Failure to reconstitute naive (CD45RA+) T-helper cells in the thymectomized host. CD45 isotype expression was examined on gated CD4+ cells identified by PerCP. The dot plots depict CD45RA+ (FITC, FL1) cells versus CD45RO+ (PE, FL2) cells. Columns A and B show the distribution of CD45 isoform expression at 6 and 9 months, respectively, after allogeneic BMT.
