A, Subjects with CIU have a bimodal distribution of basophil HR to an optimal dose of anti-IgE (0.1 μg/mL) compared with normal subjects. B, CIU NR had significant reductions in basophil anti-IgE dependent release compared with normal, CIU R, and cold urticaria subjects (∗P < ). FMLP-induced release differed significantly only between CIU NR and CIU R (∗∗P < .001). HrHRF response was tested in a smaller subset of donors (as indicated) and was not significantly different between subjects with CIU and normal subjects. C, Basophil HR was examined across a range of anti-IgE doses in normal donors and donors with CIU (∗P < CIU NR vs normal subjects and CIU R). D, HR is presented as a percent of the maximal response achieved (see Methods).

Expression of Syk, SHIP-1, and SHIP-2 protein in basophils from donors with CIU, donors with cold urticaria, and normal (Nor) donors. A, Representative immunoblots shows a Nor, 2 CIU R, and 2 CIU NR donors. The scanned values were normalized to the T-cell standard lysate (Std) and corrected for cell equivalents (bottom). The upper panel demonstrates the expected 72-kd band of Syk, and the middle panel the expected band of 145 kd for SHIP-1, whereas the lower panel reveals the expected 155-kd SHIP-2 protein band. B, Mean values of Syk protein expression were not different among donor types. C, Mean normalized values for expression of SHIP-1 and SHIP-2 protein. SHIP-1 expression is reduced in cold urticaria and CIU R (∗P < .05 vs normal; #P < .05 vs CIU NR). SHIP-2 expression is increased in CIU NR compared with normal subjects (∗P < 0.05) and CIU R (#P < .03). Error bars represent SEMs.

Expression of phosphoAkt in basophils from CIU NR, CIU R, and a normal donor. A, Basophil lysates were examined at the indicated time points after stimulation with anti-IgE ( μg/mL) for the expression of phosphoAkt and Erk. B, Phosphorylated Akt (pAKT) expression normalized to ERK protein (anti-IgE 0.1 μg/mL, dashed lines; 0.3 μg/mL, solid lines). Immunoblot representative of 2 to 3 similar experiments.
