Analysis of PBMCs from SIVmac251-infected (12 wks) rhesus macaques (RMs) treated with an antibody against Programmed Death-1 (PD-1) for 14 days. Results provide insight into the molecular mechanisms by which PD-1 blockade enhances survival of SIV-infected RMs.

(Submitter supplied) Hyperimmune activation is one of the strong predictors of disease progression during pathogenic immunodeficiency virus infections and is mediated in part by sustained type I interferon (IFN) signaling. Combination antiretroviral therapy suppresses hyperimmune activation only partially in HIV-infected individuals. Here, we show that blockade of Programmed Death-1 (PD-1) during chonic SIV infection significantly reduces the expression of transcripts associated with type I IFN signaling in the blood and colorectal tissue of rhesus macaques (RM). more...

(Submitter supplied) Pathogenic HIV/SIV infection of humans and rhesus macaques (RMs) induces persistently high production of type-I interferon (IFN-I) which is thought to contribute to disease progression. To elucidate the specific role of IFN in SIV pathogenesis, 12 RMs were treated prior to i.v. SIVmac239 infection with a high or a low dose of an antibody (AGS-009) that neutralizes most IFN subtypes, and compared with six mock-infused, SIV-infected controls. more...

(Submitter supplied) Therapeutic strategies that enhance anti-viral immunity and reduce the viral reservoir are critical to achieving durable remission of HIV. The co-inhibitory receptor programmed death-1 (PD-1) regulates CD8+ T cell dysfunction during chronic HIV and SIV infections 1-4. In addition, PD-1+ CD4+ T cells constitute a significant fraction of the HIV/SIV viral reservoir5-7. We previously demonstrated that in vivo blockade of PD-1 during chronic SIV infection improves the function of anti-viral CD8+ T cells and B cells 4,8. more...

(Submitter supplied) This study describes differential miRNA expression in small intestinal lamina propria leukocyte samples longitudinally during the course of SIV infection of rhesus macaques. Notably, the T-cell activation associated miR-15b, miR-142-3p, miR-142-5p and miR-150 expression was significantly downregulated at 90 and 180DPI. Further, reporter and overexpression assays validated IRAK1 as a direct miR-150 target. more...

(Submitter supplied) Objective: To evaluate the effect of short-term type I IFN treatment on the latent viral reservoir in SIV-infected rhesus macaques on ART; Methods: We infected twelve RMs intrarectally with 10,000 TCID of SIVmac239. After 6 weeks of infection, all RMs started a three-class, four-drug ART regimen. Once viral loads were consistently undetectable, six animals were administered 1 dose of pegylated IFN-α2a per week for 4 weeks with each weekly intramuscular application being 6 µg/kg.

(Submitter supplied) In contrast to pathogenic HIV and SIV infection of humans and macaques, SIV infection of sooty mangabeys (SMs) is typically non-pathogenic despite high virus replication. A key feature of primary SIV infection of SMs is a strong type I interferon (IFN-I) response, characterized by massive up-regulation of interferon-stimulated genes (ISG), followed by rapid resolution during the acute-to-chronic phase transition and establishment of an immune quiescent state that persists throughout the chronic infection. more...

Temporal analysis of whole blood from 8 naturally SIV-infected SMs treated with recombinant RM IFNalpha2-IgFc (rmIFNα2) for 16 weeks. SIV infection of SMs is typically non-pathogenic. Results provide insight into effects of experimentally-augmented IFN-I signaling in chronically SIV-infected SMs.

(Submitter supplied) In acute HIV infection immune activation may provide target cells and drive virus replication, which innate immunity may limit. Thus, the net effects of inflammatory mediators, including type I interferon (IFN-I), are unclear. Here, we block IFN-I signaling during pathogenic acute SIV infection with an IFN-I receptor antagonist. Delayed antiviral gene expression, increased SIV reservoir, increased CD4 T cell depletion and accelerated progression to AIDS and death ensue despite decreased T cell activation. more...

We used a rhesus macaque ileal loop model to study how simian immunodeficiency virus (SIV) infection triggers defects in mucosal barrier function that enhance S. Typhimurium dissemination. SIV infection resulted in significant depletion of CD4+ T cells in the intestinal mucosa. more...

(Submitter supplied) The induction of type I interferons during acute viral infections drives local and systemic anti-viral responses. However, in chornic virus infection these type I interferon driven responses can be detrimental and can be characterized impaired immune responses (greater T cell exhaustion) and an overall decline in health outcomes. To parse out the role of type I IFN and assess the therapeutic impact of blocking type I IFN, we administered IFN-a blocking antibody to a cohort of SIV-infected ART treated Maccaca mulata. more...
