Question

Intestinal Epithelial Cells (IECs) carry out many immunological functions. One of these is to express Toll-like receptors. Which defensive cells are characterized by having Toll-like receptors that permit these defensive cells to identify and engulf several classes of foreign invaders? Intestinal Epithelial Cells (IECs) carry out many immunological functions. One of these is to express Toll-like receptors. Which defensive cells are characterized by having Toll-like receptors that permit these defensive cells to identify and engulf several classes of foreign invaders?

a. T cells

b. B cells

c. Plasma cells

d. Macrophages

Explanation / Answer

Defensive cells characterized by having Toll-like receptors that permit these defensive cells to identify and engulf several classes of foreign invaders are d. Macrophages

TLRs (Toll-like receptors) are a set of transmembrane receptors which are primarily found on macrophages, mast cells and dendritic cells.These three sentinal cells of the innate immune response recognize different types of PAMPs(Pathogen-Associated Molecular Patterns) by Toll-like receptors.
