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 کاملDNA vaccination protects mice against challenge with Listeria monocytogenes expressing the hepatitis C virus NS3 protein.
The goal of this study was to develop a new surrogate challenge model for use in evaluating protective cell-mediated immune responses against hepatitis C virus (HCV) antigens. The use of recombinant Listeria monocytogenes organisms which express HCV antigens provides novel tools with which to assay such in vivo protection, as expression of immunity against this hepatotropic bacterial pathogen i...
متن کاملThe antibacterial efficacy of trovafloxacin against an experimental infection with Listeria monocytogenes in hydrocortisone-treated mice.
The efficacy of trovafloxacin in treating Listeria monocytogenes infections in glucocorticosteroid-treated mice was compared with the efficacy of amoxycillin. Swiss mice were treated with daily injections of 2.5 mg hydrocortisone s.c. and then infected i.v. with 1 x 10(7) cfu of L. monocytogenes. Untreated, this level of infection resulted in 100% mortality between day 3 and day 5 after infecti...
متن کاملData on the effect of Cytopiloyne against Listeria monocytogenes infection in mice
Cytopiloyne (CP), a novel polyacetylene compound extracted from B. pilosa, shows a multi-bioactivity, including immunomodulatory and antidiabetes. Here, we investigated the anti-Listeria effect of cytopiloyne in mice by assessing mortality, clearance of L. monocytogenes, and pathology examination. The data presented herein are supplemental to our research article entitled "Cytopiloyne, a polyac...
متن کاملA protective role of gamma/delta T cells in primary infection with Listeria monocytogenes in mice
We have previously reported that T cells bearing T cell receptors (TCRs) of gamma/delta type appear at a relatively early stage of primary infection with Listeria monocytogenes in mice. To characterize the early-appearing gamma/delta T cells during listeriosis, we analyzed the specificity and cytokine production of the gamma/delta T cells in the peritoneal cavity in mice inoculated intraperiton...
