IL10 and infection: Similarly, we did not observe any differences in IL-10-Thy1.1 expression during the early phase of chronic LCMV infection on myeloid cells (Supplementary Fig. 3C), but found a trend toward decreased expression of IL-10-Thy1.1 in CD11b+Ly6G+ cells during the chronic stage of the infection (Supplementary Fig. 3D), however, this did not reach significance.
