​T cells bind to antigens that have been engulfed, digested, and presented on the surface of a(n) ____.
A) ​macrophage
B) ​basophil
C) ​eosinophil
D) ​monocytes

Quizplus · Accepted Answer

T cells can only recognize antigens that have been presented on the surface of a cell by a major histocompatibility complex (MHC) molecule. Macrophages are antigen-presenting cells that engulf and digest foreign materials, and then present the resulting antigens on their surface via MHC molecules for T cells to recognize. Basophils and eosinophils are types of white blood cells that are not antigen-presenting cells, and monocytes are immature macrophages that have not yet differentiated into full-fledged antigen-presenting cells.
