FIG. 1.
Early LCMV production is reduced in the spleens of RAG2−/− mice. (A) Kinetics of LCMV-WE titers in the spleens of C57BL/6 mice and RAG2−/− mice following i.v. infection with 500 PFU of LCMV-WE. d, days. (B) Splenic LCMV titers on day 4 after LCMV-WE infection (500 PFU, i.v.) in C57BL/6, RAG2−/−, and RAG2−/− γc−/− mice (mean values for three to five mice per time point ± standard errors of the means; asterisks indicate levels below the detection limit).
