What is killer t cells

This transfer happens in the lymph nodes, which are located throughout your body. Lots of lymph nodes are in your legs, armpits, and neck. The last time you had a sore throat you probably felt enlarged places on one or both sides of your neck. This is where the T-cells and B-cells multiply and get ready to attack the virus. Other important parts of the lymph system where immune cells grow, multiply, and trap invaders are your bone marrow, thymus, spleen, and tonsils.
