The expression of PLZF (A), CD27 (B), CD44 (C), CD69 (D), PD1 (E) in γδ T cells in the tumor-bearing lungs and spleens were analyzed and compared between SPF and GF mice.
Results are expressed as the mean ± SEM. *p<0.05, ** p<0.01, *** p<0.001, **** p<0.0001 by Student’s t test. n= 2–5 mice/group; data represent 2–3 independent experiments. See also Figure S5.
