Abstract
Neutrophils are the most abundant leukocytes in the blood. In the recent decades, their crucial roles in host defense, immune regulation and tissue damage have been studied in a deeper dimension. In this protocol, we described a mouse model of immune complex-mediated vasculitis in the dorsal skin induced by Arthus reaction, and the subsequent analysis of edema, hemorrhage and tissue damage due to neutrophil activation by means of Evans blue area analysis, histology, and immunofluorescence. This protocol could facilitate the investigation of cellular therapy strategy against over-activated neutrophil-mediated tissue damage.
