Question

Of the following cells, which could be considered a "professional" antigen-presenting cell?
A) neutrophil
B) T lymphocyte
C) natural killer cell
D) dendritic cell
E) fibroblast

Dendritic cells are considered professional antigen-presenting cells because they have the ability to activate naive T cells and initiate an adaptive immune response. Neutrophils, T lymphocytes, natural killer cells, and fibroblasts do not have this specific function.
