Immunohistochemical staining for CD3⁺, CD4⁺, CD8⁺, MHC class II was performed on the same mice described in Fig. 3. Naive animals were analyzed at the same time. The sections were scored using a 0–4 scale (20) to grade portal inflammation. The mean values are given within each experimental group (n = 3) and the standard deviations are given in parentheses.
