Gender and prior exposure shape innate immune responses to a replication-defective herpes virus vaccine

ABSTRACT: Here we integrate immune profiling and computational approaches to study responses to a replication-defective herpes simplex virus (HSV) 2 vaccine, in men and women either naive or previously exposed to HSV. Subjects were recipients of a herpes simplex virus (HSV) 2 vaccine in a phase 1 clinical trial where comparisons could be made between three groups of human volunteers based on their HSV serostatus prior to vaccination: HSV1-/HSV2- , HSV1+/HSV2-, or HSV1±/HSV2+ Peripheral blood transcriptomics and cell population frequencies showed the greatest changes on day 1 after vaccination. Prior exposure status and gender were independently associated with responses, but the magnitude of innate responses including type I interferon signatures and TLR7 were greatest in HSV naive women. In contrast, subjects previously infected with HSV had more prominent interferon-I responses. Thus, prior exposure and gender interact to shape innate responses that may also impact adaptive immune phenotypes, such as the neutralizing antibody response which was also faster in HSV naive women than men.

Early responding dendritic cells direct local natural killer response to control HSV-1 infection within the cornea

Project description:Dendritic cells (DCs) regulate both innate and adaptive immune responses. The role of CD11c-plus DCs in the corneal response to to herpes simplex virus-1 (HSV-1) infection was investigated by depleting them prior to infection. Bone marrow cells from CD11c-DTR (C.FVB-Tg(Itgax-DTR/EGFP)57Lan/J) mice were transferred intravenously to irradiated BALB/cJ host mice. After 6 weeks, the bone marrow chimeric host mice were injected with diphtheria toxin (DT) to deplete CD11c-positive cells. Two days after injection, the mice were subjected to a standard corneal infection protocol using HSV-1.

Gene expression in RAW264.7 cells infected with VSV and HSV-1

Project description:The purpose of this study was to determine which genes are differentially regulated virus infection in RAW264.7 cells. Cells were infected with Vesicular Stomatitis Virus (VSV) or herpes simplex virus 1 (HSV-1) for 6h. Then the differentially regulated genes were analyzed, focusing on F-box proteins and E3 ubiquitin ligases. RAW264.7 cells were infected with Vesicular Stomatitis Virus (VSV, MOI=1) or herpes simplex virus 1 (HSV-1, MOI=5) for 6h. Equal amounts of RNA were assayed for gene expression using Affymetrix mouse 430 2.0 arrays.

Gene expression in Src-/- RAW264.7 cells infected with VSV and HSV-1

Project description:The purpose of this study was to determine what are the effects of Src deficiency on innate antiviral response upon virus infection in RAW264.7 cells. Wild type and Src-/- RAW264.7 cells were infected with vesicular stomatitis virus (VSV) or herpes simplex virus 1 (HSV-1) for 6h. Then the differentially regulated genes were analyzed. Wild type and Src-/- RAW264.7 cells were infected with vesicular stomatitis virus (VSV, MOI=1) or herpes simplex virus 1 (HSV-1, MOI=5) for 6h. Equal amounts of RNA were assayed for gene expression using Affymetrix mouse 430 2.0 arrays.

RNA-Seq Time-Course Analysis of NPCs Transcriptome in Response to HSV-1 Infection

Project description:The neurogenic niches within the central nervous system serve as essential reservoirs for neural precursor cells (NPCs), playing a crucial role in neurogenesis. However, these NPCs are particularly vulnerable to infection by the herpes simplex virus type 1 (HSV-1). In the present study, we investigated the changes in the transcriptome of NPCs in response to Herpes simplex virus 1 (HSV-1) infection. Using bulk RNA-Seq, the transcriptomes of HSV-1-infected NPCs were compared to those of uninfected samples at different time points in the presence or absence of antivirals.

TMEFF1 is a neuron-specific restriction factor for herpes simplex virus

Project description:The brain is highly sensitive to damage caused by infection and inflammation. Herpes simplex virus-1 (HSV-1) is a neurotropic virus and the cause of herpes simplex encephalitis. It is unknown whether neuron-specific antiviral factors control virus replication to prevent infection and excessive inflammatory responses, hence protecting the brain. Using genome-wide CRISPR screening for HSV-1 restriction factors, we identified TMEFF1, which is expressed specifically in CNS neurons and not regulated by type I interferon, as the best-known innate antiviral system controlling virus infections. Depletion of TMEFF1 in stem-cell-derived human neurons led to elevated viral replication and neuronal death upon HSV-1 infection. TMEFF1 blocked the HSV-1 replication cycle at the level of viral entry through interactions with Nectin-1 and non-muscle myosin heavy chain IIA/B, which are core proteins in virus-cell binding and virus-cell fusion, respectively. Importantly, Tmeff1-/- mice exhibited increased susceptibility to HSV-1 infection in the brain but not in the periphery. Within the brain, elevated viral load was observed specifically in neurons. Our study identifies TMEFF1 as a neuron-specific restriction factor essential for prevention of HSV-1 replication in the CNS.

Cellular transcriptome upon HSV-1 infection or DUX4 overexpression

Project description:We found that the germline transcription factor double homeobox 4 (DUX4) is upregulated upon infection with wild-type herpes simplex virus-1 (HSV-1). The goal of this experiment was to compare the cellular transcriptome of HEK293T cells that were infected with HSV-1 (KOS strain), or transfected with a plasmid encoding human DUX4.

RNA polymerase II ChIP-seq in HSV-1 and mock infected cells

Project description:The goal of this study was to determine how RNA poymerase II (Pol II) occupancy changed in response to herpes simplex virus-1 (HSV-1) infection using ChIP-seq of Pol II. ChIP assays were performed 4 hours after cells were infected (or mock infected) with HSV-1. Because host cell Pol II transcribes the HSV-1 genome, the ChIP-seq data also reveal polymerase occupancy on the viral genome.
