Syngeneic refers to a graft transferred between genetically identical animals or people. [1] A syngeneic graft is known as an isograft. [2] Related terms include: [citation needed] autogeneic, referring to autotransplantation, also termed autograft, (from one part of the body to another in the same person)
This discovery furthered the development of a previously hypothesized theory, the immunosurveillance theory. The immunosurveillance theory suggests that the immune system routinely patrols the cells of the body, and, upon recognition of a cell, or group of cells, that has become cancerous, it will attempt to destroy them, thus preventing the growth of some tumors.
Tumor-associated immune cells in the tumor microenvironment (TME) of breast cancer models. Cancer immunology (immuno-oncology) is an interdisciplinary branch of biology and a sub-discipline of immunology that is concerned with understanding the role of the immune system in the progression and development of cancer; the most well known application is cancer immunotherapy, which utilises the ...
Cell therapy (also called cellular therapy, cell transplantation, or cytotherapy) is a therapy in which viable cells are injected, grafted or implanted into a patient in order to effectuate a medicinal effect, [1] for example, by transplanting T-cells capable of fighting cancer cells via cell-mediated immunity in the course of immunotherapy, or ...
Post-HSCT oral cancer may have more aggressive behavior with poorer prognosis, when compared to oral cancer in non-HSCT patients. [ 63 ] A meta-analysis showed that the risk of secondary cancers such as bone cancer , head and neck cancers , and melanoma , with standardized incidence ratios of 10.04 (3.48–16.61), 6.35 (4.76–7.93), and 3.52 ...
According to a 2015 review article, Lewis lung carcinoma is the only reproducable syngeneic lung cancer model, meaning that it is the only reproducible lung cancer model that utilizes a transplant that is immunologically compatible. Syngeneic models have proven to be useful in predicting clinical benefit of therapy in preclinical experiments.
The next step in cancer immunoediting is the equilibrium phase, during which tumor cells that have escaped the elimination phase and have a non-immunogenic phenotype are selected for growth. Lymphocytes and IFN-gamma exert a selection pressure on tumor cells which are genetically unstable and rapidly mutating. Tumor cell variants which have ...
Tumor fragments retain cell-cell interactions as well as some tissue architecture of the original tumor, therefore mimicking the tumor microenvironment. Alternatively, a single-cell suspension enables scientists to collect an unbiased sampling of the whole tumor, eliminating spatially segregate subclones that are otherwise inadvertently ...
