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.

• Why does severe lymphedema increase susceptibility to skin infections?
• Why does decreased serum phosphate result in impaired bone mineralization?
• Why does long-term hyperglycemia increase the risk of neurodegenerative diseases involving tau protein aggregates?
• Why does inhibition of a specific enzymatic pathway often lead to vitamin deficiency symptoms, such as those observed in scurvy or beriberi?
• Why does carbohydrate fermentation in the colon produce gas, rather than complete oxidation to CO2 and H2O as occurs during cellular respiration?
• Why does osmotic diuresis, as seen in poorly controlled diabetes, cause significant electrolyte imbalances in the renal system?
