Exposure of mucosal epithelial cells to the human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein gp120 is known to disrupt epithelial cell junctions by impairing stathmin-mediated microtubule depolymerization. However, the pathological significance of this process and its underlying molecular mechanism remain unclear. Here we show that treatment of epithelial cells with pseudotyped HIV-1 viral particles or recombinant gp120 protein results in the activation of protein kinase G 1 (PK ...[more]

HIV gp120 modulates the vaginal transcriptome

Project description:During sexual transmission of HIV-1 from male to female partners, the vagina is the initial site of contact with HIV infected semen. The mechanism of HIV traversing the CD4 negative multi-layered stratified squamous epithelial barrier of the vagina to infect sub-epithelial susceptible immune cells, is hitherto unknown. HIV gp120 binds to several host proteins on vaginal epithelial cells. To gain an insight into the physiologic changes that may occur in vaginal epithelial cells in response to interactions with HIV gp120, and obtain an understanding of the molecular mechanisms by which HIV breaches the vaginal epithelium, a global snap shot of gene expression profiles in the vaginal epithelial cell line Vk2/E6E7, treated with HIV gp120 was determined. The vaginal epithelial cell line Vk2/E6E7 was treated with HIV gp120 (83nM) for 24 hr, and Agilent one colour, microarrays were performed.

Transcription profiling by array of human CD4+ T-lymphocytes infected with VSVG-pseudotyped HIV-1 viruses lacking Env, Vpr, and Nef

Project description:The high mutation rate of HIV is linked to the generation of viruses expressing proteins with altered function whose impact on disease progression is unknown. We investigated the effects of HIV-1 viruses lacking Env, Vpr and Nef on CD4+ T cell gene expression using high-density DNA microarray analysis and functional assays. Experiment Overall Design: Human activated CD4+ T-lymphocytes from three independent donors were infected with HIV-1 viruses that lack Env and Nef (pNL4-3.eGFP.R+E- or HIVD2GFP) or Env, Vpr and Nef. (pNL4-3.eGFP.R-E- or HIVD3GFP) were pseudotyped with VSVG envelope. As a control, CD4+ T-lymphocytes were infected with VSVG-pseudotyped eGFP. CD4+ T-cells were sorted 48 hours after infection using GFP as a marker of infectivity. RNA was isolated 10 hours after sorting, labeled, and prepared for microarray analysis.

Sequential N/O-glycosylation analysis of heavily glycosylated HIV-1 gp120 by combination of electron-transfer/higher-energy collisional dissociation and stepped collision energy/higher-energy collisional dissociation (EThcD-sceHCD)

Project description:The envelope (Env) glycoprotein on the surface of human immunodeficiency virus type 1 (HIV-1) which decorated with a dense array of glycans is a determinant for viral invasion and host immune response of HIV-1 and a major target for a preventive HIV-1 vaccine. Improved vaccine design requires an understanding of the detailed information about the glycan type on each glycosite. Here, we used our well-established sequential glycoproteomic workflow to characterize the N/O-glycosylation of HIV-1 gp120 at the level of native intact glycopeptides based on a stepped collision energy/higher-energy collisional dissociation (sceHCD) mass spectrometry (sceHCD-MS/MS), and a combined electron transfer/higher-energy collisional dissociation (EThcD) and sceHCD mass spectrometry (EThcD-sceHCD-MS/MS).

HIV-1 gp120 impairs B cell proliferation by inducing TGF-β1 production and FcRL4 expression via an α4β7-dependent mechanism

Project description:The anti-HIV humoral immune response following acute infection is delayed and ineffective. HIV envelope protein gp120 binds to and signals through α4β7 on T cells. We show that gp120 also binds and signals through α4β7 on B cells, resulting in an abortive proliferative response. In primary B cells, gp120 signaling through α4β7 resulted in increased expression of TGF-β1 and the B cell inhibitory receptor FcRL4. Co-culture of B cells with HIV-infected autologous CD4+ T cells also resulted in increased B cell FcRL4 expression. These findings indicate that, in addition to inducing chronic immune activation, viral proteins can contribute directly to HIV-associated B cell dysfunction, thus providing a mechanism whereby the virus subverts the early HIV-specific humoral immune response.

A3G and A3F CLIP

Project description:APOBEC3G and APOBEC3F are cell-encoded restriction factors that have evolved to counteract virus infections. When packaged into HIV-1 particles, A3G and A3F impair reverse transcription and induce the hypermutation of viral DNA. We employed a next generation sequencing approach to identify the RNAs that these proteins bind in HIV-1 infected cells and HIV-1 virions. We then analysed the mechanism of packaging of APOBEC3 in detail.

Recombinant HIV-1 426c Env Tryptic Digest Glycan Identifications and Semi-Quantification

Project description:VRC01-class broadly neutralizing antibodies (bnAbs) target the CD4-binding site (CD4BS) of the human immunodeficiency virus-1 (HIV-1) envelope glycoprotein (Env) and are of major interest for vaccine design. Unlike mature antibodies, corresponding VRC01-class germline precursors poorly bind to Env due to their weak ability to overcome the steric hindrance imparted by the glycans surrounding the CD4 BS. To date, immunogen design initiatives have largely relied on removal of these glycans and have met limited success in eliciting VRC01-class bnAbs. To understand elicitation of such bnAbs in humans, we structurally characterized the inferred germline precursor of VRC01 in complex with wild-type core gp120 by X-ray crystallography and modified trimeric 426c Env constructs by single-particle electron microscopy. We then validated glycan length and composition of germline VRC01-compatible Env constructs by EThcD LC-MS/MS. Our results reveal that engagement of the VRC01 germline antibody by a wild-type 426c gp120 is possible and can be enhanced by tailoring glycan length in the vicinity of the CD4BS.
