There is an urgent need for innovative therapies against ovarian cancer, one of the leading causes of death from gynecological cancers in the United States. Immunotherapy employing Toll-like receptor (TLR) ligands, such as CpG oligodeoxynucleotides (CpG-ODN), may serve as a potentially promising approach in the control of ovarian tumors. The CpG-ODN(More)
DNA vaccines have emerged as a potential alternative to current strategies to control cancer for their safety, stability and ease of preparation. We have previously demonstrated that a DNA vaccine encoding calreticulin (CRT) linked to human papillomavirus type 16 (HPV-16) E7 antigen (CRT/E7) can generate significant E7-specific immune responses and(More)
Cervical cancer continues to be the second largest cause of cancer deaths in women worldwide. Persistent infection with high-risk types of human papillomavirus (HPV) is a necessary cause of cervical cancer. Thus, prophylactic vaccination against HPV is an attractive strategy to prevent cervical cancer. Current strategies for the development of safe and(More)
More than 99% of cervical cancers have been associated with human papillomaviruses (HPVs), particularly HPV type 16. The clear association between HPV infection and cervical cancer indicates that HPV serves as an ideal target for development of preventive and therapeutic vaccines. Although the recently licensed preventive HPV vaccine, Gardasil, has been(More)
Human papillomavirus (HPV), particularly type 16, has been associated with more than 99% of cervical cancers. There are two HPV oncogenic proteins, E6 and E7, which play a major role in the induction and maintenance of cellular transformation. Thus, immunotherapy targeting these proteins may be employed for the control of HPV-associated cervical lesions.(More)
The clearly defined causation by papillomavirus (HPV) and precursor lesions of cervical cancer have made this cancer largely preventable through Pap screening programs, and now by vaccination with Gardasil. This represents an important public health success story and here the authors summarize the potential impact of preventive HPV vaccination and some of(More)
The high-risk types of human papillomavirus (HPV) have been found to be associated with most cervical cancers and play an essential role in the pathogenesis of the disease. Despite recent advances in preventive HPV vaccine development, such preventive vaccines are unlikely to reduce the prevalence of HPV infections within the next few years, due to their(More)
PURPOSE Because the combination of multiple modalities for cancer treatment is more likely to generate more potent therapeutic effects for the control of cancer, we have explored the combination of chemotherapy using cisplatin, which is routinely used in chemotherapy for advanced cervical cancer, with immunotherapy using DNA vaccines encoding calreticulin(More)
Cervical cancer is one of the most common cancers in women worldwide. Persistent infection with human papillomavirus (HPV) is considered to be the etiological factor for cervical cancer. Therefore, an effective vaccine against HPV infections may lead to the control of cervical cancer. An ideal HPV vaccine should aim to generate both humoral immune response(More)
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 papillomavirus 16 (HPV-16) combined with DNA encoding invariant (Ii) chain in which class II-associated Ii peptide (CLIP) region is replaced with(More)
