Elevated numbers of CD44hiCD45RBlo CD4+ T cells in B6.TNF−/− mice. EAE was induced in B6.TNF−/− and C57BL/6 mice by MOGp35–55 immunization with or without PTx coadministration, and CD44 and CD45RB phenotypes of CD4+ T cell were analyzed and compared with age-matched nonimmunized mice 9–11 wk later by flow cytometry. Each plot depicts CD4, CD44, and CD45RB phenotypes in total spleen cells pooled from four to five mice. Numbers underneath the regions represent the percentage of CD44hi or CD45RBloCD4+ T cells, expressed as percentage of total CD4+ T cells. The percentage of total CD4+ T cells in the spleens of the different groups did not vary significantly.
