Fig. 4. Dabrafenib and trametinib changed the cellular components of the tumor microenvironment.
Dabrafenib and trametinib changed the cellular components of the tumor microenvironment. On day 5 after ACT, spleens and tumors were isolated and stained with fluorescent-labeled antibodies and then analyzed by FACS, with three mice in each group (mean ± SD). (A) MO-MDSC (CD11b+Ly6CHiLy6GLo) presented as percentage of CD11b+ cells. *P = 0.06, pmel D versus pmel V in spleen; P = 0.009, pmel V versus mock V in tumor (unpaired t test, n = 3). (B) PMN-MDSC (CD11b+Ly6CLowLy6GHi) presented as percentage of CD11b+ cells. *P = 0.002, mock D + T versus mock V in tumor (unpaired t test, n = 3). (C) Analysis of macrophages (F4/80+CD11b+). *P = 0.04, pmel D versus pmel V; P = 0.002, pmel D + T versus pmel V, both in tumors (unpaired t test, n = 3). (D) Analysis of Tregs (CD4+CD25+FOXp3+). *P = 0.002, pmel D versus pmel V in tumors (unpaired t test, n = 3). (E) Gating strategy and representative FACS plots in tumors.
