Adenosine A2A receptor antagonists exert motor and neuroprotective effects by d...
Yu, Liqun; Shen, Hai-Ying; Coelho, Joana E.; Araújo, Inês M.; Huang, Qing-Yuan; Day, Yuan-Ji; Rebola, Nelson; Canas, Paula M.; Rapp, Erica KirstenTo investigate whether the motor and neuroprotective effects of adenosine A2A receptor (A2AR) antagonists are mediated by distinct cell types in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model of Parkinson's disease.We used the forebrain A2AR knock-out mice coupled with flow cytometric analyses and intracerebroventricular injection to determine the contribution of A2ARs in forebrain neurons and gl...
Adenosine A2A receptors control the extracellular levels of adenosine through m...
Pinto-Duarte, António; Coelho, Joana E.; Cunha, Rodrigo A.; Ribeiro, Joaquim Alexandre; Sebastião, Ana M.Adenosine, a neuromodulator of the CNS, activates inhibitory-A1 receptors and facilitatory-A2A receptors; its synaptic levels are controlled by the activity of bi-directional equilibrative nucleoside transporters. To study the relationship between the extracellular formation/inactivation of adenosine and the activation of adenosine receptors, we investigated how A1 and A2A receptor activation modifies adenosine...
