← Human Body & HealthIf an individual with a genetic predisposition to peanut allergies experiences initial exposure, which consequence relating to immune sensitization follows?
A)Immediate anaphylactic shock develops rapidly
B)Suppression of T-helper cell response occurs
C)Complement-mediated cytotoxicity eliminates antigen
D)IgE antibodies bind to mast cells✓
💡 Explanation
Sensitization to an allergen, like peanuts, involves B cells producing IgE antibodies specific to peanut proteins; because these IgE antibodies then bind to mast cells and basophils. Therefore, upon subsequent exposure, crosslinking of these IgE antibodies triggers mast cell degranulation, rather than immediate anaphylaxis, suppression of T-helper cells, or complement-mediated cytotoxicity during initial sensitization.
