WebNov 16, 2024 · The D2 receptor modulation of PI3K-Akt is a signaling mechanism independent from cAMP/PKA activity. Interestingly, the relationships of the D2 receptor with these cascades are dissociable, and β-arrestin-2 only activates downstream effectors under specific conditions (Peterson et al. 2015). WebMar 21, 2024 · As a result, we observed an increase in the expression of mRNA encoding the regulator of G protein signaling 2-RGS2 protein, which is responsible, among other things, for internalizing the D2 dopamine receptor. The increase in RGS2 expression may therefore account for the decreased binding of the radioligand to the D2 receptor.
