Phenotypes of (A) primary peripheral blood macrophages from healthy subjects and lung cancer patients and (B) THP1-derived classically activated macrophage (M) and tumor-educated macrophage (TEM) models were determined before and after 3 days of heat-killed tuberculosis (HKTB) stimulation. Data with ≤ 50 cells within the gate were omitted. ns, not significant.
