological level of the other force. We used a unique vascular ex vivo perfusion system. After six hours of perfusion endothelial cells were isolated from the stimulated vessels and RNA was extracted. RNA from 16 experiments from each stimulation were pooled and analyzed in duplicate DNA microarrays.

View SamplesAstroglial cells in the adult brain constitute a heterogeneous population endowed with region-specific properties. Recently, they have acquired greater relevance as active components of the adult neural stem cell (aNSC) niches. Astrocytes located in the vicinity of aNSC reservoirs are thought to regulate aNSC behaviour. We have compared the function of glial cells isolated from the postnatal and adult subventricular zone and hippocampus (two stem cell niches, where aNSCs self-renew and give rise to immature neurons), from the olfactory bulb (a neurogenic region where the immature neurons cease to proliferate and terminally differentiate) and from a non-stem and non-neurogenic area such as the ventral mesencephalon. Co-culture experiments demonstrate that subventricular zone glial cells secrete soluble signals that promote NSC self-renewing divisions.

Collected hearts were micro-dissected into 3 parts (atria, ventricle, and outflow tract), which were further digested into single cardiac cells and subject to single-cell RNA-seq analyses.
