Question

Cellular immunity takes care of

• A. Intracellular pathogens
• B. Pathogens in blood
• C. Both
• D. Pathogens in the tissue fluid

Answer 1

The correct option is A

Intracellular pathogens

Antibodies are secreted by B cells into the blood where they combat free pathogens. But antibodies cannot gain access to pathogens hidden inside cells. These pathogens are recognised and killed by other cells in the immune system, the T cells. These form a part of the cellular immunity.
