First, cytotoxic T-lymphocyte antigen 4 (CTLA4)–CD80/CD86 interactions induce the release of indoleamine 2,3-dioxygenase (IDO), a potent regulatory molecule, which induces the catabolism of tryptophan into pro-apoptotic metabolites. Second, lymphocyte-activation gene 3 (LAG3) binding to MHC class...
This beautiful and fascinating 2-minute video shows how killer T-cells, relentlessly hunt down and destroy cancer cells in your body.
T cell lineages are defined by specialized functions and differential expression of surface antigens, cytokines and transcription factors. Conventional CD4+ and CD8+ T cells are the best studied of the T cell subsets, but ‘unconventional’ T cells have
How do natural killer cells differ from cytotoxic T cells? How do undifferentiated cells become differentiated through epigenesis? The ability for cells to produce more cells is because of what process? How do animal cells complete the cell cycle?
It is now beyond doubt that different human tumor types can be recognized by the immune system and that cytotoxic T cells are a key player in this process. For long, efforts to understand and influence such tumor-specific T-cell reactivity have focused on the tumor-associated "self-antigens...
How do cytotoxic T cells respond to infected cells? What defense targets specific pathogens? What do neutrophils do? Where are neutrophils found? How does the humoral immune response work? How does the integumentary system help the immune system?
Cytotoxic T cells - Cytotoxic T cells release chemicals that break open and kill invading organisms. Memory T cells - Memory T cells remain afterwards to help the immune system respond more quickly if the same organism is encountered again. Suppressor T cells - Suppressor T cells suppress the ...

After T-cells have responded to the selection and training within the thymus, three basic types result: cytotoxic, helper and regulatory T-cells. Cytotoxic T-cells, or killer T-cells, have a lock-and-key arrangement with a specific antigen bound to a normal component of cells known as a ...
