5. A patient comes into your doctor’s office (you specialize inimmunology and allergy) with a problem. Every time they get agastro-intestinal infection, they have a very severe inflamed gut.This doesn’t happen when they get either respiratory or skininfections. When you biopsy the iliac and mesenteric lymph nodes,you don’t find any B or T cells that are responsive to theinfection, which is a bit surprising. Based on the role of LN andGALT, explain why the above situation is unusual. Suggest anexplanation for what is occurring in this patient, and propose amethod for potentially helping them.
