Table 2 Adenosine concentration in peritoneal exudates

From: Suppression of inflammation by low-dose methotrexate is mediated by adenosine A2A receptor but not A3receptor activation in thioglycollate-induced peritonitis

  Wild-type mice (nM ± SEM) A2A knockout mice (nM ± SEM) A3 knockout mice (nM ± SEM)
Control 118 ± 6 (n = 19) 110 ± 6 (n = 14) 133 ± 6 (n = 12)
Methotrexate (0.75 mg/kg/week) 178 ± 12* (n = 15) 162 ± 7** (n = 7) 214 ± 10 (n = 9)
  1. Wild-type mice, A2A receptor knockout mice or A3 receptor knockout mice were treated with either weekly injections of methotrexate (0.75 mg/kg) or saline control for 4 weeks prior to induction of inflammation. Inflammatory exudates were induced in the peritoneum of mice, as described. After 4 hours the exudates were collected and the adenosine levels quantitated. Wild-type data are a combination from both mouse strains. *P < 0.0001 vs wild-type control mice, Student's t test; **P < 0.0001 vs A2A knockout control mice, Student's t test; P < 0.0001 vs A3 knockout control mice, Student's t test.
