Fig. 5. AAV-LAV-BPIFB4 tunes lower CD38 expression in aged blood and bone marrow monocytes shaping an anti-inflammatory microenvironment.

Fig. 5

Blood and bone marrow monocytes in n = 3 Old-GFP mice and n = 3 Old-AAV-LAV-BPIFB4 mice were interrogated by flow cytometry gating on CD45+F4/80-Ly6C+CD38+ cells. Panels show A circulating monocytes and B bone marrow resident monocytes frequency in n = 3 Old GFP mice and n = 3 Old-AAV-LAV-BPIFB4 mice. C Histogram shows the amounts of CD45+F4/80-Ly6C+CD38+ monocytes in bone marrow regarding the stratification in Ly6Chigh and Ly6Clow monocytes (*P < 0.05). Results are expressed as mean ± SD. Pairwise comparisons statistically significant are indicated (ANOVA; *P < 0.05, **P < 0.01). Statistical evaluation was carried out by ordinary one-way ANOVA corrected for Tukey’s multiple comparisons test (GraphPad® Prism). D IL-27 and E TNF-α secretion levels in bone marrow microenvironment of Old-GFP mice vs Old-AAV-LAV-BPIFB4 mice (*P < 0.05) expressed as mean ± SD. Statistical evaluation was carried out by ordinary one-way ANOVA corrected for Tukey’s multiple comparisons test (GraphPad® Prism).
