1 Deletion of the serotonin transporter perturbs BDNF signaling in the central amygdala following long-access cocaine self-administration. Cocaine solute carrier family 6 member 4 Rattus norvegicus
2 Additionally, while BDNF is strongly regulated by serotonin levels and inherited serotonin transporter down-regulation is associated with increased vulnerability to cocaine addiction, the effects of serotonin transporter genotype on BDNF signaling in the amygdala under naive and cocaine exposure conditions are unknown. Cocaine solute carrier family 6 member 4 Rattus norvegicus
3 mBDNF protein expression and its signaling in cocaine-naive serotonin transporter knockout rats resembled that of wild-type rats with a history of long-access cocaine self-administration. Cocaine solute carrier family 6 member 4 Rattus norvegicus
4 Interestingly, cocaine-exposed serotonin transporter knockout rats showed increased BDNF levels, with no signs of phospho-TrkB receptor coupling to phospho-Akt and phospho-ERK1. Cocaine solute carrier family 6 member 4 Rattus norvegicus
