Tolerance to IMQ is dependent on MMP10. (A) Schematic diagram of in vivo tolerization protocol. (B,D) Back skin from wildtype and Mmp10−/− mice treated with 1- or 2-hit model was homogenized and total RNA was isolated. Expression of target mRNAs was measured using qPCR and normalized to untreated (control) wildtype mice, n = 7–10 mice per group from two independent experiments. (C) Single cells isolated from back skin tissue were stained for CD45 and Ly6G. The frequency of Ly6G+ cells (a marker of neutrophils) on pre-gated CD45+ cells was assessed by flow cytometry.
