Which of the Following Cell Types Trigger an Immune Response

Question

Which of the following cell types trigger an immune response in the stratum spinosum?
A) Langerhans (dendritic) cells
B) keratinocytes
C) melaocytes
D) mast cells
E) Merkel cells

Accepted Answer

Langerhans (dendritic) cells are antigen-presenting cells found in the stratum spinosum layer of the epidermis. They are responsible for triggering an immune response by presenting foreign substances to T cells. Keratinocytes, melanocytes, mast cells, and Merkel cells are not known to trigger immune responses in this layer.
