ITGAM and infection: A previous study analysed subpopulations of monocytes present in the inflammatory infiltrate after infection with PbANKA revealed that both CCR2+-CD11b+ interstitial macrophages and Ly6Clow-CD11b+ monocytes increased 14 and 18 times, respectively, and that these populations originate from Ly6Chigh bone-marrow monocytes [55].
