Figure 3. Reduced RAG/IL-7R expression in DWEYS-MAP immunized IL-6+/− mice.
IL-6 heterozygous (IL-6+/−) mice (3-month old) and age-matched wild type BALB/c mice were immunized with DWEYS-MAP and boosted a week later (see Material and Methods). Antigen specific B cells were sorted on day 17 following the initial immunization and RNA was extracted for qPCR to check RAG and IL-7R mRNA (A). Spleen sections were frozen on the same day of sorting and immunohistochemistry was performed to detect RAG protein levels (B).
