ABSTRACT
<p><b>OBJECTIVE</b>To establish a mice model with selective inactivation adenosine A2A receptors (A2ARs) in peripheral white blood cells (PWBC).</p><p><b>METHODS</b>A2ARs were selectively inactivated in PWBCs by transplanting bone marrow cells (BMCs) from A2AR knockout (KO) mice into their wild type (WT) littermates after a single total body irradiation of 9.5 Gy or fractionated total body irradiation of 6.2 Gy x 2. The efficiency of reconstitution of bone marrow-derived cells in chimeric mice was assessed.</p><p><b>RESULTS</b>PCR band patterns changed from the recipient pattern (one band of 330 bp) to the donor (two bands of 300 and 330 bp) pattern. Immunohistochemistry analysis showed that 10.21% of cells were A2AR+ in PWBCs in KO--> WT mice, whereas 96.72% of cells were A2AR+ in WT mice. The survival rates of mice irradiated with 6.2 Gy x 2 and transplanted with more than 6 x 10(6) BMCs were about 91%.</p><p><b>CONCLUSION</b>A murine model of selective inactivation adenosine A2A receptors in PWBCs was established successfully.</p>
