CD4 and pancreatic neoplasm: We also found that EPZ raised the population of CD4+ and CD8+ T cells to 68.7% (6,870 ± 77.21) and 48.5% (4,850 ± 82.61) compared to those in the Panc02 pancreatic cancer model as 66.9% (6,690 ± 78.52, P < 0.05) and 32.9% (3,290 ± 27.72, P < 0.05), but slightly lowered the differentiation of Tregs to 5.1% (510 ± 12.81) versus those in the Panc02 pancreatic cancer model as 5.3% (530 ± 17.01).
