Which type of granulocyte in the immune system carries clusters of differentiation (CD) receptors on its surface?
A
Erythrocytes
B
Neutrophils
C
Fibroblasts
D
Platelets
Verified step by step guidance1
Understand that granulocytes are a category of white blood cells characterized by the presence of granules in their cytoplasm. The main types include neutrophils, eosinophils, and basophils.
Recall that clusters of differentiation (CD) receptors are molecules found on the surface of immune cells that help in cell signaling and identification. Different immune cells express different CD markers.
Identify which granulocyte type is known for expressing a variety of CD receptors on its surface. Neutrophils, as key players in the innate immune response, carry several CD markers that facilitate their role in recognizing and responding to pathogens.
Note that erythrocytes (red blood cells), fibroblasts (connective tissue cells), and platelets (cell fragments involved in clotting) are not granulocytes and do not carry CD receptors in the context of immune cell identification.
Conclude that among the options, neutrophils are the granulocytes that carry clusters of differentiation (CD) receptors on their surface, enabling them to participate effectively in immune defense.
