Nonpolarized T cells express CCR7 which is required for lymph node homing. (A) In vitro migration to SLC of naive (○), nonpolarized (•), Th1 (▪), and Th2 (▴). One representative experiment out of four. (B) Lymph node/spleen ratio of transferred T cells preincubated with medium alone (striped bars) or 15 μg/ml SLC (black bars). NP, nonpolarized.
