Question

Quizplus · Accepted Answer

Macrophages are antigen-presenting cells that engulf and process antigens, displaying them on their surface in combination with major histocompatibility complexes (MHCs). This allows lymphocytes to recognize and respond to the antigen. Helper T-cells can also present antigens, but they require processing by antigen-presenting cells such as macrophages first. B-lymphocytes, mast cells, and plasma cells do not typically present antigens to other immune cells.
