Abstract:

Recently, several studies have demonstrated that G protein coupled receptors exist as homo/heterodimers or oligomers. Adenosine A2A receptors and dopamine D2 receptors are present as both homo- and heterodimer. In the GABAergic striatopallidal neurons A2AR are co- localized with D2 receptors (D2R), and establish functional A2AR-D2R heteromers, which modulates dopaminergic activity. Due to be involved in physiological processes, these receptors bear critical roles. Dopamine receptors play critical role in dopaminergic pathways in regulation of memory, food intake and psychomotor activity, etc.

Abstract:

Background and rationale - Parkinson’s disease is a neurodegenerative disorder characterised by reduced levels of dopamine in the brain. The cause of Parkinson's disease is still unknown; however several theories pertaining to the etiology exist. Current treatment mainly aims at dopamine replacement, with agents such as levodopa and dopamine agonists that provide patients with symptomatic relief. This relief is unfortunately only temporary as the progression of the disease is not halted. Furthermore, these therapies are associated with a range of side effects and novel approaches to the treat

Abstract:

Myocardial fibrosis contributes to the pathogenesis of diverse forms of cardiac hypertrophy. Recent evidence suggests a crucial role for purinergic signalling in the formation of tissue fibrosis. In particular, inhibition of adenosine A2A receptors (A2AR) in animal models for hepatic and skin fibrosis resulted in a reduction of fibrosis formation. The specific hypothesis of this investigation was that myocardial stress results in increased interstitial levels of adenosine, which activate cardiac fibroblasts via adenosine A2AR. Accordingly, the specific objective of this investigation was to de

However, the function of this receptor in the CNS remains unknown. The interest on GPR37 biology was bolstered when it was described as a Parkin substrate.

Endothelial inflammation leading to vascular dysfunction is a major contributor to the development of atherosclerosis. The release of adenosine at sites of inflammation represents an endogenous mechanism for limiting excessive inflammation and tissue damage.

Little is known about the molecular mechanisms behind these effects. However, in vitro studies using cultured endothelial cells indic

Abstract:

Dissertação de Mestrado em Genética Molecular Comparativa e Tecnológica<br>A Hipertensão Arterial Pulmonar (HAP) é uma doença complexa e multifactorial que induz uma sobrecarga no coração, devido ao aumento da resistência da circulação pulmonar. Neste cenário de aumento de resistência da circulação pulmonar, o lado direito do coração fica sobrecarregado, conduzindo à remodelação tissular do miocárdio e, eventualmente, falência do ventrículo direito (VD). A adenosina (ADO) é uma molécula de sinalização que é ubíqua e capaz de modular a função cardíaca mediante a interação com vários subtip

Abstract:

Obesity is a significant health care problem, affecting more than one third of the United States population and is an important risk factor for Type 2 Diabetes Mellitus (T2D). Adipose tissue expansion results in the recruitment and accumulation of macrophages, which secrete proinflammatory cytokines that impair insulin signaling. Adenosine regulates inflammation by signaling through G-protein coupled receptors (GPCRs), such as the A2b adenosine receptor (A2bAR). Recently a role for adenosine receptors has been described in the differentiation of osteoblasts and adipocytes. This thesis tests t

Abstract:

A hipertensão arterial pulmonar (HAP) é uma doença progressiva e potencialmente fatal que afeta a vasculatura pulmonar e, consequentemente, o coração. Esta doença cardiopulmonar é caracterizada por uma ampla variedade de fatores desencadeadores iniciais que promovem a remodelação da vasculatura pulmonar, aumentando a sua resistência ao fluxo sanguíneo. Este estado de elevada resistência circulatória pulmonar sobrecarrega o ventrículo direito (VD). A sobrecarga contínua exercida pelo incremento da pressão da artéria pulmonar é agravada pelo aumento da massa muscular (remodelação do VD) no senti

Adenosine acts onto a G protein–coupled receptors (GPCRs) subfamily called P1 adenosine receptors: A1R, A2AR, A2BR and A3R. Adenosine type 2A receptor (A2AR) is highly expressed in striatum, whereas in other brain regions A2AR is expressed at lower levels. One of these regions is the hippocampus, a central brain region enrolled in learning an

Estudos demonstraram que os recetores A2A de adenosina (A2AR) e D2 de dopamina (D2R) acoplados à proteína G formam heterómeros A2AR-D2R no estriado. A estequiometria deste heterómero encontra-se alterada na doença de Parkinson (DP) e a sinalização mediada pelos recetores A2A pode ser promovida. Deste modo, os recetores A2A são o alvo farmacológico de eleição na DP que mais tem recebido atenção nos últimos ano

Abstract:

碩士<br>國立陽明大學<br>神經科學研究所<br>89<br>The rat A2A adenosine receptor (A2A-R) is heavily enriched in the striatum and is also expressed at relatively low levels in other areas of the brain. Gene of A2A-R contains two independent promoters (P1 and P2). Transcripts produced from these two promoters differ in the length of their 5'-untranslated regions (5'-UTR), but encode the same protein. To further characterize the transcriptional regulation of the A2A-R gene in vivo, a fusion gene consisting the 4.8 kb 5'-flanking region / full length 5'UTR of the A2A-R gene and the coding region of the N-lacZ (n-β
