Summary
Cancer immunotherapy shows promise by targeting telomerase, a common cancer hallmark. Vaccines using human telomerase reverse transcriptase (hTERT) peptides activate T cells to fight tumors, offering a potential new cancer treatment.
Area of Science:
- Immunology
- Oncology
- Biotechnology
Background:
- Telomerase is a key characteristic of many cancers.
- Human telomerase reverse transcriptase (hTERT) is a validated tumor antigen.
- Anti-telomerase immunotherapies are emerging as a promising cancer treatment strategy.
Purpose of the Study:
- To review the current and potential applications of hTERT peptide antigens in cancer vaccines.
- To explore the challenges in developing telomerase-based cancer vaccines.
Main Methods:
- Review of studies on anti-telomerase cancer immunotherapy.
- Analysis of hTERT peptide vaccines and hTERT-specific T cell therapies.
- Examination of CD8+ cytotoxic T lymphocytes and CD4+ helper T lymphocytes responses to hTERT peptides.
Main Results:
- Vaccination with hTERT peptides or adoptive T cell transfer can lead to tumor regression.
- hTERT-specific T cells can lyse various hTERT-expressing tumor cells.
- Both CD8+ and CD4+ T cells are activated by hTERT-derived peptides.
Conclusions:
- hTERT peptide antigens are viable candidates for cancer vaccines.
- Telomerase-based immunotherapies hold potential for treating human cancers.
- Further research is needed to overcome experimental challenges in developing these vaccines.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
01:30Cancer Vaccines
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

02:15Replicative Cell Senescence
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...
02:57Targeted Cancer Therapies
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

02:17The Tumor Microenvironment
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
