Testing Cancer Immunotherapeutics in a Humanized Mouse Model Bearing Human Tumors
Published on: December 16, 2022
Summary
Organ transplant recipients on immunosuppressive drugs show a high incidence of various cancers. This highlights the need to further investigate the role of immunosurveillance in preventing cancer in humans, which may differ from animal models.
Area of Science:
- Oncology
- Immunology
- Transplantation Medicine
Background:
- Organ transplant patients on long-term immunosuppressive therapy exhibit a notably high occurrence of diverse cancers, including carcinomas and lymphomas.
- This observation suggests a potential link between immune suppression and cancer development in this population.
Purpose of the Study:
- To review the exceptionally high incidence of various cancers in organ-transplant patients undergoing prolonged immunosuppressive drug treatment.
- To underscore the importance of investigating the role of immunosurveillance as a fundamental defense against cancer in humans.
Main Methods:
- Literature review of cancer incidence in organ-transplant patients.
- Analysis of the implications for the concept of immunosurveillance in human cancer prevention.
Main Results:
- Organ-transplant recipients on immunosuppressive drugs experience a disproportionately high rate of various cancers.
- The findings support the hypothesis that immunosurveillance plays a critical role in human cancer defense.
Conclusions:
- The elevated cancer rates in immunosuppressed transplant patients necessitate further research into the mechanisms of immunosurveillance.
- The function of immunosurveillance in humans may present unique aspects compared to experimental animal models.

02:53Adaptive Mechanisms in Cancer Cells
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

02:43Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

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...
