Syk is required for neutrophil responses on immobilized His-C7‒anti-C7 immune complexes. (a) Respiratory burst, (b) cell spreading, (c) CXCL2, and (d) LTB4 release of WT and Syk‒/‒neutrophils. Curves in panel a show mean and standard error of the mean of 3 independent experiments; control data points were subtracted. Panel b is representative of 3 independent experiments. Graphs in c and d show mean and standard error of the mean from 3 independent experiments. See the text for actual P-values. Scale bar = 40 μm. C7, collagen type VII; His-C7, His-tagged fragment of the immunodominant NC1 domain of murine C7; LTB4, leukotriene B4; min, minute; WT, wild-type.
