Blocking striatal adenosine A2A receptors: a new strategy for basal ganglia disorders.
Adenosine A(2A) receptors are highly concentrated in the striatum, where they play an important modulatory role of glutamatergic transmission to the GABAergic enkephalinergic neuron, which function is particularly compromised in Parkinson's disease and in the early stages of Huntington's disease. An important amount of preclinical data suggested the possible application of A(2A) receptor antago...
متن کاملP138: Are Depression and Anxiety Affected by Adenosine A2A Receptors?
Adenosine acts as neuromodulator in the brain, which its involvement in a wide range of brain processes and diseases has been studied, such as epilepsy, sleep, anxiety, panic disorder, Alzheimer’s disease, Parkinson’s disease and schizophrenia. Adenosine receptors have been detected: A1R, A2AR (A2AR), A2BR, and A3R. A1R and A2R inhibit cAMP production, while A2AR and A2BR stimulate cAMP product...

متن کاملPhysiology of basal ganglia disorders: an overview.
The pathophysiology of the movement disorders arising from basal ganglia disorders has been uncertain, in part because of a lack of a good theory of how the basal ganglia contribute to normal voluntary movement. An hypothesis for basal ganglia function is proposed here based on recent advances in anatomy and physiology. Briefly, the model proposes that the purpose of the basal ganglia circuits ...
متن کاملAdenosine A2a receptors induce heterologous desensitization of chemokine receptors.
Adenosine, released by cells in an injurious or hypoxic environment, possesses potent anti-inflammatory effects by inhibiting the production of proinflammatory cytokines and superoxide anions (O2-). We hypothesized that adenosine compounds also induced heterologous desensitization of chemokine receptors, which played a critical role in leukocyte trafficking. Our studies using adenosine receptor...
