Moreover, increased numbers of CD14dimCD16+ non-classical monocytes (Fig. 4b, left panel, P = 0.04) and CD14+CCR7−CD163−CD206+ macrophages (Fig. 4d, left panel, P = 0.03) correlated with increased pulmonary pressures in SIV/Untreated Group 1 controls at 6 months post-infection. This evidence concerns the gene CD14 and infection.
