an endogenous immune adjuvant released by necrotic cells for enhancement of dna vaccine potency
نویسندگان
چکیده
background: improving vaccine potency in the induction of a strong cell-mediated cytotoxicity can enhance the efficacy of vaccines. necrotic cells and the supernatant of necrotic tumor cells are attractive adjuvants, on account of their ability to recruit antigen-presenting cells to the site of antigen synthesis as well as its ability to stimulate the maturation of dendritic cells. objective: to evaluate the utility of supernatant of necrotic tumor cells as a dna vaccine adjuvant in a murine model. method: the supernatant of el4 necrotic cells was co-administered with a dna vaccine expressing the glycoprotein b of herpes simplex virus-1 as an antigen model under the control of cytomegalovirus promoter. c57bl/6 mice were vaccinated three times at two weeks intervals with glycoprotein b dna vaccine and supernatant of necrotic el4 cells. five days after the last immunization, cell cytotoxicity, ifn-γ and il-4 were evaluated. results: the obtained data showed that the production of ifn-γ from the splenocytes after antigenic stimulation in the presence of the supernatant of necrotic el4 cells was significantly higher than the other groups (p

متن کاملHMGB1 is an endogenous immune adjuvant released by necrotic cells.
Immune responses against pathogens require that microbial components promote the activation of antigen-presenting cells (APCs). Autoimmune diseases and graft rejections occur in the absence of pathogens; in these conditions, endogenous molecules, the so-called 'innate adjuvants', activate APCs. Necrotic cells contain and release innate adjuvants; necrotic cells also release high-mobility group ...
متن کاملCpG-DNA enhancement the immune elicited as adjuvant of foot- and- mouth disease vaccine
In the present study the effect of the locally produced genetic adjuvant of ginea pig specific CpG-motif-containing oligodeoxynucleotide (CpG-ODN) in an inactivated FMD virus vaccine was evaluated. Boosting the ginea pigs with FMD vaccine along with CpG-ODN adjuvant produced relatively higher ratio (5-fold) of FMDV-specific IgG2a / IgG1 than those vaccinated in the absence of CpG-ODN. The neutr...

متن کاملEnhancement of DNA vaccine potency by linkage of antigen gene to an HSP70 gene.
Nucleic acid vaccines represent an attractive approach to generating antigen-specific immunity because of their stability and simplicity of delivery. However, there is still a need to increase the potency of DNA vaccines. Using human papillomavirus type 16 E7 as a model antigen, we evaluated the effect of linkage to Mycobacterium tuberculosis heat shock protein 70 (HSP70) on the potency of anti...
