SIRPA and infection: In spleens, the infected MΦ population changed over the course of infection, with red pulp MΦs (CD68+ CD11blow F4-80high MHC IIlow CD115+ CD172a+), marginal zone MΦs (CD68+ CD11b+ F4-80− SIGNR1+), tingible body MΦs (CD68+ CD11b−), and metallophilic MΦs being infected in the early acute and acute phase of infection, whereas metallophilic MΦs constituted the majority of infected spleen MΦs in the late phase of infection.
