چکیده

The aim of cancer vaccines is induction of tumor-specific cytotoxic T lymphocytes (CTLs) that can reduce the tumor mass. Dendritic cells (DCs) are potent antigen-presenting cells and play a central role in the initiation and regulation of primary immune responses. Thus, DCs-based vaccination represents a potentially powerful strategy for induction of antigen-specific CTLs. Fusions of DCs and whole tumor cells represent an alternative approach to deliver, process, and subsequently present a broad spectrum of antigens, including those known and unidentified, in the context of costimulatory molecules. Once DCs/tumor fusions have been infused back into patient, they migrate to secondary lymphoid organs, where the generation of antigen-specific polyclonal CTL responses occurs. We will discuss perspectives for future development of DCs/tumor fusions for CTL induction.

    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...

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...
