CART Restores Transient Responsiveness to IFN Type 1 in HIV-Infected Humanized Mice.

ABSTRACT: The lack of a human immunodeficiency virus (HIV) cure has heightened interest in immunotherapy. As such, type I interferons (IFNs), in particular, IFN alpha (IFN-α), have gained renewed attention. However, HIV pathogenesis is driven by sustained IFN-mediated immune activation, and the use of IFNs is rather controversial. The following questions therein remain: (i) which IFN-α subtype to use, (ii) at which regimen, and (iii) at what time point in HIV infection it might be beneficial. Here, we used IFN-α14 modified by PASylation for its long half-life in vivo to eventually treat HIV infection. We defined the IFN dosing regimen based on the maximum increase in interferon-stimulated gene (ISG) expression 6 h after its administration and a return to baseline of ubiquitin-specific proteas
