Cytokine and receptor expression in skin draining lymph nodes after skin immunization

ABSTRACT: Topical (epicutaneous, e.c.) application of the adjuvant CpG ODN during immunization leads to a robust immune response compared to when subcutaneous (s.c.) administration. Dendritic cells are hematopoietically derived cells that are important in cross-presenting to and activating CD8 T cells. Dermal dendritic cells are one of the two major dendritic cell subsets found in the skin which mobilize from the skin to draining lymph nodes to present to T cells upon activation. Dermal dendritic cells are found in skin draining lymph nodes around 24 hours post immunization. To determine how the immune system respond differently between e.c. versus s.c. administration of CpG ODN, we evaluated changes in the skin draining lymph node environment upon the two routes of adjuvant application. Expression chemokines and chemokine receptors were assessed with real-time qPCR. To determine the changes in the skin draining lymph node environment (cytokine and cytokine receptor levels) upon immunization via real time RT-PCR.

Expression data from draining lymph node of mice immunized with AS01 or its components

Project description:Immunization with adjuvanted antigen results in coordinate changes in gene expression. Combination adjuvants exploit the interplay between different immunostimulants to promote immune response to vaccination. The Adjuvant System 01 (AS01) is a liposome-based combination adjuvant which contains two immunostimulants, MPL and QS-21 Here, we assess the contribution of the components of AS01 on its immunogenicity by comparing the transcriptional response induced in the draining lymph node by AS01, MPL and QS-21 at 2,4 or 6h after intramuscolar (i.m.) immunization

single cell RNA sequencing of migratory dendritic cells after intranasal adjuvant/tolerogen administration

Project description:We compared migratory DCs in draining mediastinal lymph node after intranasal administration of different vaccine adjuvants based on CTA1 subunit of cholera toxin. The goal was to determine different characteristics of dendritic cells subsets after pro-inflammatory vs tolerogenic adjuvant. We had 3 groups: CTA1-DD (pro- inflammatory), CTA1(R7K)-DD (tolerogenic) and PBS to define DC which migrate to LN. All vaccine constructs included 3Ea peptide to allow for sorting of DC which took up the vaccine.

Murine CD4+ T cells: naive vs. experimental autoimmune uveitis

Project description:miRNA expression profiling of CD4+ T cells comparing naïve mice and experimental autoimmune uveitis (EAU) mice. EAU was induced by immunization of retinal antigen (IRBP1-20) in complete Freund’s adjuvant (CFA). CD4+ T cells were isolated and purified from the spleen and draining lymph nodes 13 days after immunization.

Microarray analysis of innate immune response induced by immunization with the adjuvant QS-21 in lymph node and muscle in mice.

Project description:The goal of this study was to identify the transcriptional mechanisms involved in the activation of the immune system by QS-21, a triterpene glycoside purified from the bark of Quillaja saponaria which has adjuvant activity in vivo. Saponins represent a promising class of vaccine adjuvant. Together with the TLR4-ligand MPL, QS-21 is part of the Adjuvant System AS01, a key component of the Malaria and Zoster candidate vaccines that display demonstrated clinical efficacy. However, the mechanism of action of QS-21 in this liposomal formulation is poorly understood. Upon intra-muscular immunisation, we observed that QS-21 rapidly accumulated in CD169+ resident macrophages of the draining lymph node where it elicited a local innate immune response. Depletion of these cells abrogated QS-21-mediated innate cell recruitment to the lymph node, dendritic cell (DC) phenotypic maturation as well as the adjuvant effect on T cell and antibody responses to co-administered antigens. DCs rather than lymph node-resident macrophages were directly involved in T cell priming by QS-21 as revealed by the decrease in antigen-specific T cell response in Batf3−/− mice. Further analysis showed that the adjuvant effect of QS-21 depended on the integration of Caspase-1 and MyD88 pathways, at least in part through the local release of HMGB1. Taken together, this work unravels the key role of lymph node sentinel macrophage in controlling the adjuvant effect of a molecule proven to improve vaccine response in humans

Expression data from draining lymph node and muscle of mice immunised with AS03 or PBS

Project description:The oil-in-water emulsion Adjuvant System 03 (AS03) is one of the few adjuvants used in licensed vaccines. AS03 induces a local and transient inflammatory response that contribute to its adjuvant effect. This data provides a more comprehensive analysis of early gene expression both at the injection site and in the draining lymph node 2, 4 or 6 hours after immunisation with AS03.

Immune response genes at the mRNA vaccine delivery sites and draining lymph nodes of rhesus macaques

Project description:mRNA vaccines are emerging as a powerful vaccine platform as they are well-tolerated and scalable. Modified non-replicating mRNA encoding Influenza hemagglutinin and encapsulated in lipid nanoparticles (LNP) induced robust antibody and CD4 T cell responses after intramuscular or intradermal delivery in rhesus macaques. We investigated the local innate immune responses modulating such vaccine-induced immunity at the sites of immunization (skeletal muscle and skin) and their draining lymph nodes (LNs). Rapid mobilization of antigen presenting cells was found at the LNP/mRNA-injection sites and LNs. Dendritic cells efficiently internalized the LNPs, translated the mRNA cargo and upregulated co-stimulatory molecules. In addition, several type I interferon-inducible genes were expressed at the immunization sites and draining LNs. The innate immune activation was transient and resulted in priming of antigen-specific CD4+ T cells exclusively in the vaccine-draining LNs. Collectively, mRNA-based vaccines induce type I interferon-polarized innate immunity and antigen production by antigen presenting cells, which resulted potent vaccine-specific responses.
