PTPRC and infection: The numbers of neutrophils (CD45+CD11b+Ly6G+), and of NKT cells (CD45+CD3+NK1.1+), were modestly but significantly increased in μMT mice 8 weeks after infection, while the numbers of T cells (CD45+CD3+NK1.1−) and NK cells (CD45+CD3−NK1.1+) showed no significant changes between WT mice and μMT mice (Fig 2A).
