THIQ treatment increase social interactions.
By Anonymous on 01/11/2019
Assay Type: In Vivo
Species: Mouse

Recently, we demonstrated that the deletion of the NFKB1 gene, which encodes the p50 NF-kappa B subunit, causes impairment in social behaviours, with reductions in social interactions in mice. In this work, we tested the acute effects of THIQ, a selective melanocortin 4 receptor (MC4R) agonist. THIQ treatment increased social interactions both in wild type and p50-/- mice. In particular, after treatment with THIQ, p50-/- mice showed a prosocial behaviour analogous to that of basal WT mice.
