Figure 6
Frequency of CD4+ IL-5+ cells after Der p-stimulation. PBMC were Der p-stimulated for 72 h and stained for CD4 and intracellular IL-5 as described in materials and methods. (a) Left panel, nonstimulated cells, central panel, Der p-stimulated cells and right panel, and Con A-stimulated cells; representative dot plots from three PAC patients. (b) Comparison of the frequency of CD4+IL-5+ cells among different stimuli. Data are expressed as mean ± SD.
