Lateral septum adenosine A2A receptors control stress-induced depressive-like b...
Wang, Muran; Li, Peijun; Li, Zewen; Silva, Beatriz S. da; Zheng, Wu; Xiang, Zhenghua; He, Yan; Xu, Tao; Cordeiro, Cristina; Deng, Lu; Dai, YuweiMajor depressive disorder ranks as a major burden of disease worldwide, yet the current antidepressant medications are limited by frequent non-responsiveness and significant side effects. The lateral septum (LS) is thought to control of depression, however, the cellular and circuit substrates are largely unknown. Here, we identified a subpopulation of LS GABAergic adenosine A2A receptors (A2AR)-positive neurons...
Increased ATP release and CD73-mediated adenosine A2A receptor activation media...
Augusto, Elisabete de Oliveira; Gonçalves, Francisco Q.; Real, Joana E.; Silva, Henrique B.; Pochmann, Daniela; Silva, Tiago S.; Matos, MarcoExtracellular ATP is a danger signal to the brain and contributes to neurodegeneration in animal models of Alzheimer's disease through its extracellular catabolism by CD73 to generate adenosine, bolstering the activation of adenosine A2A receptors (A2AR). Convulsive activity leads to increased ATP release, with the resulting morphological alterations being eliminated by A2AR blockade. However, it is not known i...
Neuronal Adenosine A2A Receptors Are Critical Mediators of Neurodegeneration Tr...
Canas, Paula M.; Porciúncula, Lisiane O.; Simões, Ana Patrícia; Augusto, Elisabete de Oliveira; Silva, Henrique B.; Machado, Nuno J.; Gonçalves, NélioNeurodegeneration is a process transversal to neuropsychiatric diseases and the understanding of its mechanisms should allow devising strategies to prevent this irreversible step in brain diseases. Neurodegeneration caused by seizures is a critical step in the aggravation of temporal lobe epilepsy, but its mechanisms remain undetermined. Convulsions trigger an elevation of extracellular adenosine and upregulate...
Adenosine A₂A receptors in striatal glutamatergic terminals and GABAergic neuro...
Shen, Hai-Ying; Canas, Paula M.; Garcia-Sanz, Patricia; Lan, Jing-Quan; Boison, Detlev; Moratalla, Rosario; Cunha, Rodrigo A.; Chen, Jiang-FanAdenosine A2A receptors (A2AR) are located postsynaptically in striatopallidal GABAergic neurons, antagonizing dopamine D2 receptor functions, and are also located presynaptically at corticostriatal terminals, facilitating glutamate release. To address the hypothesis that these two A2AR populations differently control the action of psychostimulants, we characterized A2AR modulation of cocaine-induced effects at...
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...
Potential therapeutic interest of adenosine A2A receptors in psychiatric disorders
Cunha, Rodrigo A.; Ferré, Sergi; Vaugeois, Jean-Marie; Chen, Jiang-FanThe interest on targeting adenosine A(2A) receptors in the realm of psychiatric diseases first arose based on their tight physical and functional interaction with dopamine D(2) receptors. However, the role of central A(2A) receptors is now viewed as much broader than just controlling D(2) receptor function. Thus, there is currently a major interest in the ability of A(2A) receptors to control synaptic plasticit...
