Identification of the immune enhancement effect of CpG ODN on periodontitis genetic vaccine by RNA sequencing

ABSTRACT: Periodontitis is one of the main causes of tooth loss in adults. Early diagnosis and intervention can effectively control the progression of periodontitis. The research group constructed a periodontitis genetic vaccine in the early stage and improved the immunogenicity of the body by adding CpG oligonucleotide (CpG ODN). The purpose of this study was to analyse the potential mechanism by which CpG ODN adjuvants enhance the preventive effect of periodontitis genetic vaccines at the molecular level by transcriptome sequencing and to screen out key genes and signaling pathways for follow-up research.

Expression data from murine vaginal samples following adjuvant treatment

Project description:Vaccine research today is focused on using safer, highly purified or recombinant antigens with poor immunogenicity, which has created a need for potent adjuvants. Rational design of effective and safe mucosal adjuvants for human use necessitates a thorough understanding of the mode of action of successful candidate adjuvants. We used microarray to comprehend the molecular signatures of mucosal adjuvants in the mouse vagina. The adjuvants studied, CpG-ODN and ‚âà√≠¬¨¬±-GalCer have previously been shown to be potent mucosal adjuvants in mice when administrered together with a glycoprotein from HSV-2. Two individual experiments were performed, called ES1 and ES2, each experiment contained 4 groups of mice. All mice were pre-treated with progesteron (DP) before intravaginally recieveing either CpG ODN, alpha-GalCer or their respective buffers, PBS and PBS/Tween. Vaginas were excised at 3 different time-points; 4h, 24h and 48h following adjuvant delivery.

An integrated transcriptomics and metabolomics study of the immune response of newly hatched chicks to the CpG-ODN stimulation

Project description:This study aims at identifying a dual transcriptomics and metabolomics blood signature following administration of CpG-ODN (cytosine-phosphate-guanine oligodeoxynucleotides), a reference immune-stimulatory molecule. A clinical study was conducted with chicks and transcriptomics and metabolomics analyses were performed on whole-blood and plasma samples respectively. Statistical analyses resulting in lists of differentially expressed genes and metabolites with different abundance were identified in chicks treated with CpG-ODN. The results showed that CpG-ODN activates the innate immune systems within hours following administration and its effect lasts over time, as metabolomic and transcriptomic profiles are still varying at 6 days after administration.

Gene expression profile of IGROV1 cells after in vitro treatment with CpG-ODN

Project description:CpG-ODN is a potent immuno-stimulatory molecule. In order to exclude a direct effect of murine CpG-ODN on IGROV1 human ovarian cancer cell line a gene expression experiment was performed. The ovarian cancer cell line IGROV-1 was obtained from the ATCC (Rockville, MD). Cells were routinely maintained in RPMI medium 1640 (Sigma, St. Louis, MO) supplemented with 10% FCS (Sigma) and 2 mM glutamine (Cambrex, East Rutherford, NJ). Cells were maintained at 37°C in a water-saturated atmosphere of 5% CO2 in air. 1x106 IGROV-1 cells were seeded in 6-well plates and, after seeding, cells were treated with 10uM of CpG-ODN in culture medium [phosphorothioated ODN1826 (5’-TCCATGACGTTCCTGACGTT-3’), TriLink Biotechnologies (San Diego, CA, USA)] for 24 hours. At the end of treatment, cells were collected and RNA extracted.

IGROV1 miRNA expression analysis after in vivo locoregional treatment with CpG-ODN

Project description:We reported that peri-tumoral CpG-ODN treatment, probably activating TLR9-expressing cells present in the tumor microenvironment, sensitized cancer cells to DNA-damaging chemotherapy (Cancer Res 2011 Oct 15;71(20):6382-90). Here, we investigated whether this treatment induces a modulation of miRNAs and their involvement in chemotherapy sensitivity. Twenty miRNAs were found differentially expressed in tumors from CpG-ODN-treated mice versus controls. Evaluation of the role of miR-424, miR-340 and miR-302b on cisplatin sensitivity revealed that ectopic expression of miR-302b (up-modulated in our array) in IGROV1 cells significantly improved cisplatin activity. The identification of miRNAs able to modify sensitivity to chemotherapy treatment will provide an experimental base for its future possible use as a target or tool of specific therapies.
