Question

multiple choice question
which cells are highly branched apcs found in the epidermis, mucous membranes, and lymphatic tissues?

t cells
dendritic cells
b cells
natural killer cells

Explanation:

To solve this, we analyze each option:

• T cells: Primarily involved in cell - mediated immunity, not highly branched APCs in the specified locations.
• Dendritic cells: Are antigen - presenting cells (APCs) with a highly branched structure. They are found in the epidermis (as Langerhans cells), mucous membranes, and lymphatic tissues.
• B cells: Involved in humoral immunity, mainly produce antibodies and are not the highly branched APCs in these locations.
• Natural killer cells: Part of the innate immune system, involved in killing infected cells, not APCs.

Answer:

B. Dendritic cells
