Acetylcholine drives astrocytic JAK2-STAT3 signaling to modulate male-to-female approach behavior

Tom Lakomy, Camille Falconnier, Kai‐Yi Wang, Tony Barbay, Valentin Grelot, Sydney Barthelemot, Martine Guillermier, A. Chekroun, Caroline Jan, Elisa Degl’Innocenti, María-Angeles Carrillo-de Sauvage, Rémi Bos, Alexandre Charlet, Carole Escartin, Lucile Ben Haim

The paper shows that acetylcholine activates astrocytic JAK2-STAT3 signaling in male mice, which is necessary for context-appropriate approach behavior toward estrus females.

Functional contribution of astrocytic Kir4.1 channels to spasticity after spinal cord injury

Tony Barbay, Émilie Pecchi, Jorge Ramírez‐Franco, Anton Ivanov, Frédéric Brocard, Nathalie Rouach, Rémi Bos

This study shows that enhancing astrocytic Kir4.1 function reduces spasticity in SCI mice by improving K+ uptake and preventing neuronal hyperexcitability.

Astrocytes regulate locomotion by orchestrating neuronal rhythmicity in the spinal network via potassium clearance

Tony Barbay, Émilie Pecchi, Myriam Ducrocq, Nathalie Rouach, Frédéric Brocard, Rémi Bos

This study identifies astrocytic Kir4.1 channels as critical for neuronal rhythmicity in the spinal CPG, showing their role in regulating locomotion through K+ clearance.
