By percentage of live cells, we found that skin-resident cells (CD45−) and neutrophils were the predominant TNFR1- and TNFR2-expressing cells in the day 3 infected skin, whereas macrophages and monocytes accounted for lesser amounts of the TNFR1- and TNFR2-expressing cells during the infection (Fig. 2, E and F). Here, TNFRSF1B is linked to infection.
