Paraoxanase-2 (PON2) activity was increased upon HIV-1 infection of the CD34+CD4+ hematopoietic cell line TF-1. Thymocytes derived from the human fetal conjoint thymus/liver hematopoietic organ of SCID-hu mice also exhibited an increase in PON2 activity. Additionally, a remarkable increase of PON2 mRNA expression was also observed in both TF-1 and thymocytes following HIV-1 infection. The phosphorylation of STAT5 was decreased in TF-1 cells upon HIV-1 infection. Interestingly, phosphorylation of STAT5 does not occur in GM-CSF "starved" TF-1 cells; however, PON2 protein, activity and mRNA expression are increased under these conditions, similar to HIV-1 infection. We conclude that PON2 is induced in HIV-1 infection through a mechanism that may involve STAT5 inactivation.
