Aberrant survival of hippocampal Cajal-Retzius cells leads to memory deficits, gamma rhythmopathies and susceptibility to seizures in adult mice

Cajal-Retzius neurons number drastically decreases during postnatal life. Here, authors show that their programmed death is required for the construction of functional hippocampal circuits and memory with aberrant survival leading to gamma rhythmopathies and susceptibility to seizures.

Astroglial Kir4.1 potassium channel deficit drives neuronal hyperexcitability and behavioral defects in Fragile X syndrome mouse model

Fragile X syndrome is a neurodevelopmental disorder with altered neuronal excitability and behavior. Here, the authors show that dysfunction of astroglial Kir4.1 potassium channels drives neuronal and behavioral impairments in a fragile X mouse model.

Physiological synaptic activity and recognition memory require astroglial glutamine

The authors present a fluorescent probe that tracks glutamine in live cells. They demonstrate the capabilities of the probe by providing direct visual evidence of an activity-dependent glutamine supply from astroglial networks to presynaptic structures under physiological conditions.

Connexin 30 sets synaptic strength by controlling astroglial synapse invasion

Astrocytes provide essential support for and modulate synaptic transmission between neurons. Here the authors show that non-channel functions of connexin 30, a gap-junction subunit, control the synaptic coverage of astroglial processes and regulate glutamate clearance, synaptic strength and memory function.

Myotonic dystrophy RNA toxicity alters morphology, adhesion and migration of mouse and human astrocytes

Myotonic dystrophy type 1 (DM1) is characterized by debilitating neurological symptoms. Dinca et al. demonstrate the pronounced impact of DM1 on the morphology and RNA metabolism of astrocytes. Their findings suggest astroglial pathology in DM1 brain dysfunction.

Astrocytes mediate the effect of oxytocin in the central amygdala on neuronal activity and affective states in rodents

This study shows that a subpopulation of astrocytes in the central amygdala (CeA) expresses the oxytocin receptor (OTR) and that OTR activation in astrocytes underlies the anxiolytic and positive reinforcement effects of oxytocin in the CeA.

Versatile control of synaptic circuits by astrocytes: where, when and how?

Astrocytes display widespread functional diversity that translates into distinct regulation of synaptic circuits. In this Review, Dallérac and colleagues discuss the determinants of these divergent regulations throughout life focusing on astroglial intrinsic heterogeneity, developmental changes and activity-dependent processes.

Astroglial networks: a step further in neuroglial and gliovascular interactions

Astrocytes, like neurons, are organized into networks and exchange information through gap junction channels. Giaume and colleagues discuss the rules that govern communication between astrocytes and how astroglia networks can influence the function of neural networks.
