A patient who can produce antibodies against some bacterial pathogens, but not against viral infections, probably has a disorder in his

Question

Quizplus · Accepted Answer

Antibodies against viral infections are produced by T cells, so a disorder in T cells would prevent the patient from producing antibodies against viral infections. B cells produce antibodies against bacterial pathogens, so a disorder in B cells would not explain the patient's inability to produce antibodies against viral infections. Plasma cells are fully differentiated B cells that produce antibodies, so a disorder in plasma cells would also not explain the patient's inability to produce antibodies against viral infections. Natural killer cells are part of the innate immune system and do not produce antibodies, so a disorder in natural killer cells would not explain the patient's specific antibody deficiency. Macrophages are also part of the innate immune system and do not produce antibodies, so a disorder in macrophages would not explain the patient's specific antibody deficiency.
