Minocycline engages microglia in the midbrain periaqueductal grey to attenuate hypoxia-triggered panic-like behaviour in rats

Arthur Rocha‐Gomes, Jefferson Manoel Nascimento‐Silva, Beatriz Cassimiro Baratella…·Hélio Zangrossi

This study shows that minocycline reduces panic-like behavior in rats exposed to hypoxia by preventing microglial morphological changes in the midbrain periaqueductal grey.

Activation of the TRKB receptor mediates the panicolytic-like effect of NOS inhibitor aminoguanidine

Deidiane Elisa Ribeiro, Plinio Cabrera Casarotto, Ailton Spiacci…·Caroline Biojone

The paper shows that repeated aminoguanidine administration increases TRKB phosphorylation in the dPAG, which is necessary for its panicolytic-like effect in rats.
