  • a DR cells subjected to the indicated stimulation conditions were costained with peridinin chlorophyll protein-conjugated anti-CD4 and PE-conjugated anti-CXCR4 MAbs. Data were accumulated and analyzed as described in Materials and Methods. Data are representative of three experiments.

  • b US, unstimulated; anti-CD3, TCR stimulation alone (with anti-CD3); anti-CD3 + anti-CD28, costimulation.
