A patient undergoing chemotherapy experiences severe neutropenia. If granulocyte colony-stimulating factor (G-CSF) is administered, which consequence follows concerning their immune response?

💡 Explanation

G-CSF stimulates the bone marrow to produce more neutrophils; these neutrophils are phagocytes that engulf and destroy pathogens. Consequently, enhanced phagocytosis occurs. This is because G-CSF directly boosts the number of phagocytic cells, therefore, the immune system can better clear infections, rather than autoimmune reactions, reduced antibody responses, or diminished T cell activation.
