Answer:
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines.
Step-by-step explanation:
T lymphocytes, ADCC, macrophages, natural killer (NK) cells, lymphokines, and monokines are the cells that are active during an immune response to a viral infection. These cells attack on the virus that is responsible for the infection. If the immune system is strong and these cells kills all viruses then no viral infection occurs while on the other hand, if these cells can't control the virus, the virus will cause infection in the body so these cells plays a vital role in prevention of infection.
