In this study the transcriptomic profiling of adenosine receptors (ARs) in human leukocytes of heart failure (HF) patients as a function of clinical severity, assessing the possible changes with respect to healthy subjects ( ), was evaluated. Total RNA was extracted from leukocytes of ( ) and of HF patients (NYHA I-II ; NYHA III-IV ) with a PAXgene Blood RNA Kit. An increase as a function of clinical severity was observed in each AR (A1R: , NYHA , NYHA ,    versus NYHA III-IV, NYHA I-II versus NYHA III-IV; A2aR: , NYHA , NYHA ,    versus NYHA III-IV, NYHA I-II versus NYHA III-IV; A2bR: , NYHA , NYHA , : NYHA I-II versus NYHA III-IV; A3R: , NYHA , NYHA ,    versus NYHA III-IV and NYHA I-II versus NYHA III-IV, resp.). The mRNA expression of the ectonucleoside triphosphate diphosphohydrolase (CD39) and the ecto-5′-nucleotidase (CD73) were also evaluated. They resulted up-regulated. These findings show that components of adenosine metabolism and signalling are altered to promote adenosine production and signalling in HF patients. Thus, HF may benefit from adenosine-based drug therapy after confirmation by clinical trials.
