TREM-2 expression on CD14+ cells from BALF was increased in pulmonary sarcoidosis and HP patients compared with CG subjects in both presented variables: percentage of TREM-2+ CD14+ cells (Figure 1(c))—sarcoidosis: median: 34.79, IQR: 38.93; HP: median: 36.00, IQR: 26.04; CG: median: 12.98, IQR: 16.06 (sarcoidosis versus CG: P < 0.05; HP versus CG: P < 0.05) and MFI (Figure 1(d))—sarcoidosis: median: 4.68, IQR: 3.89; HP: median: 6.9, IQR: 4.76; CG: median: 3.62, IQR: 2.22 (sarcoidosis versus CG: P < 0.05; HP versus CG: P < 0.05). Here, CD14 is linked to pulmonary sarcoidosis.
