Project description:Immune Response of Immature Dendritic Cells after Infection with Human Cytomegalovirus Strain TB40E

Project description:Analysis of dendritic cells (DCs) at 6h and 48h after infection with cytomegalovirus (CMV) versus non infected. CMV tends to induce immunosuppression followed by lasting immunity. DCs appear to play a role in this effect. Results provide insights into CMV/DC interactions and suggest mechanisms for CMV-regulated early immune response. Keywords: gene expression array-based, count In the present study, immature monocyte-derived dendritic cells were generated from CMV neg healthy blood donors and infected or not with an endotheliotropic CMV strain. Gene expression modulation by the CMV infection was studied in a time course assay (non-infected - NI - vs 6h or 48h post-infection. Patient C has no 48h sample

Project description:Ducks and wild aquatic birds are the natural reservoirs of avian influenza viruses. However, the host proteome response that causes disease in vivo during infection by the highly pathogenic avian influenza (HPAI) H5N1 virus is still not well understood. In the present study, we compared the proteome response in Muscovy duck lung tissue during 3 day of infection with either a highly virulent or an avirulent H5N1 virus. During infection, proteins involved in immune response of neutrophils and size of cells were increased markedly in the lung by the virulent strain, while the avirulent strain evoked a distinct response, characterized by an increase in proteins involved in cell movement, maturation of dendritic cells, adhesion of phagocytes, and immune response of macrophages.

Project description:Fribourg2014 - Dynamics of viral antagonism and innate immune response (H1N1 influenza A virus - Cal/09)
The dynamics of the interplay between the viral antagonism and the innate immune response has been studied using modelling approaches. The responses of human monocyte-derived dendritic cells infected by two influenza A H1N1 strains (the pandemic swine-origin A/California/4/2009 (Cal/09) and the seasonal A/New Caledonia/20/1999 (NC/99)) that have different clinical outcomes have been modelled. From the time course gene expression measurements of a set of selected genes, the dynamic features of viral antagonism and innate immune response are extracted. It is found that the strength and the time scale of action of viral antagonism is significantly different between the two viruses. This model describes the viral infection by seasonal Cal/09.

Abstract:
Viral antagonism of host responses is an essential component of virus pathogenicity. The study of the interplay between immune response and viral antagonism is challenging due to the involvement of many processes acting at multiple time scales. Here we develop an ordinary differential equation model to investigate the early, experimentally measured, responses of human monocyte-derived dendritic cells to infection by two H1N1 influenza A viruses of different clinical outcomes: pandemic A/California/4/2009 and seasonal A/New Caledonia/20/1999. Our results reveal how the strength of virus antagonism, and the time scale over which it acts to thwart the innate immune response, differs significantly between the two viruses, as is made clear by their impact on the temporal behavior of a number of measured genes. The model thus sheds light on the mechanisms that underlie the variability of innate immune responses to different H1N1 viruses.

Project description:This study is being conducted to determine the efficacy, side effects, and toxicity of an investigational vaccine that consists of tumor-pulsed dendritic cells administered with an immune stimulating drug called interleukin-2 (IL-2). Dendritic cells are immune cells that are obtained from a subject’s blood and are important in the body’s immune response to foreign substances. This study will examine the response of a subject’s immune system after receiving several vaccinations containing their own dendritic cells which have been exposed to dead fragments of their cancer cells in the laboratory. This may result in sensitizing a subject’s dendritic cells to their cancer cells so that their dendritic cells will react with other cells of the immune system and attack the cancer. It has been shown in the laboratory that dendritic cells exposed to cancer cell fragments can provide lymphocytes (a type of white blood cell) with signals they require in order to become fully activated and acquire the ability to kill cancer cells.

Project description:Innate sensing of viruses by dendritic cells (DCs) is critical for the initiation of anti-viral adaptive immune responses. Virus, however, have evolved to suppress immune activation in infected cells. We now analyze the susceptibility of different populations of dendritic cells to viral infections. We find that circulating human CD1c+ DCs support infection by HIV and influenza virus. Viral infection of CD1c+ DCs is essential for virus-specific CD8+ T cell activation and cytosolic sensing of the virus. In contrast, circulating human CD141+ DCs and pDCs constitutively limit viral fusion. The small GTPase RAB15 mediates this differential viral resistance in DC subsets through selective expression in CD141+ DCs and pDCs. Therefore, dendritic cell sub-populations evolved constitutive resistance mechanisms to mitigate viral infection during induction of antiviral immune response.
