Q. The major antibody formed in anamnestic response is
Solution:
When our body encounters a pathogen for the first time it produces a weak or low intensity response, called primary response. In subsequent encounters with the same pathogen, the response becomes highly intensified. This response is called anamnestic or secondary response. It is because of the memory cells formed after the first encounter.
Two types of lymphocytes, B-cells and T-cells are involved in such response (immunity). IgG is the major antibody formed in the case of anamnestic response as it stimulates phagocytic cells, activates the complement system, binds neutrophils, opsonizes and can neutralise toxins. It also provides passive immunity to the baby by forming major line of defence during the first few weeks.
