Effect of hrAnx-A1 on differentiation of naive cells in effector cells in Th1 or Th2 conditions. Naive lymph node T cells were differentiated in vitro in Th1 (▪) or Th2 (□) condition in the presence or absence of the indicated concentrations of hrAnx-A1 and then restimulated with plate-bound anti-CD3 (5.0 μg/mL) for 8 hours to measure Th1 (top graphs) or Th2 (bottom graphs) cytokine production. Values are the mean ± SE of 4 to 5 mice. **P < .01.
