Expression of CD95, CD44, CTLA^-4, CD27, CCR7, CD62L, and CD38 by human CD4⁺ CD45RO^-/RA⁺ and CD45RO⁺/RA^- T cells in cord blood, adult blood and lymph node. Profiles are gated for live cells expressing CD4 and either CD45RA or CD45RO. Results are representative of 2 to 8 independent experiments for each sample.
