Henderson, Eugene O. Big, and Lena Al-Harthi Division of Immunology/Microbiology, Rush University Medical Center, Chicago, ILNationalInstitute of Neurological Disease and Stroke, National Institutes of Overall health, Bethesda, MDAbstractTypically, IFN- is definitely an antiviral cytokine that inhibits the replication of numerous viruses, such as HIV. Nevertheless, inside the CNS, IFN- induces HIV-productive replication in astrocytes. Despite the fact that astrocytes in vitro are refractory to HIV replication, current in vivo proof demonstrated that astrocytes are infected by HIV, and their degree of infection is correlated with proximity to activated macrophages/microglia. The potential of IFN- to induce HIV replication in astrocytes suggests that the environmental milieu is vital in regulating the permissiveness of astrocytes to HIV infection. We evaluated the mechanism by which IFN- relieves restricted HIV replication in astrocytes. We demonstrate that despite the fact that astrocytes have robust endogenous -catenin signaling, a pathway that may be a potent inhibitor of HIV replication, IFN- diminished -catenin signaling in astrocytes by 40 , as evaluated by both active -catenin protein expression and -cateninmediated T cell factor/lymphoid enhancer reporter (TOPflash) activity. Additional, IFN- ediated inhibition of -catenin signaling was dependent on its capability to induce an antagonist of your catenin signaling pathway, Dickkopf-related protein 1, within a STAT 3-dependent manner. Inhibition of STAT3 and Dickkopf-related protein 1 abrogated the potential of IFN- to improve HIV replication in astrocytes. These data demonstrated that IFN- induces HIV replication in astrocytes by antagonizing the -catenin pathway. To our expertise, this really is the first report to point to an intricate cross-talk involving IFN- signaling and -catenin signaling that might have biologic and virologic effects on HIV outcome in the CNS, at the same time as on broader processes exactly where the two.
