Colony stimulating factor 1 (Csf1, Cytokine cluster)was induced to a greater extent in cPLA2α-/- RPM (10-fold)than cPLA2α+/+ RPM (3-fold) (Table S2A).It promotes macrophage-lineage development but also recruits myeloid cellsduring inflammation and infection, and promotes their survival [55]. Here, CSF1 is linked to infection.
