SLAMF1 and infection: In parallel with parasite burden, the proportion and number of bone marrow Lin-Sca-1+c-Kit+ (LSK) cells and CD150+CD16/CD32-LSKs, which correspond to an HSC-like phenotype in uninfected mice, also increased, reaching a plateau between day 21 and day 28, depending on the strength of the infection (Fig 1B and 1C, S1 Fig).
