CCR3 and CCR5 expression in HD and control lymph nodes.

Immunohistochemical staining of lymph nodes involved by HD with mAb directed against CCR5 (A), CCR3 (B), and isotype-matched control antibody (C). No CCR5 expression is detectable in control lymph nodes with follicular hyperplasia (D). Graphs show percentage of CCR5- and CCR3-expressing cells in T-cell subsets sorted from control (■) and HD lymph nodes (▪). The graphs represent the mean percentage (SE) of stained cells of 5 distinct experiments.
