Fig. 6. CD4+ and CD8+ T cell infiltration at week 20.

Fig. 6

Immunohistochemical staining for CD4 and CD8 was used to enumerate T cell infiltration into dorsal skin from the control and short-term/acute stress groups at week 20. Representative photomicrographs are shown for: (a) Control CD4+, (b) Acute Stress CD4+, (c) Control CD8+, and (d) Acute Stress CD8+ cells. Scale bar denotes 100 μm. Counts of CD4+ and CD8+ cells in the two treatment groups are shown in (e). Data are expressed as mean + 1 SEM. *P<0.05 for between-group means comparison within a T cell subset by unpaired Student’s t-test.
