Utilization of C-C chemokine receptor 5 by the envelope glycoproteins of a pathogenic simian immunodeficiency virus, SIVmac239.

ABSTRACT: We examined chemokine receptors for the ability to facilitate the infection of CD4-expressing cells by viruses containing the envelope glycoproteins of a pathogenic simian immunodeficiency virus, SIVmac239. Expression of either human or simian C-C chemokine receptor CCR5 allowed the SIVmac239 envelope glycoproteins to mediate virus entry and cell-to-cell fusion. Thus, distantly related immunodeficiency viruses such as SIV and the primary human immunodeficiency virus type 1 isolates can utilize CCR5 as an entry cofactor.

Changes in human immunodeficiency virus type 1 envelope glycoproteins responsible for the pathogenicity of a multiply passaged simian-human immunodeficiency virus (SHIV-HXBc2).

Project description:In vivo passage of a poorly replicating, nonpathogenic simian-human immunodeficiency virus (SHIV-HXBc2) generated an efficiently replicating virus, KU-1, that caused rapid CD4(+) T-lymphocyte depletion and AIDS-like illness in monkeys (S. V. Joag, Z. Li, L. Foresman, E. B. Stephens, L.-J. Zhao, I. Adany, D. M. Pinson, H. M. McClure, and O. Narayan, J. Virol. 70:3189-3197, 1996). The env gene of the KU-1 virus was used to create a molecularly cloned virus, SHIV-HXBc2P 3.2, that differed from a nonpathogenic SHIV-HXBc2 virus in only 12 envelope glycoprotein residues. SHIV-HXBc2P 3.2 replicated efficiently and caused rapid and persistent CD4(+) T-lymphocyte depletion in inoculated rhesus macaques. Compared with the envelope glycoproteins of the parental SHIV-HXBc2, the SHIV-HXBc2P 3.2 envelope glycoproteins supported more efficient infection of rhesus monkey peripheral blood mononuclear cells. Both the parental SHIV-HXBc2 and the pathogenic SHIV-HXBc2P 3.2 used CXCR4 but none of the other seven transmembrane segment receptors tested as a second receptor. Compared with the parental virus, viruses with the SHIV-HXBc2P 3.2 envelope glycoproteins were more resistant to neutralization by soluble CD4 and antibodies. Thus, changes in the envelope glycoproteins account for the ability of the passaged virus to deplete CD4(+) T lymphocytes rapidly and specify increased replicative capacity and resistance to neutralization.

Three-dimensional structures of soluble CD4-bound states of trimeric simian immunodeficiency virus envelope glycoproteins determined by using cryo-electron tomography.

Project description:The trimeric envelope glycoprotein (Env) spikes displayed on the surfaces of simian immunodeficiency virus (SIV) and human immunodeficiency virus type 1 (HIV-1) virions are composed of three heterodimers of the viral glycoproteins gp120 and gp41. Although binding of gp120 to cell surface CD4 and a chemokine receptor is known to elicit conformational changes in gp120 and gp41, changes in quaternary structure of the trimer have only recently been elucidated. For the HIV-1 BaL isolate, CD4 attachment results in a striking rearrangement of the trimer from a "closed" to an "open" conformation. The effect of CD4 on SIV trimers, however, has not been described. Using cryo-electron tomography, we have now determined molecular architectures of the soluble CD4 (sCD4)-bound states of SIV Env trimers for three different strains (SIVmneE11S, SIVmac239, and SIV CP-MAC). In marked contrast to HIV-1 BaL, SIVmneE11S and SIVmac239 Env showed only minor conformational changes following sCD4 binding. In SIV CP-MAC, where trimeric Env displays a constitutively "open" conformation similar to that seen for HIV-1 BaL Env in the sCD4-complexed state, we show that there are no significant further changes in conformation upon the binding of either sCD4 or 7D3 antibody. The density maps also show that 7D3 and 17b antibodies target epitopes on gp120 that are on opposites sides of the coreceptor binding site. These results provide new insights into the structural diversity of SIV Env and show that there are strain-dependent variations in the orientation of sCD4 bound to trimeric SIV Env.

Envelope vaccination shapes viral envelope evolution following simian immunodeficiency virus infection in rhesus monkeys.

Project description:The evolution of envelope mutations by replicating primate immunodeficiency viruses allows these viruses to escape from the immune pressure mediated by neutralizing antibodies. Vaccine-induced anti-envelope antibody responses may accelerate and/or alter the specificity of the antibodies, thus shaping the evolution of envelope mutations in the replicating virus. To explore this possibility, we studied the neutralizing antibody response and the envelope sequences in rhesus monkeys vaccinated with either gag-pol-nef immunogens or gag-pol-nef immunogens in combination with env and then infected with simian immunodeficiency virus (SIV). Using a pseudovirion neutralization assay, we demonstrate that envelope vaccination primed for an accelerated neutralizing antibody response following virus challenge. To monitor viral envelope evolution in these two cohorts of monkeys, full-length envelopes from plasma virus isolated at weeks 37 and 62 postchallenge were sequenced by single genome amplification to identify sites of envelope mutations. We show that env vaccination was associated with a change in the pattern of envelope mutations. Prevalent mutations in sequences from gag-pol-nef vaccinees included deletions in both variable regions 1 and 4 (V1 and V4), whereas deletions in the env vaccinees occurred only in V1. These data show that env vaccination altered the focus of the antibody-mediated selection pressure on the evolution of envelope following SIV challenge.

A molecularly cloned, pathogenic, neutralization-resistant simian immunodeficiency virus, SIVsmE543-3.

Project description:An infectious molecular clone of simian immunodeficiency virus SIVsm was derived from a biological isolate obtained late in disease from an immunodeficient rhesus macaque (E543) with SIV-induced encephalitis. The molecularly cloned virus, SIVsmE543-3, replicated well in macaque peripheral blood mononuclear cells and monocyte-derived macrophages and resisted neutralization by heterologous sera which broadly neutralized genetically diverse SIV variants in vitro. SIVsmE543-3 was infectious and induced AIDS when inoculated intravenously into pig-tailed macaques (Macaca nemestrina). Two of four infected macaques developed no measurable SIV-specific antibody and succumbed to a wasting syndrome and SIV-induced meningoencephalitis by 14 and 33 weeks postinfection. The other two macaques developed antibodies reactive in Western blot and virus neutralization assays. One macaque was sacrificed at 1 year postinoculation, and the survivor has evidence of immunodeficiency, characterized by persistently low CD4 lymphocyte subsets in the peripheral blood. Plasma samples from these latter animals neutralized SIVsmE543-3 but with much lower efficiency than neutralization of other related SIV strains, confirming the difficulty by which this molecularly cloned virus is neutralized in vitro. SIVsmE543-3 will provide a valuable reagent for studying SIV-induced encephalitis, mapping determinants of neutralization, and determining the in vivo significance of resistance to neutralization in vitro.

A Bivalent, Chimeric Rabies Virus Expressing Simian Immunodeficiency Virus Envelope Induces Multifunctional Antibody Responses.

Project description:We previously showed that a matrix (M) gene-deleted rabies virus (RABV)-based vaccine (RABV-?M) is highly immunogenic and induces potent B cell responses in the context of RABV infection. We speculated that RABV-?M expressing HIV proteins would also induce potent B cell responses against HIV antigens. As a prerequisite to future studies in nonhuman primates, we completed immunogenicity studies in mice to confirm the ability of RABV-?M to induce polyfunctional B cell responses in the context of HIV. To that end, the envelope protein from the mac239 strain of SIV (SIVmac239Env) was cloned into RABV-?M, resulting in RABV-?M-Env. Infectious virus was recovered following standard methods and propagated on baby hamster kidney cells stably expressing RABV M [>10(7) focus forming units (ffu)/ml]. Western blot analysis of cell lysates or of purified virions confirmed Env expression on the surface of infected cells and within virus particles, respectively. Positive neutralization activity against a neutralization-sensitive SIV strain and to a lesser extent against a neutralization-resistant SIV strain was detected in mice after a single intramuscular inoculation with RABV-?M-Env. The quality, but not quantity, of the antibody response was enhanced via boosting with recombinant gp130 or RABV-?M-Env as measured by an increase in antibody avidity and a skewing toward a Th1-type antibody response. We also show that an intradermal inoculation induces higher antibodies than an intramuscular or intranasal inoculation. An intradermal inoculation of RABV-?M-Env followed by a boost inoculation with recombinant gp130 produced anti-SIV antibodies with neutralizing and nonneutralizing antibody (nNAb) effector functions. Together, RABV-?M-Env induces B cells to secrete antibodies against SIV with the potential to clear both "free" and cell-associated virus. Strategies capable of eliciting both NAbs as well as nNAbs might help to improve the efficacy of HIV-1 vaccines.

CD8+ T cell-mediated CXC chemokine receptor 4-simian/human immunodeficiency virus suppression in dually infected rhesus macaques.

Project description:We coinfected rhesus macaques with CXC chemokine receptor 4- and CC chemokine receptor 5-specific simian/human immunodeficiency viruses (SHIVs) to elucidate the basis for the early dominance of R5-tropic strains seen in HIV-infected humans. We found no intrinsic barrier to the transmission and dissemination of high-dose X4-SHIV in the dually infected macaques. In animals that maintained a viral set point, the R5 virus predominated. The time of appearance of R5 dominance coincided with the development of virus-specific immunity (3-6 weeks postinfection), suggestive of differential immune control of the two viruses. Indeed, after depletion of CD8+ T cells in the coinfected animals, X4 virus emerged, supporting the concept that differential CD8+ T cell-mediated immune control of X4- and R5-SHIV replication is responsible for the selective outgrowth of R5 viruses. These findings provide critical insights into a key question related to HIV pathogenesis and have important implications for the development and testing of antiviral vaccines and therapeutics.
