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

Project description: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.

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.

Gene expression signatures for murine B cells from tumor-draining lymph nodes

Project description:To determine the influence of primary tumors on pre-metastatic lymph nodes, we have employed whole genome microarray expression profiling as a discovery platform to identify gene signatures of B cells from tumor-draining lymph nodes, compared with normal lymph nodes. We subcutaneously inoculated C57BL/6 mice with the 4T1 mammary carcinoma. Two weeks later, tumor-draining lymph nodes were dissociated and B cells (CD19+) were sorted. Lymph nodes B cells from normal mice without tumor bearing were set as controls.

Gene expression signatures for murine stromal cells from tumor-draining lymph nodes

Project description:To determine the influence of primary tumors on pre-metastatic lymph nodes, we have employed whole genome microarray expression profiling as a discovery platform to identify gene signatures of stromal cells from tumor-draining lymph nodes, compared with normal lymph nodes. We subcutaneously inoculated C57BL/6 mice with the 4T1 mammary carcinoma. Two weeks later, tumor-draining lymph nodes were dissociated and stromal cells (CD45-) were sorted. Lymph nodes stromal cells from normal mice without tumor bearing were set as controls.

Transcriptome of cells from draining lymph nodes of mice during experimental autoimmune encephalomyelitis (EAE)

Project description:Cells were prepared from draining lymph nodes (dLN) from naïve C57BL6/N female mice, as well as from C57BL6/N female mice at day 1 and day 3 after subcutaneous immunization with MOG(35-55) emulsified in Complete Freund’s adjuvant (CFA). Some mice received the CpG-B-1826 (50 microg; TCCATgACgTTCCTgACgTT; TIB MOLBIOL Syntheselabor GmbH), which was added to the MOG(35-55)/CFA mixture before emulsification. Cells from dLN were directly lysed in 350 microlitres RLT buffer containing 1% beta-mercaptoethanol (Invitrogen). Mice were 6-10 weeks of age at the time of immunization. The goal was to identify genes differentially expressed between dLN cells from mice immunized with the classical EAE protocol versus mice immunized with the addition of CpG-B-1826 to the immunization cocktail in order to gain some insights into the immune-modulatory effect of this treatment using an unbiased approach.

RNA-sequencing of Vg4+Vd4+gdT cells isolated from skin-draining lymph nodes of WT and NF-kB1 deficient mice after imiquiod treatment

Project description:Purpose: The numbers of Vg4+Vd4+gdT17 cells in skin-draining lymph nodes were significantly reduced in imiqimod-treated NF-kB1-/- mice compared to those in IMQ-treated WT mice. To address the mechanism of NF-kB1-mediated proliferation of Vg4+Vd4+gdT17 cells, we performed RNA-sequencing of Vg4+Vd4+gdT cells isolated from the draining lymph nodes. Method: Mice were treated daily with 50 mg of 5% imiquimod cream or sham cream on both ears for 4 days. Single cell suspensions were separated from cervical lymph nodes. Vg4+Vd4+gdT cells were isolated by a cell sorter. N=3 each. Results: Using an optimized data analysis workflow, 552 of the transcripts showed differential expression between the WT and NF-kB1 deficient mice after imiquiod treatment, with a fold change ≥2 and p value <0.05.

Discovery of genes differentially-expressed in the endothelium of lymph nodes draining metastatic versus non-metastatic tumors

Project description:Metastasis to lymph nodes is an early and prognostically important event in the progression of many human cancers, and is associated with expression of vascular endothelial growth factor-D (VEGF-D). Changes to lymph node vasculature occur during metastasis, and may establish a metastatic niche capable of attracting and supporting tumor cells. We used microarrays to characterise the molecular profiles of endothelial cells from lymph nodes draining metastatic (VEGF-D-overexpressing) and non-metastatic tumors, and to identify differentially-expressed genes that might have therapeutic or prognostic potential. Draining lymph nodes of metastatic (VEGF-D-overexpressing) or non-metastatic tumors were pooled from 1-5 mice and enzymatically digested. Lymph nodes draining metastatic tumors were included for the analysis only if macroscopically enlarged, indicating the presence of metastatic cells. After digestion, tumor cells and leukocytes were depleted via immunomagnetic selection, and the resulting lymph node stromal cells were cultured briefly. Podoplanin was then used as a positive immunomagnetic selection marker to enrich for lymphatic and other endothelial cells in the lymph node. RNA was isolated from biological duplicate lymph node endothelial cell (LN EC) preparations and analysed by microarray.
