Q) Most potent cells that present antigen and are distributed throughout the lymphoid and nonlymphoid tissues of the body are?
✅ Answer: A. Dendritic cells
🔍 Explanation:
Dendritic cells are specialized macrophages and are considered professional antigen presenting cells (APCs). They are the most potent APCs in the body, distributed widely in both lymphoid and non-lymphoid tissues.
🧠 NK cells are large granular lymphocytes involved in innate immunity. They have cytolytic functions but are not classified as APCs.
🧠 Macrophages and monocytes can present antigens but are less efficient compared to dendritic cells.
