Project description:The goal of this study was to compare cell composition, gene expression, and infectivity of different cell types in human airway epithelia following exposure to measles virus. Samples included control epithelia exposed to a mock infection and measles-virus-exposed epithelia that were sorted according to detection of green fluorescent protein (GFP) prior to library preparation and sequencing.

Project description:In humans, lymph nodes are the primary site of measles virus (MeV) replication. To understand the immunological events that occur at this site, we infected human lymphoid tissue explants using a pathogenic strain of MeV that expresses GFP. We found that MeV infected between 5-15% of cells across donors. Using single cell RNA-Seq (scRNA-Seq) and flow cytometry, we found that while most of the 29 cell populations identified in the lymphoid culture were susceptible to MeV, there was a broad preferential infection of B cells and reduced infection of T cells. Further subsetting of T cells revealed that this reduction may be driven by the decreased infection of naïve T cells. Transcriptional changes in infected B cells were dominated by an interferon stimulated gene (ISG) signature. To determine which of these ISGs were most substantial, we evaluated the proteome of MeV-infected Raji cells by mass spectrometry. We found that IFIT1, IFIT2, IFIT3, ISG15, CXCL10, MX2, and XAF1 proteins were the most highly induced, and positively correlated with their expression in the transcriptome. These data provide insight into the immunological events that occur in lymph nodes during infection and may lead to the development of therapeutic interventions.

Project description:The major inducible 70 kDa heat shock protein (hsp70) is host protective in a mouse model of measles virus (MeV) brain infection. Transgenic constitutive expression of hsp70 in neurons, the primary target of MeV infection, abrogates neurovirulence in neonatal H-2d congenic C57BL/6 mice. A significant level of protection is retained after depletion of T lymphocytes, implicating innate immune mechanisms. Focus of the present work was to elucidate the basis for hsp70-dependent innate immunity using this model. Transcriptome analysis of brains from transgenic (TG) and non-transgenic (NT) mice 5 days after infection identified type 1 interferon (IFN) signaling and macrophage activation/antigen presentation as the main differences linked to survival. The pivotal role for type 1 IFN in hsp70-mediated protection was demonstrated in mice with a genetically disrupted type 1 IFN receptor (IFNAR-/-), where IFNAR-/- eliminated the difference in survival between TG and NT mice. Brain macrophages, not neurons, are the predominant source of type 1 IFN in the virus-infected brain, and in vitro studies provided a mechanistic basis by which MeV-infected neurons can induce IFN-β in uninfected microglia in an hsp70-dependent manner. MeV infection induced extracellular release of hsp70 from mouse neuronal cells that constitutively express hsp70, and extracellular hsp70 induced IFN-β transcription in mouse microglial cells through Toll-like receptors 2 and 4. Collectively, results support a novel axis of type 1 IFN-dependent antiviral immunity in the virus-infected brain that is driven by hsp70.

Project description:Measles virus infects serum activated airway epithelial cells and many adenocarcinoma cell lines. A microarray analysis was performed on virus permissive versus non-permissive cells. Membrane protein genes that were upregulated in permissive cells were tested as receptor/entry factors. Membrane protein genes that were upregulated in smooth airway epithelial cells (SAEC) following growth in 10% fetal calf serum that made the cell line permissive to measles virus were identified. Membrane protein genes that were upregulated in adenocarcinoma cells that were permissive to wild type measles virus infection were identified. [SAEC]: Airway cells (SAEC) grown in serum free media (SAGM) were purchaced from Lonza. Half the cells were cultured in SAGM, the other half were transferred into Dulbecco's 10% fetal calf serum for 24 hrs. RNA was harvested from the cells by the Qiagen RNAeasy [Adenocarcinoma cells]: MCF7, MDA-MB-468, T47D, NCI-H358, NCI-H125, MGH24 cells were permissive and A549 and MDA-MB-231 cells were non-permissive.

Collectively, results support a novel axis of type 1 IFN-dependent antiviral immunity in the virus-infected brain that is driven by hsp70. Hsp70 expression in mice enhances gene expression related to antiviral immune response against MeV neurovirulence. We performed microarrays on whole brain tissues in mice to obtain an unbiased picture of how hsp70 alters host innate responses to viral infection. Hsp70-overexpressing transgenic (TG) and non-transgenic (NT) mice were infected with MeV intracranially, and total brain mRNA harvested at 5 and 10 days post infection (d.p.i.) was analyzed, sampling the hemisphere opposite the side of viral inoculation. Analysis includes 6 groups: infected TG at 5 d.p.i. (n=4), infected TG at 10 d.p.i. (n=5), infected NT at 5 d.p.i. (n=4), infected NT at 10 d.p.i. (n=5), uninfected TG at 5 d.p.i. (n=4), and uninfected NT at 5 d.p.i. (n=4).
