circHIPK2 was detected in GFAP-positive astrocytes in mouse hippocampi by in situ hybridization combined with immunostaining. The study links circHIPK2 to astrocyte dysfunction in CUS-induced depressive-like behavior.
Gut microbiota from NLRP3-deficient mice ameliorates depressive-like behaviors by regulating astrocyte dysfunction via circHIPK2.
