Figure Lengend Snippet: Profiles of myeloid subsets in NSCLC versus healthy subjects. (A) A representative gating strategy of CD13 + , CD14 + , CD15 + , and CD33 + cells in the leucocytes. (B) Statistical analysis of percentages of CD11b + HLA-DR - , CD13 + , CD14 + , CD15 + , and CD33 + cells in the leucocytes. (C) A representative gating strategy of CD13 + , CD14 + , CD15 + , and CD33 + cells in CD11b + HLA-DR - cells. (D) Statistical analysis of percentages of CD13 + , CD14 + , CD15 + , and CD33 + cells in CD11b + HLA-DR - cells. (E) Human leucocytes from healthy individuals were incubated with 10 µM Lalistat2 (L) or DMSO (S) for 24 hours. The percentages of CD11b + HLA-DR - , CD11b + CD13 + HLA-DR - , CD11b + CD14 + HLA-DR - , and CD11b + CD15 + HLA-DR - cells were analyzed by flow cytometry. C is the control without treatment. Data are expressed as mean±SD; experiments are independently repeated, n=19–20 for (B) and (D), n=6–7 for (E). *p<0.05, **p<0.01. NSCLC, non-small cell lung cancer.
Article Snippet: To inhibit LAL activity, human blood cells from healthy participants had the red cells removed with lysis buffer (BioLegend, San Diego, California, USA), washed with phosphate-buffered saline (PBS) by centrifugation at 240× g for 5 min at room temperature, and then incubated with 10 μM LAL inhibitor Lalistat2 (Cayman, Ann Arbor, Michigan, USA) for 24 hours.
