title: Propentofylline inhibits production of TNFalpha and infection of LP-BM5 murine leukemia virus in glial cells.
abstract: We examined the effects of a xanthine derivative, propentofylline, on TNFalpha production by glial cells and on infection ofglial cells with a murine leukemia virus, LP-BM5, which induces murine AIDS in susceptible mice. Propentofylline suppressed TNFalpha production in glial cells and also effectively suppressed infection ofglial cells with LP-BM5 in vitro. Addition ofTNFalpha, but not IL-1 or IL-6, abolished the suppressive effects ofpropentofylline. Anti-TNFalpha antibody also suppressed infection of LP-BM5 in these cells. These findings suggest that propentofylline suppressed LP-BM5 infection in glial cells by suppressing TNFalpha production by these cells. Because propentofylline reportedly passes through the blood-brain barrier, it may be useful in the treatment of central nervous system involvement by HIV infection or neurological diseases in which TNFalpha plays a causative role, such as multiple sclerosis.
