Abstract
Tetherin prevents viral cross-species transmission by inhibiting the release of multiple enveloped viruses from infected cells. With the evolution of simian immunodeficiency virus of chimpanzees (SIVcpz), a pandemic human immunodeficiency virus type 1 (HIV-1) precursor, its Vpu protein can antagonize human tetherin (hTetherin). Macaca leonina (northern pig-tailed macaque [NPM]) is susceptible to HIV-1, but host-specific restriction factors limit virus replication in vivo. In this study, we isolated the virus from NPMs infected with strain stHIV-1sv (with a macaque-adapted HIV-1 env gene from simian-human immunodeficiency virus SHIV-KB9, a vif gene replaced by SIVmac239, and other genes originating from HIV-1NL4.3) and found that a single acidic amino acid substitution (G53D) in Vpu could increase its ability to degrade the tetherin of macaques (mTetherin) mainly through the proteasome pathway, resulting in an enhanced release and resistance to interferon inhibition of the mutant stHIV-1sv strain, with no influence on the other functions of Vpu. IMPORTANCE HIV-1 has obvious host specificity, which has greatly hindered the construction of animal models and severely restricted the development of HIV-1 vaccines and drugs. To overcome this barrier, we attempted to isolate the virus from NPMs infected with stHIV-1sv, search for a strain with an adaptive mutation in NPMs, and develop a more appropriate nonhuman primate model of HIV-1. This is the first report identifying HIV-1 adaptations in NPMs. It suggests that while tetherin may limit HIV-1 cross-species transmission, the Vpu protein in HIV-1 can overcome this species barrier through adaptive mutation, increasing viral replication in the new host. This finding will be beneficial to building an appropriate animal model for HIV-1 infection and promoting the development of HIV-1 vaccines and drugs.

Abstract
TRIMCyp generated by retrotransposition of a cyclophilin A inserting into TRIM5 locus, has been identified in owl monkey and most of Old World monkeys (OWM). Owl monkey TRIMCyp (omTRIMCyp) inhibits HIV-1 infection by direct interaction with viral capsid and indirect innate immune induction, whereas most of TRIMCyps from OWM cannot inhibit HIV-1, and the impact of which on immunoregulation is largely unknown. Here we reported that omTRIMCyp induces NF-κB, AP-1 and IFN-β activation in a dose-dependent manner, while TRIMCyp from northern pig-tailed macaque (npmTRIMCyp) does not activate NF-κB and moderately enhances AP-1 and IFN-β activities. The Cyclophilin A (CypA) domain plays an important role in omTRIMCyp-mediated NF-κB activation, and RBCC domains have a synergetic effect. We further indicated the mechanism by which npmTRIMCyp unable to activate NF-κB is that npmTRIMCyp hardly phosphorylates IκBα, different from omTRIMCyp which dramatically induces IκBα phosphorylation. Ubiquitination activity of omTRIMCyp was greater than npmTRIMCyp, although both could be ubiquitylated. Given that npmTRIMCyp neither interacts with viral capsid resulting in susceptibility to HIV-1 infection, nor activates NF-κB that is indispensable to HIV-1 provirus transcription, we proposed a model that npmTRIMCyp may play an important role in HIV-1 infected northern pig-tailed macaque with latency.

Association of TRIMCyp and TRIM5α from assam macaques leads to a functional trade-off between HIV-1 and N-MLV inhibition. SCIENCE CHINA-LIFE SCIENCES 2018; 61:954-965. [PMID: 29705873 DOI: 10.1007/s11427-018-9295-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/19/2018] [Accepted: 04/03/2018] [Indexed: 10/17/2022]
Abstract
TRIM5α restricts retroviruses in a species-specific manner. Cyclophilin A was independently retrotransposed into the TRIM5 loci in different species, leading to the generation of antiviral TRIM5-cyclophilin A (TRIMCyp) proteins. Previously, we found that assam macaques express a TRIMCyp chimera (amTRIMCyp), along with a TRIM5α allelic protein (amTRIM5α). Herein, we investigated the antiviral activity of amTRIMCyp and amTRIM5α individually, as well as their interaction and joint effects. amTRIMCyp showed a divergent restriction pattern from amTRIM5α. Although both proteins potently restricted the replication of HIV-1, only amTRIM5α inhibited N-MLV. Remarkably, cellular anti-HIV-1 activity increased when amTRIMCyp and amTRIM5α were coexpressed, indicating a synergistic block of HIV-1 replication. Consistently, PMBCs from heterozygous amTRIM5α/TRIMCyp showed stronger resistance to HIV-1 infection than those from amTRIM5α/TRIM5α homozygotes. The anti-HIV-1 synergistic effect was dependent on the amTRIMCyp-amTRIM5α interaction. In contrast, amTRIMCyp completely abrogated the anti-N-MLV activity mediated by amTRIM5α, showing a dominant-negative effect, indicating that the generation of amTRIMCyp was involved in the trade-off between divergent restriction activities. Our results provide a new paradigm to study functional trade-offs mediated by allelic proteins, a theoretical basis for utilizing animal models with various TRIM5 alleles, as well as novel HIV-1 gene therapy strategies.

Abstract
HIV-1-infected macrophages are long-lived and act as human immunodeficiency virus 1 (HIV-1) virus reservoirs. Lipopolysaccharide (LPS) has been demonstrated to suppress HIV-1 replication in macrophages, but the mechanism is not clear. Previous research suggested that downregulation of CD4 and CCR5 as well as blockage of the interaction of HIV-1 with cells are major causes of inhibition of HIV-1 replication in macrophages by LPS. In order to study whether LPS blocks the post-entry event of HIV-1 replication, we developed a macrophage HIV-1 infection model by using VSV-G pseudotyped HIV-1-luciferase virus to infect THP-1 differentiated macrophage-like cells. We found that LPS can suppress HIV-1 replication at post-entry steps. Further study suggested that HIV-1 reverse transcription was blocked by LPS, but addition of exogenous deoxyribonucleosides led to only partial recovery of HIV-1 replication. However, the inhibition of pro-inflammatory pathway completely rescued HIV-1 replication. Thus, our study shows that LPS can suppress the events of HIV-1 replication post-entry, including reverse transcription, and this restriction is mediated by more than one mechanism.
