FIGURE 4.
The numbers of lymphocytes in tumor-bearing lungs are decreased in the setting of 5-LO-KO in the TME. (A) Sequential flow cytometry gating strategy to identify lymphocytes in tumor-bearing lungs: NK cells (NK 1.1+/CD3−), CD3 cells (CD3+/SSCLow), CD4 cells (CD3+/CD4+), and CD8 cells (CD3+/CD8+). (B) Flow cytometry–based quantitation of CD3, CD4, and CD8 cells in tumor bearing lungs from WT and 5-LO-KO mice, harvested 2.5 wk after LLC-Luc cells injection. Each dot represents a single mouse. Data represent three separate flow analyses. (C) Quantitation of NK cells and dendritic cells (DC). DC were identified using myeloid marker panel (CD11cHi/MHC class IIHi/SigF−). (D) Number of CD3-positive cells was assessed by immunohistochemistry. Quantification was performed in sections from six WT and four 5-LO-KO mice.
