CD4 and neoplasm: Multiple staining for CD4, CD8, CD204, and FoxP3 was also performed and the long SD (+) samples were all shown to exhibit significantly lower numbers of CD4+ (1.03E-08 vs. 9.51E-07, p = 0.0092) and CD8+ (1.69E-06 vs. 1.12E-05, p = 0.030) T cell infiltration, as well as a reduced number of CD204+ (5.91E-06 vs. 2.98E-05, p = 0.015) and FOXP3+ (1.04E-08 vs. 4.31E-07, p = 0.0095) cells in the tumor area.
