Innovative DNA vaccine for human papillomavirus (HPV)-associated head and neck cancer
Human papillomavirus (HPV), particularly type 16, has been associated with a subset of head and neck cancers. The viral-encoded oncogenic proteins E6 and E7 represent ideal targets for immunotherapy against HP...

Efficient delivery of DNA vaccines using human papillomavirus pseudovirions
We have examined non-replicative human papillomavirus (HPV) pseudovirions as an approach in the delivery of naked DNA vaccines without safety concerns associated with live viral vectors. In this study, we have...

Enhancing DNA vaccine potency by co-administration of xenogenic MHC class-I DNA
Intramuscular administration of DNA vaccines can lead to the generation of antigen-specific immune responses through cross-priming mechanisms. We propose a strategy that is capable of leading to local inflamma...

Multitarget therapy of malignant cancers by the head-to-tail tandem array multiple shRNAs expression system
Coexpression of multiple shRNAs can simultaneously inhibit multiple genes or target multiple sites on a single gene. These approaches can be used for dissecting complex signaling pathways and even be applied t...

Article
Cluster intradermal DNA vaccination rapidly induces E7-specific CD8+ T-cell immune responses leading to therapeutic antitumor effects
Intradermal administration of DNA vaccines via a gene gun represents a feasible strategy to deliver DNA directly into the professional antigen-presenting cells (APCs) in the skin. This helps to facilitate the ...

Article
Role of IL-2 secreted by PADRE-specific CD4+ T cells in enhancing E7-specific CD8+ T-cell immune responses
CD4+ T helper cells are known to play an integral role in the generation of CD8+ T-cell immune responses. We have previously shown that co-administration of DNA vaccines containing E6 or E7 protein of human papil...

Control of human mesothelin-expressing tumors by DNA vaccines
Mesothelin has been implicated as a potential ideal target antigen for the development of antigen-specific cancer immunotherapy for the control of mesothelin-expressing cancers such as ovarian cancer, mesothel...

Article
Control of mesothelin-expressing ovarian cancer using adoptive transfer of mesothelin peptide-specific CD8+ T cells
Cancer immunotherapy targeting mesothelin represents a potentially plausible approach for the control of ovarian cancer as most ovarian cancers express high levels of mesothelin. In the current study, we creat...

Vaccinia virus preferentially infects and controls human and murine ovarian tumors in mice
Vaccinia virus has been shown to efficiently infect tumor cells. Therefore, vaccinia virus represents a potentially safe and effective antitumor agent against ovarian cancer. Here, we assessed the ability of v...
