Fig. 1 |. Recruitment versus training of the alveolar macrophage compartment.
a, One month after influenza infection, fetal monocyte-derived AMs (FeMoAMs, blue) as well as bone marrow monocyte-derived AMs (BMoAMs, red) developing during infection are present and might appear similar based on expression of general macrophage markers, such as CD64, MerTK and CD11c. b, Apparent training of the AM compartment. Using CD11c-positive selection for functional analysis, the AM compartment might appear to be trained due to elevated immunoreactivity contributed by BMoAMs. c, Detection of immunoreactive BMoAMs in functional assays. Using Siglec-F expression, congenic markers in bone marrow chimeric mice or lineage tracing approaches, FeMoAMs and BMoAMs can be functionally distinguished. Created with https://biorender.com.
