Listeria Monocytogenes Activated Dendritic Cell Based Vaccine for Prevention of Experimental Tumor in Mice
Background: The use of dendritic cells (DCs) as a cellular adjuvant provides a promis-ing approach in immunotherapy of cancer. It has been demonstrated that Listeria mono-cytogenes activated DCs pulsed ex vivo with tumor antigens trigger a systemic Th1-biased specific immune response and a single dose of this vaccine will cause a consider-able anti tumor immunity. Objective: The present study w...
متن کاملA Palindromic CpG-Containing Phosphodiester Oligodeoxynucleotide as a Mucosal Adjuvant Stimulates Plasmacytoid Dendritic Cell-Mediated TH1 Immunity
BACKGROUND CpG oligodeoxynucleotides (ODNs), resembling bacterial DNA, are currently tested in clinical trials as vaccine adjuvants. They have the nuclease-resistant phosphorothioate bond; the immune responses elicited differ according to the CpG ODN sequence and vaccination method. To develop a CpG ODN that can induce plasmacytoid dendritic cell (pDC)-mediated T(H)1 immunity through the mucosa...

Background & Aim: Tolerance to the semi-allogenic fetal graft by the maternal immune system is a medical enigma that has stimulated investigations for a half of century. Several hypotheses have been proposed to explain the tolerance of mother to the fetus. The successful pregnancy is proposed and proved by many scientists to be a Th2 dominant phenomenon. This hypothesis is proved in most as...

متن کاملExosomes Derived from M. Bovis BCG Infected Macrophages Activate Antigen-Specific CD4+ and CD8+ T Cells In Vitro and In Vivo
Activation of both CD4(+) and CD8(+) T cells is required for an effective immune response to an M. tuberculosis infection. However, infected macrophages are poor antigen presenting cells and may be spatially separated from recruited T cells, thus limiting antigen presentation within a granuloma. Our previous studies showed that infected macrophages release from cells small membrane-bound vesicl...
