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.

Oxytocin Gαi signaling-induced amygdala astrocytes processes retraction shapes behavioral stress response

Angel Baudon, Valentin Grelot, Ferdinand Althammer, Kai‐Yi Wang, Clémence Denis, Syed Azmal Ali, Yudong Yan, Fernando Castillo Díaz, Francesca Piacentini, Etienne Clauss Creusot, Volodya Hovhannisyan, Tim Schubert, Annabel C. Kleinwaechter, Jemima Helen, Tom Lakomy, , Alexandre Charlet

The paper shows that oxytocin-induced astrocyte process retraction in the amygdala modulates freezing behavior during stress by enhancing neuronal sensitivity to potassium.
