In the article “Dopamine Acts as a Partial Agonist for α2A Adrenoceptor in Melanin-Concentrating Hormone Neurons,” by Christian O. Alberto, Robert B. Trask, and Michiru Hirasawa, which appeared on pages 10671–10676 of the July 20, 2011 issue, the authors wish to point out that after the submission of their manuscript, Conductier and colleagues (2011) published a report describing that α2 receptors mediate the effect of dopamine on melanin-concentrating hormone neurons. Their findings of a concentration-dependent activation of GIRK channels by dopamine in this cell type are consistent with our report.
