T CELLS
Storyboard Text
- Hey Charley, I want to ask you a questions.
- Yes Ana...
- Do you know the 3 main types of T cell?
- Yes, it is cytotoxic, helper, and regulatory
- That's right Charley, then what is the different role they play on the immune response.
- Cytotoxic T cells are activated by cytokines. They can attach to cancer cells and kill them.
- Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
- regulatory T cells have a role in regulating or suppressing other cells in the immune system. Tregs control the immune response to self and foreign particles (antigens) and help prevent autoimmune disease. Tregs produced by a normal thymus are termed 'natural'.
- Okay, now i know Charley.
- bye.
- Yah, I will go back to my house Ana. Thankyou for your time. Bye
