T cellsCytotoxic T cells fight pathogens and cancer by forming stereotyped cytotoxic immune synapses with infected or transformed target cells. We found that architectural changes in apoptotic target cells trigger the dissolution of immune synapses, providing a mechanistic basis for efficient synaptic turn...
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...
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?
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
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 ...
Do antibodies activate helper T-cells? How do cytotoxic T cells destroy cells bearing foreign antigens? How does the tetanus vaccine work? Do helper T-cells attach to pathogens? How do cytotoxic T cells destroy antigen bearing cells? Do helper T-cells bind to infections? How is the flu vac...

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 ...
see, the majority of the phagocytic cells that patrol our body hunting for pathogens stem from a common lineage, the CMP cells. However, another key player in the innate immune response, the cytotoxic natural killer (NK) cells, are derived from common lymphocyte progenitor (CLP) cells instead...
