1 This study was designed to simulate purine nucleoside phosphorylase (PNP) deficiency by preincubating with guanosine (Guo) to minimize PNP activity while investigating the metabolism of [14C] deoxyguanosine (dGuo) at physiologic concentrations (10 microM) by unstimulated thymocytes, tonsil-derived T and B lymphocytes, and peripheral blood cells over short time periods.
