Participation of purines in the modulation of inflammatory response in rats experimentally infected by Cryptococcus neoformans

The present study was carried out to assess the participation of purines in the activation and modulation of inflammatory response of rats experimentally infected by Cryptococcus neoformans. Twenty four Wistar rats were divided into two groups of 12 animals each: Group A - uninfected control group and Group B - infected by C. neoformans. Blood was collected 20 and 50 days post-infection (PI) from six animals of each group in order to verify purine levels (adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), adenosine (ADO), inosine (INO), hypoxanthine (HYPO), xanthine (XAN) and uric acid (URIC)). ATP levels were significantly increased (P
