Figure 4

Regulatory cells and apoptosis in achalasia. Immunohistochemistry for (a) CD25/Foxp3 T cells, (c) CD20/IL-10 B cells, and (e) FAS cells in control and achalasia sections. Arrows depict immunoreactive cells. Original magnification was ×320. Results are expressed as mean (yellow line), median (black line), and 5th/95th percentiles of (b) CD25/Foxp3⁺ T cells, (d) CD20/IL-10⁺ B cells, and (f) FAS⁺ cells.
