Irradiation of mice with a dose of 600 rad of total body irradiation eliminates 95% of total lymphocytes from spleen and lymph nodes and also eliminates all antigen-specific memory B cells. Nonetheless, when Influenza A-infected mice are subjected to this irradiation at 60-days post-infection, and then reconstituted with bone marrow cells from a naive mouse (this replenishes all of the lymphocyte populations), the levels of circulating anti-Influenza A IgG antibodies show nearly no decline when mice are monitored for the following year. What is the explanation for this finding?
