ITGAX and infection: Compared to that at 3 months post-infection, increased expression of ARG-1 was observed in SSClowCD11b+F4/80+, CD11b+CD11c+ and CD11b+Gr-1+Ly-6C−Ly-6G+ cells from infected mice at 6 months (F(3, 12) = 3.963, P < 0.001; F(3, 12) = 26.29, P < 0.001; and F(3, 12) = 16.46, P < 0.001, respectively).
