01:27Tumor Immunotherapy
1.8K
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.

This video demonstrates an in-situ fluorescence multispectral imaging technique to analyze different subpopulations of infiltrating T cells in tumor tissue. A renal cell carcinoma tissue cryosection is treated with antibodies to label CD8+ T cells that express specific inhibitory receptors and exhibit an immunotherapy-resistant phenotype. The labeled section is visualized using a multispectral microscope to identify the distinct CD8+ T cell...

The most commonly used method for generating large numbers of autologous dendritic cells (DCs) for use in tumor immunotherapy is described. The method uses IL-4 and GM-CSF to differentiate DCs from monocytes. The immature DCs are stimulated to mature and then loaded with antigens before they are injected back into the...
