T cell-inducing heterologous vaccine against elephant endotheliotropic herpesvirus

ABSTRACT: We developed a heterologous, recombinant modified vaccinia virus Ankara prime and adjuvanted protein boost vaccine, containing the regulatory protein EE2 and the major capsid protein. The vaccine design focussed on targeting Th1 and cytotoxic T cell responses, which are crucial to herpesvirus immunity. In a proof-of-concept trial, safety and immunogenicity were tested in adult elephants. We used a modified interferon-γ release (IFNG) point-of-care vaccine-specific whole blood assay to determine T cell responses by RT-qPCR first, established to overcome quality-reducing sample transport times to the laboratory. Subsequently, RNA sequencing was utilised to understand transcriptomic changes induced by the vaccine.

RNA-sequencing reveals a distinct transcriptomic signature of chicken embryonic stem cells (cESC) infected with recombinant vaccine vectors

Project description:In this study, we used RNA-sequencing to compare the transcriptional programmes in cESC, elicited either by stimulation with recombinant interferon-α or by infection with the attenuated Fowlpox virus vaccine strain (FP9), the canarypox virus vaccine strain (CNPV), the Modified Vaccinia Ankara (MVA) virus or PBG98, a mild vaccine strain of infectious bursal disease virus.

Molecular characterisation of adipose tissue in the African elephant (Loxodonta africana)

Project description:The African elephant (Loxodonta africana) is experiencing serious challenges to optimal reproduction in captivity. The physiological and molecular basis of this impaired fertility remains unknown. A functional link between nutritional status, body condition score and fertility is well established in humans and many other species, where adipose tissue production of the hormone leptin has emerged as a crucial reproductive regulator. This report forms the basis for future studies to address the effect of nutrient composition and body condition on captive and wild elephants.

Genome-wide analysis of gene expression in lymph nodes and vaccination site in mice vaccinated with adenovirus and MVA mixed formulations

Project description:Gene expression analysis in lymph nodes and site of injection (intradermal) after vaccination with adenovirus (Ad), modified vaccinia Ankara (MVA) or a mixed formulation of Ad+MVA. The hypothesis tested in the present study was that co-administration of two viral vectors induce a differential gene expression in the site of vaccination (dermis) and the draining lymph nodes that ultimately influences the protective ability of a vaccine against pre-erythrocytic malaria.

Molecular and cellular dynamics in the skin, the lymph nodes and the blood of the immune response to intradermal injection of Modified Vaccinia Ankara vaccine

Project description:New vaccine design approaches would be greatly facilitated by a better understanding of the early systemic changes, and those that occur at the site of injection, responsible for the installation of a durable and oriented protective response. We performed a detailed characterization of very early infection and host response events following the intradermal administration of the modified vaccinia virus Ankara attenuated vaccine in non-human primates. Integrated analysis of the data obtained from in vivo imaging, histology, flow cytometry, multiplex cytokine, and transcriptomic analysis using tools derived from systems biology, such as correlation networks, showed a strong early local and systemic inflammatory response that peaked at 24 h, which was then progressively replaced by an adaptive response during the installation of the host response to the vaccine. Such comprehensive approaches should improve our understanding of how to effectively orientate the immune response, and could contribute to rational vaccine development.

Modified Vaccinia Ankara Vector-Based Vaccine Protects Macaques from SARS-CoV-2 Infection, Immune Pathology and Dysfunction in the Lung

Project description:Study show that modified vaccinia Ankara (MVA)-based COVID-19 vaccine expressing membrane anchored pre-fusion stabilized spike (MVA/S) induces both neutralizing antibodies and CD8+ T cells in the blood and lung and protects from SARS-CoV-2 challenge. Single-cell RNA sequencing analysis of lung cells at day 4 post-infection revealed that MVA/S vaccination also protected macaques from infection-induced inflammation and B cell abnormalities, and lowered induction of interferon stimulated genes.

Gene expression analysis of peripheral blood mononuclear cells prior to and following vaccination of human volunteers with the novel TB vaccine candidate MVA85A

Project description:A greater understanding of the relationships between a vaccine, the immune response it induces, and protection from disease would greatly facilitate vaccine development. Modified Vaccinia virus Ankara expressing antigen 85A (MVA85A) is a novel tuberculosis (TB) vaccine designed to enhance responses induced by Bacille Calmette-Guerin (BCG). Antigen-specific interferon-γ (IFN-γ) production is greatly enhanced by MVA85A and peaks one week post-vaccination, however, the variability in response between healthy individuals is extensive. In this study we have sought to characterize the early changes in gene expression following vaccination with MVA85A and understand how these are related to long-term immunogenicity. 24 volunteers were vaccinated with 10^8 pfu MVA85A. 12 volunteers were vaccinated intramuscularly and 12 intradermally. Volunteers were healthy and did not have HIV, HCV, HBV or latent or active tuberculosis. Blood for this study was taken on the day of vaccination, immediately prior to the vaccine being given (day 0), and 2 and 7 days post-vaccination.

Modified Vaccinia virus Ankara vector induces specific cellular and humoral responses in the female reproductive tract, the main HIV portal of entry

Project description:The female reproductive tract is one of the major mucosal invasion site of HIV-1. This site has been neglected in previous HIV-1 vaccine studies. Immune responses in the female reproductive tract after systemic vaccination remain to be characterized. Using a modified vaccinia virus Ankara (MVA) as a vaccine model, we characterized specific immune responses in all compartments of the female reproductive tract (FRT) of non-human primates after systemic vaccination. Memory T cells were preferentially found in the lower tract (vagina and cervix), whereas antigen-presenting cells and innate lymphoid cells were mainly located in the upper tract (uterus and fallopian tubes). This compartmentalisation of immune cells in the FRT was supported by transcriptomic analyses and correlation network. Polyfunctional MVA-specific CD8+ T cells were detected in the blood, lymph nodes, vagina, cervix, uterus and fallopian tubes. Anti-MVA IgG and IgA were detected in cervicovaginal fluid after a second vaccine dose. Systemic vaccination with an MVA vector thus elicits cellular and antibody responses in the female reproductive tract.

Characterization of innate immune responses to AS03 adjuvanted H5N1 vaccine compared to non-adjuvanted H5N1 vaccine.

Project description:The primary objective is to compare multiplex immune response signatures following two (primary and a boost) vaccinations with the GSK AS03 adjuvanted H5N1 influenza vaccine or the non-adjuvanted form of the H5N1 influenza vaccine at the 3.75 mcg dose and given 21 days apart and identify differences in very early innate immune responses. These immune signatures will also be correlated with the clinical observations especially safety related local and systemic events.
