Figure 4From: Dose response kinetics of CD8 lymphocytes from young animals transfused into old animals and challenged with influenzaNumbers of T cell subsets in the lymph nodes of individual mice within each of the experimental groups. Open circles (donor origin) are CD45.1+ and filled circles (host origin) represent CD45.1- cells. Solid bars indicate average numbers of cells of host origin and dashed bars indicate average numbers of cells of donor origin.Back to article page
