CD4⁺ T cell population markers (Th1, Th2, Treg and others) in mouse pancreatic tumor tissues. (A-D) PDAC (KPC) tumor-bearing C57BL/6 mice were treated as described in Fig. 1E. The expressions of CD4⁺ T cell markers for (A) Th1, (B) Th2, (C) Treg, and (D) other T cell populations were measured by qRT-PCR. Statistical analyses: data are means ± SEM of three biological replicates; two-tailed unpaired T-test for A-D. *, P < 0.05.
