A six-month-old infant presents to your office with a history of multiple viral and bacterial infections. In your diagnosis, you discover that this infant's antigen-presenting cells are unable to produce MHC Class II proteins, and therefore the baby has a completely non-functional adaptive immune response. Which of the following choices may still be functional in this baby's immune system? A. Natural Killer Cells B. Cytotoxic T Cells C. Antibody production D. Helper T Cells E. Somatic hypermutation of B cells

Are comprised solely of phagocytic cells of the innate immune system c. Have both MHC I and MHC II protein complexes on their cell surface d.
